IP Address
Choose how the router will obtain an IP address for this link.
•Static IP address—If you choose Static IP Address, enter the IP address and
subnet mask or network bits in the fields provided. For more information, see
IP Addresses and Subnet Masks.
•Dynamic IP address—If you choose Dynamic, the router will lease an IP
address from a remote DHCP server. Then enter the name or IP address of the
DHCP server.
Hostname
If your service provider inserts a hostname for the router into the DHCP response
that contains the dynamic IP address, you can enter that name in this field for
informational purposes.
Dynamic DNS
Enable dynamic DNS if you want to update your DNS servers automatically
whenever the WAN interface IP address changes.
Note This feature appears only if supported by the Cisco IOS release on your router.
To choose a dynamic DNS method to use, do one of the following:
•Enter the name of an existing dynamic DNS method.
Enter the name in the Dynamic DNS Method field exactly as it appears in the
list in Configure > Additional Tasks > Dynamic DNS Methods.
•Choose an existing dynamic DNS method from a list.
Click the drop-down menu and choose an existing method. A window with a
list of existing dynamic DNS methods opens. This menu choice is available
only if there are existing dynamic DNS methods.
•Create a new dynamic DNS method.
