Anyways to address the actual question: I haven't dealt with anyone other than Sprint filtering space longer than /19 in the 206.0.0.0/8 but in the past I had issues with both UUnet and Agis filtering errant /24's and /23's out of 204.0.0.0/8. I've been very clearly telling all my customers that while I will route their IP space for them, as long as its allocated to them - I will not be responsible for anything that we know Sprint may or may not filter on any given day. It generally works well, they take space from me and we resubmit their space to whomever the governing body is/was at the time. For customers that really have a need we push as hard as we can to get them their own /19 so they'll not have to renumber but we know the issues involved with this. jlw On Wed, 6 May 1998, Bryan Fullerton wrote:

Here is the situation. One of our dialup customers wants to access his website in the 206.116.31.0/24 network at another provider. PSI is advertising it as a /24. According to Sprint's routing policy, they do not honour anything longer than a /19 in 206.0.0.0/8 .It's interesting that PSI routes it at all. While IP ownership (note the NON-PORTABLE below) and routing aren't necessarily interconnected, I suggest contacting the block's owner and seeing if they know it's alternately routed. If they wish, they can request that PSI un-route this block. However, that would break whomever is using it. The user should re-number into PSI space, and this issue will go away. If the user is multi-homed, they should investigate the adivisibility of getting a CIDR block which they can announce as an aggregate. My $0.02 ___ iSTAR Internet Inc. (NETBLK-ISTAR0005) 250 Albert Street, Suite 202 Ottawa, Ontario K1P 6M1 Canada[snip] PSI bought iSTAR earlier this year, so it's not really surprising that they're routing these networks.
