[This is about ARIN, but curious to see if anybody has any insight...]
A colleague of mine showed me
https://whois.arin.net/rest/net/NET6-2630-2, i.e., a /16 allocated by ARIN to Capital One (AFAIK a US bank).
Of course, this may be a tool bug, or a human encoding mistake, else I will start to fear an IPv6 addresses exhaustion in the future (only 2**13 of /16 out of 2000::/3).
If anyone has any insight, then I will welcome this insight in this specific case.
Regards
