Summary

hosting datacenter nsp
ITSJEFEN-AS is operated by ITsjefen AS.
What it's used for
- The address space carries data center and hosting infrastructure, evidenced by reverse DNS entries such as
vdc-ndc.trd.no.as44381.netander4.ndc4.trd.as44381.net, which reference virtual data centers and edge routers in Trondheim. - The AS announces 14,848 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, while maintaining 12 observed routing neighbours; this ratio indicates a regional network service provider (NSP) rather than a pure transit carrier.
- Traffic from this AS consists of dedicated server solutions, colocation services, and cloud infrastructure hosted in ITsjefen's data centers in Trondheim, serving clients such as Sticos and F24 Nordics.

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.
