PakistanRegistryAPNIC

As of 26th September 2026, AS133551 (OriginNet), a network registered in Pakistan with APNIC, originates 11 IPv4 prefixes covering 2.8k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 22,343rd-largest of the 79,516 networks we see originating IPv4, and the 71st-largest of 302 in Pakistan. It is seen behind 2 upstream networks, most often AS38193 (Transworld Associates (Pvt.) Ltd.) and AS24499 (Telenor Pakistan). 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 AS133551 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.
