Which DDNS Provider Works For You?

Hi,

I have been struggling to find a DDNS provider from which the IP address can be updated from a Cisco device.

One does not seem to support it, (Free-DDNS) other must be paid for (No-IP.org) while the free version does not update the IP address in my case, etc, etc.

The device that is directly behind my modem is a Cisco 1801 router.

My question is, which DDNS provider works for you when auto-updating the IP address via the Cisco router?

Grtz, Dominic

with IOS version 12.4 (and some versions of 12.3), DDNS is now available in the Cisco IOS.

How to configure DDNS varies based on the DDNS service you choose. The  IOS supports two methods for performing DDNS updates: the popular  generic HTTP and the IETF standard based on RFC 2136.

Cisco offers sample configuration strings for the following 7 DDNS services that use HTTP as an update method:

  • DDNS
  • TZO
  • EASYDNS
  • JUSTLINUX
  • DYNS
  • HN
  • ZONEEDIT

If you don’t have a DDNS service already, I would recommend choosing  one of these, or choose one that offers their own instructions for  configuring DDNS on a Cisco router, such as these configurations for the Cisco IOS DDNS service from no-ip.com.
