Reverse dns is not updating

DNS is known to most Internet users for translating hostnames into IP addresses (called forward resolution).An example of this is entering the browser and receiving an IP address for the server dedicated to that website.First, you have to configure your zone for reverse DNS.Second, you have to request reverse delegation of your zone.The process of acquiring reverse resolution is accomplished using PTR records that are rooted in the domain.

Because of the shared nature of the Grid, the reverse DNS record for the server is already set.A lesser-known task that DNS performs is determining the hostname from an IPv4 address, commonly called reverse resolution.This is normally used by servers to find the human-friendly name associated with the IP address.For your domains, standard DNS (turning a hostname into an IP address, such as turning host.into 192.0.2.25) starts with the company (registrar) that you registered your domains with.You let them know what DNS servers are responsible for your domain names, and the registrar sends this information to the root servers (technically, the parent servers for your TLD).

The second part is done by creating a domain object in the RIPE Database.
