As of 10th November 2026, AS63752 (Department of Science and Technology of…), a network registered in Vietnam with APNIC, originates 1 IPv4 prefix covering 1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 36,486th-largest of the 80,723 networks we see originating IPv4, and the 184th-largest of 537 in Vietnam. It is seen behind 1 upstream network, most often AS45899 (VNPT Corp). 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, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS63752 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.
