Summary
SUNET (Swedish University Network)
education research legacy
SUNET, the Swedish University Computer Network (SUNET), is Sweden's national research and education network (NREN), connecting the country's universities and research institutions.
What it's used for
- High-capacity networking for Swedish universities, colleges, and research organizations.
Notable
- A national research/education backbone, not a commercial ISP. It holds a large block of IPv4 address space serving the Swedish academic community.
- The low AS number reflects an early allocation from the internet's first years.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
