Number of 6to4 gateway in the globe

I got a list of 33 ASNs that advertize the anycast Class C range 192.88.99.0/24 in their BGP routes:


AS59, AS559, AS680, AS1103, AS1239, AS1257, AS1299, AS1835, AS1930, AS2018, AS2116, AS4621, AS6939, AS7575, AS8359, AS8473, AS12573, AS12779, AS12871, AS15598, AS16150, AS19255, AS19782, AS20312, AS20640, AS25192, AS28917, AS35244, AS38646, AS39326, AS39556, AS44581, AS55374

Some people just wonder why I am interested in tracking the number of ASNs that handle 192.88.99.0/24.  It is because the anycast address 192.88.99.1 is assigned to 6to4 relay.  In other words, there are now 33 service providers that offer free 6to4 gateway service.  Well, this is a thriving development.  They are helping the transition to IPv6 for clients using 6to4 tunnels.

Well-done !
