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.)
