Greetings.
I was hoping someone could point me in the direction of provider/NAP
prefix filtering policies. Most important to me is UU and Cogent, but a
concise listing of notables would be much appreciated.
Regards,

Just to clarify, NAPs or Internet exchanges are typically (like more than
99% of the time) layer-2 services, which don't pay attention to or care
about layer-3 things like IP prefixes. A few have policies regarding what
participants should filter on their own behalf, but of the four hundered
odd exchanges currently operating out there, I don't know of any which
filter prefixes themselves.
Virtually all _providers_ over a certain size filter heavily, of course,
and that's probably the portion of your question you'll get more (and more
useful) answers to.
