Summary

Sweden · AI-generated

education research legacy

The network of Luleå University of Technology (LTUNET, Luleå tekniska universitet), a public research university in Norrbotten in northern Sweden.

What it's used for

  • Campus, research, and administrative networking, connected through SUNET, the Swedish University Network.

Notable

  • An institutional/education network, not commercial hosting. The low AS number reflects an early SUNET-era allocation.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
