| AS24406 China Internet Network Infomation Center | 🇨🇳 CN | 0 | 28 | 387 | CAIDA |
| AS3557 ISC - F-root | 🇺🇸 US | 0 | 2 | 16 | 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.
