Networks this one appears to provide transit to
| Network | Country | Cone | IPv4 prefixes | Paths | Source |
|---|---|---|---|---|---|
| AS2698 Iowa State University of Science and Technology | 🇺🇸 US | 4 | 7 | 147 | CAIDA |
| AS393308 City of Iowa City | 🇺🇸 US | 0 | 1 | 2 | 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.
