2610:1c1::/32 not reachable from AS3320 (Deutsche Telekom)

Hi,

it seems Deutsche Telekom AS3320 are not accepting 2610:1c1::/32 altough they do accept 2610:1c0::/32.

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.

Greetings
Christian
