As of 11th November 2026, AS20055 (Ziply Fiber), an access network registered in the United States with ARIN, originates 61 IPv4 prefixes covering 974k addresses and 6 IPv6 prefixes. By IPv4 address space that makes it the 475th-largest of the 80,747 networks we see originating IPv4, and the 111th-largest of 18,752 in the United States. It is seen behind 15 upstream networks, most often AS6461 (Zayo Bandwidth) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 134 downstream networks. 94% of its announcements have 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 AS20055 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.
