I have installed ddclient on my server and it seems to work. However, I get these warnings in my syslog:

nochg: No update required; unnecessary attempts to change to the current address are considered abusive

Obviously, ddclient fires the update even if the IP address check returns the same address as last time. How can I change this to have it do the update only if the address has actually changed since the last run?

Here is my /etc/ddclient.conf, with some information redacted:

use=web,, web-skip='Current IP Address:'
