Hi, It seems the Swiss POP for sixxs (IPv6 connectivity) is unreachable from Cablecom (net2000), Sunrise ADSL, Bluewin ADSL, but is reachable from Green ADSL.
For the records, http://www.sixxs.net/) is where you can get free IPv6 on IPv4 tunnels when your ISP hasn't yet arranged for IPv6 end-user delivery (most don't). It used to be reachable in november 2009 when I did my last tests, on Cablecom (net2000). The IP address of the POP is: 194.1.163.40 Looks like this is a /24 (PI) within IP-MAN's AS. Does anyone has an idea why it is not routed correctly ? (SIXXS is working on it, however, what's behind the scene interests me). Is this because it's a lone /24, and most providers don't peer correctly for less than /22 ? An administrative problem (like when EUnet was routed through Amsterdam for SWITCH customers -- well at least it was routed!) Or is it because IP-MAN wants direct peering and doesn't announce the prefix globally ? Maybe to avoid being charged by strange peering plans ? Thanks ;) have a nice new year 2010! PS: I am especially interested because I am considering to route a old /24 from a /15 (allocation unspecified) somehow, and want to see if it is really usually unfeasible from a global routing perspective, or from the practical quirks of commercial operators today. _______________________________________________ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
