Gave this a go myself...
$ ./python

According to strace, both rely on DNS:
recvfrom(3, "Wj\201\200\0\1\0\1\0\5\0\0\00219\003134\003230\003173\7in-a"...,
1024, 0, {sa_family=AF_INET, sin_port=htons(53),
sin_addr=inet_addr("1.2.3.4")}, [16]) = 176
Same behavior on both 2.6 & hg tip. I think this is a non-issue.
