Applications to choose the best DNS for the connection.

There are several DNS servers to use. In fact, some are free and some are paid. For example: 8.8.8/8.8.4.4), Cloudflare (1.1.1/1.0.0.1) or OpenDNS Home (208.67.222.222/208.67.220.220). However, today we will show you some tools to choose the best DNS server available.

DNS Jumper

It is one of the most popular apps for selecting the best DNS. It also allows you to change it automatically from the menu itself. Its way of working is very simple. The tool shows a list with the fastest DNS available in the database.

At the bottom there are some filters. For example turbo mode or mixed mode. This way it is possible to limit the maximum response time. After setting the parameters you just have to click on Start DNS Test. This will start the search for the fastest DNS server for the connection. The result is very complete since it shows the name and the DNS values. Then you just need to configure the connection. You can download it from here.

DNS Benchmark

This tool offers very complete information about DNS servers. In effect, this makes your work take a little longer. However, it is worth the wait. After downloading and running it, you must click on Nameservers. Then please wait a few moments while the server list is loading. Then press the Run Benchmark button.

After a few moments, the tool shows the fastest DNS servers for the connection.

NameBench

This tool has not been updated for a long time. However, it is still widely used when determining the best DNS server. Indeed, it is a very complete application. Since it performs a standard test. But it also uses the browsing history to perform the speed test. In this way it is possible to determine the best configuration for the current location and connection. Please note that the test will take many minutes. A report will be displayed in the web browser after completion. You can download it from here.

DNS Perf

This tool is executed differently. That is, it is not a tool but a web page. Therefore, it is not necessary to download anything, but go directly to the website. In other words, it is a benchmark website that allows you to know which are the fastest DNS servers. Taking into account the location and type of connection.

When visiting the page, a list of DNS servers is displayed. In addition, they are ordered by response time so that you can choose the one with the highest speed. Clicking on any result will show IP addresses, response time and quality of service. An interesting aspect is that it allows you to filter the search by continents.

In this way we have seen how to search for the best DNS for Windows 10. In addition to tools, there is also the option to search directly in the browser. All right, this is all for now. See you next time!

Why change it

There are many reasons to change the DNS in Windows 10. But in reality, the improvement is felt at the level of security and speed. For example, to obtain more speed of navigation, to accede to portals, services and blocked Web pages in our country. In addition, adults can implement a parental control system. Additionally, there are other advantages such as:

• Reliability as they tend to offer greater stability and more real uptime
• Speed that is placed, in some cases, ahead of the operators’ servers
• Security as some offer phishing protection or DNSSEC support.
• Parental control by having options such as filtering access to pages not recommended for minors.
• Skip restrictions to continue accessing domains blocked by the operator.

How to change the DNS from the Windows 10 network configuration

This procedure is relatively simple to do. However, we recommend special attention for novice users. The first thing you need to do is to enter the Windows settings. With this in mind, press the Windows +I combination, once there click on Network & Internet.

The Internet and Networking menu will be displayed immediately. On the right-hand menu, click on Change Adapter Options.

Next you will see the Network Connections section in the Control Panel. Now it is time to select the current active connection. In this example the connection is managed by the Wi-Fi network. Therefore, double click to enter the network properties.

Within the network properties a number of elements are displayed. Please scroll down to get Internet Protocol version 4 (TCP/IPv4). Now click on Properties.

Then follow the next steps. In the first place click on Use the following DNS Server address. Then manually fill in the Preferred DNS Server and Alternate DNS Server options. Finally, check the box Validate settings upon exiting.

Now it is time that everything is in order. With this intention, from a CMD runs the following command:

ipconfig /all

However, we recommend testing the effectiveness of DNS in the connection. Inasmuch as, a DNS server may be a good option for one person or in one country, and not work as well in other conditions. Indeed, DNS Benchmark, NameBench and DNS Perf are used to locate the fastest DNS. Some also offer additional features such as security and parental control. Very well, this way we have seen how to change DNS in Windows 10. This allows to increase the speed of Windows internet browsing. See you soon.

How to install the DNS role in Windows Server 2019/2016.

Most commonly, this role has been installed along with the Active Directory role. Most commonly, this role has been installed along with the Active Directory role. So if you have reviewed our posts on Windows Server you should already know how to do it. However, I remind you of the steps. In the first place, from the Server Manager click on Add Roles and Features

Press Next to continue

Now select the type of installation. In this case, we will use the role or feature based installation.

