IndiaRegistryAPNIC

As of 10th November 2026, AS148003 (National Knowledge Network), a network registered in India with APNIC, originates 2 IPv4 prefixes covering 512 addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 49,308th-largest of the 80,723 networks we see originating IPv4, and the 1,436th-largest of 2,966 in India. It is seen behind 1 upstream network, most often AS4755 (TATA Communications (formerly VSNL)), and in front of 1 downstream network. 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 AS148003 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.
