turn off reverse mapping checking?

I now have a new ISP and when I ssh into my home computer I'm getting
this message:

reverse mapping checking getaddrinfo for <domain name>
[<IP address>] failed - POSSIBLE BREAK-IN ATTEMPT!

It's not a big deal but can the messages be turned off? I've tried

StrictHostKeyChecking no
CheckHostIP no
VerifyHostKeyDNS no

in /etc/ssh/ssh_config and

UseDNS no

in /etc/ssh/sshd_config (on the remote system).

Re-starting sshd with option -u0 is supposed to do this, but it doesn't
work for me. A simple brute-force solution is to use (a script that does)

ssh host 2> /dev/null
