It's your contention that Abovenet shouldn't announce 194.178.0.0/16 just because they are NULL routing 194.178.232.55/32 for policy reasons? You ARE confused, aren't you?
If I receive a route from someone I presume that the whole block being announced for transit is going to be reachable, unless the actual owner of the block thinks and does otherwise. This presumtion is obviously wrong in above.net:s case, but the only way to make above.net stop doing this is obviously to stop being the customer of above.net, or stop being the customer of a customer of above.net. An interesting question is whether above.net only nullroutes 194.178.232.55/32, or do they filter packets coming FROM this IP as well, going to other destinations? That would be worse in my book. I can choose to not send my packets going to 194.178.232.55/32 thru above.net, but I have much less power in whether packets coming from 194.178.232.55/32 to my network transits above.net:s network. Personally I believe that vuurwerk.nl should ask UUNET (their upstream) top stop announcing their netblock to above, or at least prepend it a lot. That would stop above.net from transiting that /16 more than absolutely neccessary. -- Mikael Abrahamsson email: swmike () swm pp se
