Summary

Layer 3 Communications

United States of America · AI-generated

business enterprise us

LAYER-3-COMMUNICATIONS is operated by Layer 3 Communications.

What it's used for

  • The address space is registered under the netname LCGL-2 for all five announced IPv4 prefixes, indicating a single corporate estate.
  • The AS announces 2560 IPv4 addresses across 5 prefixes and 13 IPv6 prefixes, with only 3 observed neighbours, a ratio consistent with an internal corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and data flows for Layer 3 Communications, a US-based telecommunications and data services provider.

Notable

  • All registrants for the announced prefixes are Layer 3 Communications, matching the AS holder.
  • The inventory is finely subdivided into small /22, /23, and /24 blocks, typical of site-by-site segmentation within a large enterprise.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
