My understanding from Cogent (our upstream provider)
is we provide them with a letter from ARDC allowing us to advertise the sub net to the
other AS machines around the world. They put the sub net in their AS then magic of the
Internet it routs to our server/users. I am not a Computer Science major or person so I
am just learing how things work up stream from the ISPs. So correct me if I am wrong.
Tim the reason for not doing IP tunnels is easy. Single point of failure. God forbid
SCSD drops in to the ocean (not really but lets just say the big one hits SoCal) all of
AMPR is down.
Of course. If you check out my previous email and were a fly on the wall when I phoned
Brian some months back, I have always been a proponent of having 44 address space being
announced at other places beyond UCSD for all the reasons we have chatted about.
As for announing the some prefix of 44/8, good to see your upstream asking for some
authority before they would pass that announcement. It definitely needs to be a
requirement that it comes from ARDC and shows the prefix. It should also be some
requirement that this shows up in a Routing Registries (ie. Altdb, Radb, etc.)
