Also, going out of Exetel. .104 hits an extra Exetel address. They all seem to converge upstream at Lvel3.net with some differences.
What is that hostdime.com host that pops up in 104 trace and is absent in others?

Hi Danny,
I am on an Exetel link and my traceroute shows some very different routes for the 104 as opposed to the 103 & 105. Something IS going on! I can get to port 80 on 103 & 105 but not 104. Typical of the "we know what's best for you and you don't need to be told the details" attitude of our government.
