Imho, an application doing this is fundamentally broken.  One day this
will come back to bite, especially under IPv6.  I believe that avoiding
renumbering to cater for apps that did the wrong thing in the first place
would be a big mistake.  Besides, dns data is cached, so the first lookup
might be slower but the rest should come off a local dns server.
