Updating ddns status
If you do a DNS query for the hostname, you will get the IP address back that you entered.
The last step is to make sure that your hostname always matches your IP address as it changes.
In Figure 4-10, Router can function as a web server to provide web services for network users and users can access the web server by sending DNS requests.
The domain name of the web server is com, corresponding to the IP address of GE1/0/0 on Router. As a result, if the mapping relationship between the web server's domain name and the IP address is not updated in time on the DNS server, a user access error may occur.
This chapter is a guide on configuring a provider DDNS instance on RUT routers.

Your router has an update client that monitors your IP address and will update the hostname should the IP address change.
