The Domain Name System (DNS) is a database of Internet host names with their
corresponding IP addresses distributed over designated DNS servers. It enables
network users to refer to hosts by name, rather than by IP addresses, which are
harder to remember. Use this window to enable the use of DNS servers for host
name to address translation.
Check this box to enable the router to use the DNS. Uncheck this box if you do
not want to use the DNS.
Enter the IP addresses of the DNS servers that you want the router to send DNS
requests to.
Click the Add, Edit, and Delete buttons to administer DNS IP address
information.
This window shows a list of dynamic DNS methods.
Each dynamic DNS method shown will send with its update the host name and
domain name configured in Configure > Additional Tasks > Router Properties.
However, if you create a dynamic DNS method when configuring a WAN
interface, you can override the host name and domain name configured in
Configure > Additional Tasks > Router Properties. The new host name and
domain name will apply only to that dynamic DNS method.
Some dynamic DNS methods are read-only. These were configured in the Cisco
IOS software through the CLI, and cannot be edited or deleted. To make these
read-only methods editable, use the CLI to change the internal cache or host group
options to HTTP or IETF.
Click the Add button to create a new dynamic DNS method.
