As of 28th September 2026, AS3681 (Florida International University), a network registered in the United States with ARIN, originates 6 IPv4 prefixes covering 68.4k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 3,199th-largest of the 79,544 networks we see originating IPv4, and the 1,055th-largest of 18,428 in the United States. It is seen behind 3 upstream networks, most often AS20080 (Florida International University) and AS36843 (Florida State University). None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS3681 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
