In other news, I recently hacked Firefox to refrain from looking up the PTR records for every IP which it connects. I commented out the AI_CANONNAME flag in the hints that were passed to getaddrinfo() in the nspr resolver library. If you want to hack this yourself, look at line 2085 of nsprpub/pr/src/misc/prnetdb.c in the source tree.
