Summary

LANAIR Group

United States of America · AI-generated

business it consulting us

The AS handle LANAIR-LGCLOUD is held by LANAIR Group, LLC.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by the netname CALIFORNIA-NET1 and reverse DNS entries pointing to californiatelecom.com.
  • The inventory consists of 256 IPv4 addresses within a single /24 prefix, with 1 observed neighbour, indicating a small-scale internal or business network rather than a transit provider.

Notable

  • The registrant California Telecom differs from the AS holder LANAIR Group, LLC, suggesting the address space may be leased or historically associated with a different entity.
  • The address inventory is compact, consisting of a single contiguous /24 block with no announced IPv6 prefixes.

Reputation

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
