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.

PSI bought iSTAR earlier this year, so it's not really surprising that
they're routing these networks.
