In February we received a new /20 CIDR from ARIN. I felt that we might be
caught by the filters at ISPs like Sprint (http://www.sprint.net/filter.htm).
I contacted Sprint twice and spoke to two different engineers, both told
me that they were not filtering as their page described, and they would
allow advertisements for /20 in 206/8 - 233/8. Since that time I have
spoken to several people who purchase transit from Sprint, and they do
indeed see my advertisements. Looking at NetFlow stats I can't find any
major provider that we have not had traffic flow between. I assume they
had to have accepted my advertisements, nobody runs BGP and default routes
:).
BTW: I also contacted, and received a similar response from ANS.
