That sure looks like DNS trouble.

Try doing "ping -n" and see if the apparent delays go away.  If they do,
then that's the problem: your RFC 1918 addresses aren't being resolved
properly back in to host names, and that's causing ping to get hung up.

A "simple" fix is to run a caching DNS server, and map the
168.192.in-addr.arpa domain into your own local set of definitions.

The good news is that it doesn't represent any sort of real performance
problem.  ;-}
