education residential university sweden

The AS handle UPPSALA-STUDENT-NETWORK is held by Uppsala Student Network.

What it's used for

  • The space carries student network access, evidenced by the netname UpUnet-S and reverse DNS entries like nl119-107-254.student.uu.se.
  • The AS announces 40,448 IPv4 addresses across 5 prefixes with only 1 observed neighbour, a ratio indicating an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of student internet access, including Wi-Fi and wired connections for Uppsala University students.

Notable

  • Registrants for the majority of prefixes are Uppsala Student Network, while the prefix 212.25.130.0/23 is registered to IRT-SUNET-CERT with netname SE-SUNET-20100527, indicating space allocated by the Swedish university network.

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: 440 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.
