Summary

CoreIT AB

Sweden · AI-generated

business enterprise sweden

The AS handle KARNIT is held by CoreIT AB.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname SE-KARNIT-20180816 associated with the registrant CoreIT AB.
  • The inventory consists of 17,408 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 2 observed routing neighbours.
  • This low neighbour count relative to the address block size indicates an internal corporate estate rather than a transit or access provider, consistent with CoreIT AB's role as an IT services company managing its own network resources.

Notable

  • The registrants align with the announcer, with CoreIT AB listed for the primary prefix and Ovik Energi AB for the secondary prefix 85.11.192.0/18.
  • The address inventory is split between two distinct blocks: 85.11.192.0/18 registered to Ovik Energi AB and 81.21.224.0/22 registered to CoreIT AB, suggesting a multi-entity or acquired asset structure within the same autonomous system.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
