For the first time we have had to deal with Sprint's routing policy as defined by http://www.sprint.net/filter.htm. 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.

I am now in the position trying to explain to the very non-technical customer, why he cant reach that site, which from his point of view just seems like I am passing the buck...
Anyways, my question is, are their any other ISPs/NSPs that follow the same guidelines. UUNet seems to honor it just fine, as does MCI. Is Sprint more hardnosed than most ?
