Introduction to DNS and RevDNS

Computers communicate in binary, using zeros and ones. The IP address is this binary number assigned to each machine in a network - it is usually written in decimal form for convenience.

However, when we connect to websites, we type their names, not their IP addresses.

This is made possible by the DNS (Domain Name System) service, which translates domain names into IP addresses. When you enter a domain name, the computer determines the IP address of the server using DNS servers nad connects to it. Without the DNS system, we would type IP addresses instead of domain names.

An example of this system's operation is translating the Skynode.eu domain to the 149.86.224.18 IP address.

Knowing what this service is, you can define RevDNS - reverse DNS also called a PTR record. Its purpose is to translate a domain address into an IP address. It means that you can find the domain name of an IP address - for example, find out that the domain name of 149.86.224.18 is Skynode.eu.

To sum up, the DNS can be compared to the contact book on your phone - you search for the name of a contact to call a specific number. RevDNS can be compared to a situation, when your phone shows you the name assigned to a calling number.

Every IP address you own in Mevspace servers can have RevDNS assigned to it, using a convenient feature in the panel. Log in, go to server view, click the three dots next to the IP address, then select Change RevDNS and enter the domain address of your choice.
