Summary

Perfect Sense AB

Sweden · AI-generated

business swedish small

PERFECTSEN is operated by Perfect Sense AB.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames SE-PERFECTSENSE-20230503 and SE-PERFECTSENSE-19951012 registered to Perfect Sense AB.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for Perfect Sense AB, a Swedish company based in Gothenburg.

Notable

  • Registrants for both announced IPv4 prefixes align with the AS holder, listing Perfect Sense AB as the registrant.
  • The address inventory is compact, consisting of two /24 IPv4 blocks and two /48 IPv6 blocks, consistent with a single corporate entity managing its own IP space.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, 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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
