Hi, it seems Deutsche Telekom AS3320 are not accepting 2610:1c1::/32 altough they do accept 2610:1c0::/32. https://f-lga1.f.de.net.dtag.de/index.php?pageid=lg&query=ipv6+bgp¶=2610%3A1c0%3A%3A%2F32&server=194.25.0.218&EXEC=Execute https://f-lga1.f.de.net.dtag.de/index.php?pageid=lg&query=ipv6+bgp¶=2610%3A1c1%3A%3A%2F32&server=194.25.0.218&EXEC=Execute we opened a case with AS3320 as a customer because we cannot reach svn0.us-east.freebsd.org because of this. They claim the network is not documented properly in the routing registries which is why they cannot accept the prefix. I am no expert on routing in the ARIN region. Could anybody of you guys have a look at the specific network: The New York Internet Company NYNET22 (NET6-2610-1C0-1) 2610:1C0:: - 2610:1C2:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF and let me know if you see anything obviously wrong. I am trying to get this resolved as a customer of AS3320.
