AS64728
As of 10th November 2026, AS64728 originates 4 IPv4 prefixes covering 1k addresses. By IPv4 address space that makes it the 36,486th-largest of the 80,723 networks we see originating IPv4. It is seen behind 1 upstream network, most often AS40169 (USABROAD INC.). None of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 4 prefixes are also originated by another network.

Upstream graph
The networks AS64728 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS64728 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.
