isp residential business us

HX-ISP-CHO is operated by Helix Computer Systems, Inc.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries like this-is-broken-call-tony-434-817-7812.helixsystems.com and netnames such as HXPC-ISP-CHO and ACC-HELIX-213.
  • With 3584 IPv4 addresses announced across 3 prefixes and only 2 observed neighbours, the ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, with Helix Computer Systems, Inc. holding the largest blocks, though Xenir, LLC is listed for the 208.93.96.0/22 prefix.
  • The inventory consists of three distinct IPv4 prefixes with no IPv6 announcements, reflecting a legacy IPv4-only footprint.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