Please select the server where the DNS server will be installed.

Below, you can see the DNS role already installed. If not, check the box and follow the instructions in the wizard.

Setting up a DNS server in Windows Server 2019/2016.

Once the installation is verified, it is time to configure the DNS role. To do this, once again we will use the Server Manager. Once there, please enter the Tools menu. Then, click on DNS:

Then the DNS manager will be displayed. Please right-click on the name of the server. Then select Configure a DNS Server.

The DNS Server Configuration Wizard will be displayed immediately. Press Next to continue.

Now it is time to select the optimal alternative for the zone to be used on the server. If you are using small networks, then I recommend creating a forward lookup zone.

Now please set the location of the primary server. This time, the server maintains the zone.

Then assign the name of the zone.

Now it’s time to set up how to receive updates. For security reasons, I recommend using the first option.

In this option, it is possible to configure the DNS server as a temporary reseller. This is very interesting, as it allows our DNS server to query other external DNS servers. This is in the case of those records that it is not able to resolve itself. With this in mind, please add the IP address of the external DNS server.

After this step, the assistant will have finished his work. After this step, the assistant will have finished his work.

Finally you will be able to see the area created correctly. Consequently, the DNS server administration is now available on Windows Server.

Conclusion

Well, in this simple way we have seen how to install and configure a DNS server in Windows Server 2019/2016. Therefore, the administrator has this important feature. All right, that’s it for now. Before saying goodbye I invite you to see our post about activating Wi-Fi in Windows Server. See you soon!

What is a DNS

Domain Name Servers are responsible for translating web addresses into IP addresses. That is to say, when you enter osradar.com, you enter that address, but the web browser needs another method to know which server to connect to. In other words, when you access osradar.com, the DNS servers translate that text to an IP address. If they don’t exist, then you would have to manually enter all the IP addresses of the websites. This process is done automatically. That is, the user does not intervene in the name resolution. However, the main reason for changing the DNS on your mobile device is privacy. In effect, when you connect through your router’s default DNS, then your identification and your IP is exposed. On the other hand, countries with authoritarian regimes like Venezuela, use DNS to block access to certain critical sites.

So, changing the DNS increases privacy, bypasses blocking and in some cases improves response time on the web.

Changing the DNS in Android.

Once we have seen the utility of modifying the DNS in Android, let’s see how to do it. This is a relatively simple procedure and no external programs are used. First of all, you have to choose a DNS to use. Check here Once we have seen the utility of modifying the DNS in Android, let’s see how to do it. This is a relatively simple procedure and no external programs are used. First of all, you have to choose a DNS to use. Check here a list of free DNS servers. In my case, I will be using Cloudfare’s DNS servers, but you can use anyone you’re comfortable with. Then, just enter the WiFi settings.

Once there, enter the configuration of the network you are connected to, to be able to edit it.

Then enter the IP configuration.

Then change the DHCP setting to Static.

Finally, in DNS 1 and DNS fields, add the values 1.1.1.1 and 1.0.0.1 Then save the changes and wait a few moments while the system reconfigures the connection.

Conclusion

Finally, we have seen how to change the DNS in Android. As mentioned, this action increases the user’s privacy. It is also a tool against government censorship. On the other hand, sometimes it improves the response time of the web pages. This is all for now. I invite you to see our post about Symfony on Windows 10. Goodbye!

The post What is DNS and how to change it in Android appeared first on Linux Windows and android Tutorials.

In this tutorial you will learn that how to install and configure your own DNS server on the RHEL 8 and CentOS 8 server.

My Server Details:

Operating System:  RedHat Enterprise Linux 8
Hostname:               primary.osradar.localdomain
IP Address:             192.168.130.152

STEP 1:
Install bind (DNS) packages on your server.

yum install bind bind-utils -y

STEP 2:
Configure DNS Server

Edit /etc/named.conf file using below command and make below changes.

vi /etc/named.conf

i: Comment below lines so BIND DNS Server will listen to all IP addresses.

