| AS15535 Virtual Access Internet BV | 🇳🇱 NL | 0 | 1 | 41 | 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.
