Unclassified ARIN
Summary
Isotropic Networks
business connectivity satellite wireless
The AS handle ISOTRASN is held by Isotropic Networks, Inc.
What it's used for
- The address space carries converged connectivity services, with netnames such as
ISOTROPIC-NETWORKSandISOTROPICindicating corporate infrastructure for terrestrial wireless and satellite solutions. - The AS announces 18,688 IPv4 addresses across 10 prefixes, while maintaining only 2 observed neighbours, a ratio that suggests a specialized access or enterprise network rather than a transit provider.
Notable
- Registrants consistently identify as IsoTropic Networks, Inc. or Isotropic Networks, aligning with the AS holder despite some legacy SBC-era netnames like
SBCIS-080106115130. - The address inventory consists of a mix of /21, /22, and /24 blocks, including a /20, reflecting a segmented corporate estate rather than a large residential footprint.

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.
