As of 23rd October 2026, AS786 (Jisc Services Limited), an access network registered in the United Kingdom with RIPE NCC, originates 210 IPv4 prefixes covering 7M addresses and 7 IPv6 prefixes. By IPv4 address space that makes it the 108th-largest of the 79,659 networks we see originating IPv4, and the 4th-largest of 2,077 in the United Kingdom. It is seen behind 31 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS3356 (Lumen (Level 3)), and in front of 25 downstream networks. 40% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS786 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.
