Thanks, Jeff; this is very helpful.

I'm assuming something like this is where I need to go to get my own AS number?

FYI, here's a list of BGP links for those interested.

Outgoing is easy, so I presume you're writing about having incoming traffic flow.

Generally for this to work you have to have your own assigned IP# blocks. Though I believe it can be done if you're relying on IP#s from your carriers, I'm not sure if you can get the carriers to let you do the routing on IP#s they're supplying.

And that's the key.

You'll need to use BGP to create and advertise routes for those IP#s. I don't know which routers do that, because I've never had to do it and I've never checked, but in general they're expensive routers.

The best list for asking these kinds of questions has, in the past, always been "the list":
