| Network | Country | Cone | IPv4 prefixes | Paths | Source |
|---|---|---|---|---|---|
| AS39832 Opera Norway AS | 🇳🇴 NO | 2 | 16 | 83 | CAIDA |
Relationships marked inferred come from where the two networks sit on the AS paths the collectors see, which is a guess and is wrong for some of them. The rest are stated by CAIDA's published inference over a much wider set of collectors.
