Summary

Addsec AB

Sweden · AI-generated

security business it-services

The AS handle ADDSEC is held by Addsec AB.

What it's used for

  • The space carries corporate infrastructure for an IT security firm, evidenced by reverse DNS entries addsec.se and ip127.securesolution.net.
  • The network announces 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and web/API endpoints for a company providing secure IT consulting, installation, and maintenance services.

Notable

  • The registrant Addsec AB matches the AS holder, with the netname SE-ADDSEC-20240110 confirming ownership.
  • The address inventory is a single /24 block, consistent with a small corporate estate.

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: 446 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.
