If you want to create a website or host a server on your network, you need to know how to manage DNS records. DNS stands for Domain Name System, and it is the backbone of the internet. DNS translates domain names, like google.com, into IP addresses, like 172.217.164.110. In this article, we will guide you on how to add a record to your DNS server.
Step 1: Access your DNS server
The first step is to access your DNS server. You can use any DNS server, but for this tutorial, we will use the BIND DNS server, which is a popular DNS server that runs on Linux. You can access your DNS server through SSH, or if you have a graphical user interface (GUI), you can use a remote desktop tool like VNC.
Step 2: Open the configuration file
Once you have accessed your DNS server, the next step is to open the configuration file. The configuration file is where you will add your DNS record. The configuration file for BIND DNS server is located at /etc/named.conf. You can open this file using a text editor like vim or nano.
Step 3: Add the DNS record
Now that you have opened the configuration file, the next step is to add the DNS record. There are different types of DNS records, but we will focus on the most common one, which is the A record. The A record maps a domain name to an IP address. To add an A record, you need to add the following lines to the configuration file:
zone "example.com" {
type master;
file "/var/named/example.com.zone";
};
Replace "example.com" with your domain name, and "/var/named/example.com.zone" with the path to your zone file. Now that you have added the zone configuration, you can add the A record. To add the A record, add the following lines to your zone file:
@ IN A 192.168.1.10
Replace "192.168.1.10" with the IP address of your server. The "@" symbol represents the domain name itself.
Step 4: Restart your DNS server
Once you have added the DNS record, the final step is to restart your DNS server. You can do this by running the following command:
systemctl restart named
This will restart the BIND DNS server, and your new DNS record will be live.
More Examples:
In addition to the A record, there are other types of DNS records that you can add to your DNS server, such as:
- CNAME record: maps a domain name to another domain name.
- MX record: maps a domain name to a mail server.
- TXT record: adds text information to your DNS record.
To add these types of DNS records, you can follow a similar process as we outlined for the A record.
Adding a DNS record to your DNS server is a straightforward process. By following the steps we have outlined in this article, you can add an A record to your DNS server, which maps your domain name to an IP address.
