Summary
Huntleigh Technology Group
business isp managed-services msp
HTG is Huntleigh Telcom, now trading as the Huntleigh Technology Group — a New Jersey firm that started as a telecom/Internet provider and has grown into a managed IT services business, selling connectivity alongside network support, backup, voice and security services to companies.
What it's used for
- Business Internet access and hosted services for HTG's customers, delivered out of the company's own routed address space rather than resold provider pools.
- The company's own infrastructure —
209.136.36.5resolves towww.htg.net, so its public web presence lives inside the same space it hands to customers.
Notable
- A small business-focused provider, not an eyeball ISP and not a carrier. RIS sees 19 IPv4 prefixes carrying only about 4,096 addresses, with 2 observed BGP neighbours. Two neighbours rules out transit outright. The very small address pool rules out a consumer broadband base of any size.
- Reverse DNS is the clincher and needs reading carefully. Nearly every sampled address resolves to
cust-<block>.<host>.htg.net— a customer label, applied by HTG, on HTG's own domain. That tells you the space is assigned out to end customers, but the volume tells you those customers are businesses taking a handful of statics each, not households on a subscriber pool. - All 19 prefixes come from two blocks,
209.136.26.0–209.136.36.0and216.253.7.0–216.253.11.0, announced as both aggregates and constituent /24s. A high prefix count against 4,096 addresses is traffic engineering, not scale.
Interesting
- One sampled PTR breaks the
cust-pattern (edm-27.133.htg.net), a reminder that operator infrastructure and customer assignments share the same blocks.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
