Dynamic DNS in Cisco IOS

September 25, 2009 Comments

Dynamic DNS support was introduced in IOS version 12.3(8)YA. I recently started using this service with my DynDNS account and thought it might be useful to provide a short tutorial for myself and others to refer back to. It goes without saying that you will need an active DynDNS membership for this to work.

Begin by logging into your router via SSH, telnet, management console or what have you. Go into enable mode and proceed to the global configuration (conf t).

Enable the DDNS service:

ip ddns update method ddns

You will then be in the DDNS configuration. Enter the following statements, replacing the obvious variables with your own information. Be sure to press Ctrl-V prior to typing ? in the command line. If you don't, you will be prompted with IOS context-sensitive help information.

HTTP
 add http://USER:PASS@members.dyndns.org/nic/update?system=dyndns&hostname=HOST&myip=<a>
interval maximum 1 0 0 0

When you are finished, exit out of the DDNS configuration and go into the WAN interfaces configuration (int <interface>). Enter the following:

ip ddns update ddns

And there you have it. The router should now automatically update your DynDNS host when needed. Don't forget to save your changes (wr).

Finally got my hands on some good tea

My British coworker, Lee, was generous enough to send me tea from the UK. I offered to repay him with some quality Lipton, but he respectfully declined.

I finally found a place around here at carries Mexican Coca Cola. It's not too bad, but I don't see myself making a habit of drinking it that often.
