Summary

United States of America · AI-generated

iot m2m business

NUMEREX is operated by Numerex Corp.

What it's used for

  • The address space carries machine-to-machine connectivity, evidenced by netnames NUMEREX--SIERRA-WIRELESS and reverse DNS entries like lsp-fast-183-255.lsp01.numerex.com and h184-60-223-64.mdsnwi.dedicated.static.tds.net.
  • The AS announces 5,376 IPv4 addresses across 3 prefixes and 8 IPv6 prefixes, with only 3 observed neighbours, indicating a dedicated access network for IoT devices rather than a transit provider.
  • Traffic consists of managed M2M data for asset tracking, remote monitoring, and industrial applications, consistent with Numerex's business of providing end-to-end connectivity services for connected devices.

Notable

  • Registrants for all announced prefixes are listed as Numerex Corp or NUMEREX CORP, aligning with the AS holder.
  • Numerex Corp was acquired by Sierra Wireless in a $107 million deal, explaining the SIERRA-WIRELESS reference in the netname for the 199.91.164.0/22 block.
  • The inventory includes a mix of legacy TDS.net static blocks and dedicated Numerex infrastructure, reflecting the company's history in wireless connectivity.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
