Dynamic DNS
When you want your internal server to be accessed by using DNS name rather than using the dynamic IP address,
you can use the DDNS service. The DDNS server allows to alias a dynamic IP address to a static hostname.
This chapter provides you an overview of the Dynamic DNS feature of the modem and conguration details rela-
ted to it.
Overview
If some host has a dynamic IP address that keeps changing frequently, it is dicult to keep updating the IP record
that is associated with the domain name of this host in the zone les. This will result in non-accessibility of this host
on the Internet. Dynamic DNS service allows to keep mapping of a dynamic IP address of such host to a static host-
name. Dynamic DNS services are provided by many websites. The host needs to register with some website and
get a domain name. When the IP address of the host changes, it just needs to send a message to the website that’s
providing dynamic DNS service to this host. For this to work, an automated update client needs to be implemented.
These update clients send update messages to the servers whenever there is some change in the IP address of that
host. Then, the server updates the entries for that host and replies back with some return code.
