Agreed… Unforutnately, the big guys (Comcast, AT&T) in America seem to like victimizing their customers with undersized assignments, limiting choice of proper prefix sizes to only their business class customers. I’m not sure why they are doing this. I know when I’ve had conversations with them, they haven’t exactly given a reason so much as just said that they thought a /48 was ridiculous.

Of course, if AT&T is blocking protocol 41, that’s even worse, because at least so long as that isn’t blocked, you can still get an HE tunnel and get a /48 if you need it anyway.
