RE: Register.com .....routing issue?

I believe Register.com (or any for that matter) has the right to use
internal address space where ever they want. The fact that internal address
space is showing in a traceroute between you and them might mean a wide
range of things.

In this case, Register.com 'might' be using internal address space on
some(all) of their WAN links.

You <-> Internet <-> Company A Router <-> WAN Link (internal IP space) <->
Company A Router <-> Web Servers

Whether or not people should used RFC reserved IP space for WAN links is not
a discussion I wish to have.

Hey folks,

        Has anyone tried to trace to Register.com's main page yet?  I
haven't been able to hit it, and when I try to trace down to them I end up
hitting a 10.0.30.x network, then go back to public IP's...how is that
possible?

        Anyone else having trouble connecting to them?

Happy Monday! (still)
