Re: revised ACL 112 ?
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.
