Hi Konstantin, A quick cross-check on RIPEstat (https://stat.ripe.net/widget/asn-neighbours#w.resource=AS49505) shows that the peering between Selectel (AS49505) and Transtelecom (AS20485) is IPv4 only. So if you are in AS20485 you might not even see the Selectel K-root node via IPv6. Kind regards, Romeo