#listen-on port 53 { 127.0.0.1; };
#listen-on-v6 port 53 { ::1; };

ii: Add your network in below line, It will allow clients to query the DNS for the name (URL) to IP translation. My network is 192.168.130.0/24

allow-query { localhost; 192.168.130.0/24; };

iii: Create Forward and Reverse Zones

zone "osradar.localdomain" IN {
type master;
file "forward.osradar";
allow-update { none; };
};
zone "130.168.192.in-addr.arpa" IN {
type master;
file "reverse.osradar";
allow-update { none; };
};
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
#listen-on port 53 { 127.0.0.1; };
#listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
secroots-file "/var/named/data/named.secroots";
recursing-file "/var/named/data/named.recursing";
allow-query { localhost; 192.168.130.0/24; };

/*
- If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
- If you are building a RECURSIVE (caching) DNS server, you need to enable
recursion.
- If your recursive DNS server has a public IP address, you MUST enable access
control to limit queries to your legitimate users. Failing to do so will
cause your server to become part of large scale DNS amplification
attacks. Implementing BCP38 within your network would greatly
reduce such attack surface
*/
recursion yes;

dnssec-enable yes;
dnssec-validation yes;

managed-keys-directory "/var/named/dynamic";
pid-file "/run/named/named.pid";
session-keyfile "/run/named/session.key";

/* https://fedoraproject.org/wiki/Changes/CryptoPolicy */
include "/etc/crypto-policies/back-ends/bind.config";
};

logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};

zone "." IN {
type hint;
file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

zone "osradar.localdomain" IN {
type master;
file "forward.osradar";
allow-update { none; };
};
zone "130.168.192.in-addr.arpa" IN {
type master;
file "reverse.osradar";
allow-update { none; };
};

STEP 3:
Create DNS Zone files

Create forward and reverse zone files which was added in the /etc/named.conf file.

i: Create Forward Zone

Create forward.osradar file in the /var/named directory.

vi /var/named/forward.osradar

Add the following lines:

$TTL 86400
@ IN SOA primary.osradar.localdomain. root.osradar.localdomain. (
2011071001 ;Serial
3600 ;Refresh
1800 ;Retry
604800 ;Expire
86400 ;Minimum TTL
)
@ IN NS primary.osradar.localdomain.
@ IN A 192.168.130.152

primary IN A 192.168.130.152

ii: Create Reverse Zone

Create reverse.osradar file in the /var/named directory.

vi /var/named/reverse.osradar

Add the following lines:

$TTL 86400
@ IN SOA primary.osradar.localdomain. root.osradar.localdomain. (
2011071001 ;Serial
3600 ;Refresh
1800 ;Retry
604800 ;Expire
86400 ;Minimum TTL
)
@ IN NS primary.osradar.localdomain.
@ IN PTR osradar.localdomain.
primary IN A 192.168.130.152

152 IN PTR primary.osradar.localdomain.

STEP 4:
Start the DNS service

systemctl start named
systemctl enable named

STEP 5:
Configure Firewall

We must allow the DNS service or its port 53 in firewall.

firewall-cmd --permanent --add-port=53/tcp
firewall-cmd --permanent --add-port=53/udp
firewall-cmd --reload

STEP 6:
Adding DNS Server in Network

Add the DNS Server IP in network interface file.

vi /etc/sysconfig/network-scripts/ifcfg-ens32

Note: ifcfg-xxxx will be your network interface file

I will add below entry as it is my DNS server IP address
DNS=”192.168.130.152″

Add DNS server IP in /etc/resolv.conf

vi /etc/resolv.conf

nameserver 192.168.130.152

Now restart Network

systemctl restart NetworkManager.service

OR

systemctl restart network

STEP 7:
Test DNS Server

dig primary.osradar.localdomain

Output

Address: 192.168.130.152

Client Machine Configuration

Add the DNS server details in /etc/resolv.conf file of all desired client machines.

Run below command

vi /etc/resolv.conf

Then add below entry in that file where 192.168.130.152 will be replaced with your DNS server IP address.

nameserver 192.168.130.152

Now restart Your Network using one of following commands

systemctl restart NetworkManager.service

OR

systemctl restart network

Test DNS Server from Client machine

dig primary.osradar.localdomain

nslookup osradar.localdomain

That’s it. You have successfully installed BIND DNS on RHEL 8 / CENTOS 8 as master (Primary) server and now it is ready to use.
