Summary

Janet (Jisc)

United Kingdom · AI-generated

education research nren legacy

Janet, the United Kingdom's national research-and-education network, operated by Jisc. It provides the backbone connecting UK universities, colleges, and research councils.

What it's used for

  • Connecting UK higher and further education institutions and research bodies to each other and to international research networks.

Notable

  • An IP here is institutional/research — a national NREN backbone linking member campuses and labs, classified education rather than commercial hosting.

Interesting

  • A low AS number reflects Janet's long history; it has been the UK's academic network since the 1980s.

Education University, school or national research and education network.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
