Summary

NorrNod, Umeå University

Sweden · AI-generated

education university research

A Swedish university's regional network holding two /17s, reached through a single upstream.

What it's used for

  • Academic and regional network access. 90,112 addresses across four IPv4 prefixes, no IPv6 announced, and one observed BGP neighbour.

Notable

  • The four blocks are two /17s, a /18 and a /19 — 90,112 addresses answering for one university's computing centre.
  • Two of them, 212.32.128.0/18 and 194.165.224.0/19, carry the same netname SE-UMDAC-960209: one date, two separate allocations.
  • The other two are SE-UMDAC-990914 and SE-UMDAC-20010918, the later one with the year spelled in full.
  • Every block is registered to NorrNod at UMDAC, Umeå University, and the AS handle reads NORRNOD ITS.
  • First seen in routing data in June 2002.

Interesting

  • The network and the operator are named separately in every record. NorrNod is the network, UMDAC is the department that runs it, and the registry keeps both. Swedish academic computing was built around regional centres rather than per-campus networks, and it is the region's name that ended up on the paperwork.
  • Ninety thousand addresses reached through one neighbour is the shape of a network that serves a territory rather than a campus. The address count says how much space it holds; the single neighbour says it is somewhere at the edge, not carrying anyone else's traffic.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
