Sprint Filters - what are they?

A while ago we had a customer with some routing problems which were caused by Sprint filters (127/8 - 191/8, deny anything longer than /16). When customer called Sprint, he's been told by someone from tech support that 'Sprint doesn't filter anything'. When I called support, I've been told that on 127/8 - 191/8 range Sprint denies anything longer than /16. This morning the same customer called Sprint again, to confirm this information, and been told that for the above range Sprint denies anything longer than /19. It seems like each time you call Sprint support, you hear a different story. Will someone from Sprint _who knows_ confirm their filtering policy which I have as follows: 0/8 - 126/8, deny subnets of historical A's 127/8 - 191/8, deny anything longer than /16 192/8 - 205/8, deny anything longer than /24 206/8 - 223/8, dney anything longer than /19 192/8 [RIPE], deny anything longer than /19 It would be really nice to have it posted at NANOG web page as well (alas, only AGIS done so). Thanks, - Greg - - - - - - - - - - - - - - - - - -
