You might want to set this in your ssh configuration.  It will avoid
logging the IP address in the ssh known hosts file subsequently.  If
the IP address is not important then this is a good solution.

  CheckHostIP no

And you can set that on a host by host basis with wildcards.

  Host *.example.com
    CheckHostIP no

In OpenSSH the _first_ configuration matched for an item wins.
