This is what we are currently seeing. Unfortunately @Home does not do
reverse dns for their routers so I am going by their helpdesk's descriptions
of locations. I do know that the router is in SF but could not get an exact
location due to @home claiming it to be a sprint issue. This also brings
back the conversation of RFC1918 addressing and the problems it can cause
when troubleshooting response issues.
I haven't actually tried this, but I have been told that if you actually
use @Home's DNS servers and query the RFC1918 addresses for the routers, it
will give you back "intelligent" names.
