| AS1848 National Aeronautics and Space Administration | 🇺🇸 US | 0 | 25 | 37 | 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.
