AS10858 HYPER-BNG-ASN - Hypertherm Inc.
Unclassified ARIN
Summary
Hypertherm Inc.
enterprise legacy
HYPER-BNG-ASN belongs to Hypertherm, the employee-owned industrial manufacturer based in Hanover, New Hampshire that makes plasma, laser and waterjet cutting systems. This is a corporate network, not a provider.
What it's used for
A small multihomed enterprise edge. RIS sees just 2 announced IPv4 prefixes — 72.236.28.0/24 and 136.143.136.0/24, 512 addresses in total — no IPv6, and 2 observed BGP neighbours.
Two /24s behind two upstreams is the minimum viable shape for an organisation that wants provider-independent addressing and carrier redundancy without being a network operator in any other sense. The company runs its own ASN so that its published services keep the same addresses when it changes ISPs, and so that a single carrier outage does not take those services offline. Everything else — staff, factory floor, engineering — sits behind NAT on private space and never appears in the routing table.
The one sampled PTR resolves to xnet.hypertherm.com, a first-party hostname on the company's own domain, which is consistent with the routed space carrying Hypertherm's internet-facing systems and nothing else.
Notable
Read the handle carefully rather than by resemblance. BNG here is part of the organisation's registered ARIN handle, not the networking term "broadband network gateway"; nothing in the routing suggests this AS aggregates subscriber sessions, and nothing in it suggests a service business.

Interconnection
Peering at a glance
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 2026-11-11, 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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
