DNS i.e., the Domain Name Server also known as Domain Name System is the hierarchical and decentralized system of identifying systems reachable through the Internet Protocol networks.
It works by looking up your website by finding its domain name and then locating its associated IP address. Whereas, the reverse DNS first looks up for an IP address and then locates the associated domain name.
At SANGKRIT.net, you can easily set up a reverse DNS (rDNS) lookup for your Dedicated Server. To start, simply login to your SANGKRIT.net account and follow these steps:
- Visit your My Products page
- Click Servers
- Next to your server, click Manage
- Enter the domain name you want to be associated with the server IP address, in the DNS record field
- Now click Update
The system will start an automated process of completing the reverse DNS setup. This can take up to 48 hours for the changes to propagate to your server.
You should also know that, when you run your own email server, and configure DNS to point to your domain name, there are some servers that are going to reject emails from IP addresses when not having an rDNS. The reverse DNS also helps when you need to troubleshoot your network while running a traceroute etc.
