AS5619 NO-TTSN-ASN1 TietoEVRY Norway
Unclassified RIPE
Summary
Tietoevry Norway
hosting enterprise legacy
NO-TTSN-ASN1 is the Norwegian network of Tietoevry, the Nordic IT services group (the RIPE org record still reads Tieto Norway AS, in Oslo). Tietoevry runs managed IT, outsourcing and hosting for Norwegian enterprises and public-sector bodies, and this AS carries that infrastructure.
What it's used for
Managed hosting and outsourced IT. Address space here fronts customer systems operated inside Tietoevry's facilities and the company's own corporate network — servers and business services, not consumer access. The AS is present at NIX1 and NIX2 in Oslo.
Notable
The inventory is unusually large for an IT services firm — over a million IPv4 addresses — because it is dominated by pre-CIDR legacy blocks such as 139.106.0.0/15, 139.108.0.0/14, 153.110.0.0/16 and 146.213.0.0/16. Address count is a poor proxy for active hosts on a network shaped like this; large tracts of that space are historical rather than densely populated.
Interesting
The handle preserves a name the company no longer uses, and the RIPE object still routes abuse and peering mail through @evry.com addresses. Tieto, EVRY and their predecessors merged over decades of Nordic IT consolidation, and the registry kept every layer.

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.
