As of 27th September 2026, AS20055 (Ziply Fiber), an access network registered in the United States with ARIN, originates 59 IPv4 prefixes covering 955k addresses and 6 IPv6 prefixes. By IPv4 address space that makes it the 477th-largest of the 79,523 networks we see originating IPv4, and the 112th-largest of 18,427 in the United States. It is seen behind 16 upstream networks, most often AS6461 (Zayo Bandwidth) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 126 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.

Upstream graph

The networks AS20055 is seen behind, one and two hops out, drawn from real AS paths.

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.
