ChinaRegistryAPNIC

As of 11th November 2026, AS63727 (Huawei), a network registered in China with APNIC, originates 5 IPv4 prefixes covering 6.4k addresses. By IPv4 address space that makes it the 13,908th-largest of the 80,743 networks we see originating IPv4, and the 285th-largest of 617 in China. It is seen behind 2 upstream networks, most often AS9808 (China Mobile Backbone) and AS4808 (China Unicom Beijing Province Network). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 4 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS63727 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.
