Networks this one appears to provide transit to
| Network | Country | Cone | IPv4 prefixes | Paths | Source |
|---|---|---|---|---|---|
| AS24490 Trans-Eurasia Information Network (TEIN2) - SG | 🇨🇳 CN | 1,339 | 1 | 66 | 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.
