If you are using the OpenSSH daemon on the remote server and that 
daemon is using the default configuration, it does a reverse DNS 
lookup on the connecting IP before accepting the login.

IIRC, It is possible to disable this reverse DNS lookup in the 
OpenSSH daemon configuration.  It is not possible to disable this 
lookup by adjusting the client configuration or version.

In general, you should make sure reverse DNS works for all your IPs.
