Why not? 0.209.226.130.in-addr.arpa is delegated, all of the
*.209.226.130.in-addr.arpa aliases, from 1 through 126, point into that
delegated zone. Sure, it doesn't follow the usual RFC 2317-inspired naming
conventions, but it should still work.

I think the real problem is the one I identified earlier, i.e. a stale
slave for 226.130.in-addr.arpa.
