Hello Routing Working Group,

The following questions came up in the routing working group slack and I am seeking volunteers to participate in this discussion from FITI/CERNET/Tshinghau.

Did ~ 4000 of the ASNs and IPv6 prefixes that are part of / behind AS3825 (Exchange Centre of FITI) go away more than a day ago? It looks like there were separate ASN for each IPv6 prefix, AS142650 to AS146745. There are now only 43 Prefixes behind AS38255.

`

Should we expect to see the 4000+ IPv6 prefixes to come back or not?

We appreciate any insight the routing working group can provide into this

Thank you!
