Filter out any /24 - /32 announcement you hear from above.net.
It's ugly but will help keep the route out of your table.
From what I understand of this silly business, the /32 blackhole route
isn't being advertised by Abovenet and so isn't in the local table at all. The /16 being propagated IS, however, and traffic for that host is following that route via his Abovenet upstream connection (at which point it's then discarded within Abovenet's network). I wasn't aware Abovenet were forcing anyone to buy transit from then, or forcing any of their downstreams to not use filters to block that particular /16 announcement - is there something in the T&Cs I've not noticed?? Of course, if Abovenet's policy is so abhorrent, I'm sure when they lose their last paying transit customer they'll wake up to their longtime folly ;) -- Patrick Evans - Net bloke, indie kid and lemonade drinker pre at pre dot org www dot pre dot org
