AS142240HostNost
BangladeshRegistryAPNICAs of 11th November 2026, AS142240 (HostNost), a network registered in Bangladesh with APNIC, originates 20 IPv4 prefixes covering 5.1k addresses. By IPv4 address space that makes it the 15,570th-largest of the 80,743 networks we see originating IPv4, and the 95th-largest of 1,567 in Bangladesh. It is seen behind 2 upstream networks, most often AS63199 (CDS Global Cloud Co., Ltd) and AS265137 (CONECTIVA TELECOM TECNOLOGIA LTDA - ME). None of its announcements have a valid RPKI ROA; 10 are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph
The networks AS142240 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS142240 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.
