As of 23rd October 2026, AS903 (Unified Communications Technologies, LLC), a network registered in the United States with ARIN, originates 18 IPv4 prefixes covering 7.4k addresses. By IPv4 address space that makes it the 12,866th-largest of the 79,658 networks we see originating IPv4, and the 3,766th-largest of 18,483 in the United States. It is seen behind 2 upstream networks, most often AS36295 (Florida High Speed Internet) and AS13760 (Uniti Fiber Holdings Inc.). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS903 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.
