Not at all. My traceroute results don't even hit the same Class-A block
as the origin of the rewritten DNS requests. My workstation is on
Verizon DSL, and my server is with DCA (both in Philly). However, an
arin.net reverse lookup of the IP of packet origin reveals that the
particular block of IPs is owned by a telecom company in Taiwan.
Indeed, this makes things even more strange.
