Summary

Thomas & Betts Corporation

United States of America · AI-generated

business corporate internal

TNB-NET is the autonomous system for Thomas & Betts Corporation.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS entries like tnbs128.tnb.com and tnbd64.tnb.com which map to the company's tnb.com domain.
  • With 1792 IPv4 addresses across 5 prefixes and only 3 observed neighbours, the ratio indicates a small, self-contained internal network rather than a transit or access provider.

Notable

  • All registrants in the RDAP data consistently identify as Thomas & Betts Corporation, with some prefixes also listing Global Technologies -Network Services.
  • The address inventory is finely subdivided into five distinct blocks, including two /23s and three /24s, reflecting site-by-site segmentation typical of a large corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, 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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
