| AS63363 Tucows.com Co. | 🇨🇦 CA | 0 | 2 | 40 | inferred |
| AS393818 Tucows.com Co. | 🇨🇦 CA | 0 | 2 | 1 | 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.
