Summary

Localhost AS

Norway · AI-generated

business norway small

LOCALHOST_AS is held by Localhost AS.

What it's used for

  • The space carries a single IPv4 block with netname NO-LOCAL-HOST-20120726 and registrant LOCALHOST AS; Teknisk avdeling.
  • 2048 IPv4 addresses and 1 IPv6 prefix are announced against 3 observed neighbours, indicating a small-scale access or internal network rather than a transit provider.
  • The registrant identifies the technical department (Teknisk avdeling), suggesting the space supports internal corporate infrastructure or specific service endpoints.

Notable

  • The registrant LOCALHOST AS matches the AS holder name exactly.
  • The address inventory consists of one contiguous /21 IPv4 block and a single /29 IPv6 prefix, representing a compact and uniform allocation.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
