As of 11th November 2026, AS7438 (PEGASO PCS), an access network registered in Mexico with LACNIC, originates 145 IPv4 prefixes covering 168k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 1,558th-largest of the 80,743 networks we see originating IPv4, and the 15th-largest of 502 in Mexico. It is seen behind 3 upstream networks, most often AS12956 (Telxius (Telefonica Global)) and AS32098 (Flō Networks (Transtelco Inc.)), and in front of 8 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 92% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS7438 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.
