Summary
Onward
residential isp cable dsl
INYO is the AS handle for Onward, a regional cable and DSL internet service provider.
What it's used for
- The address space carries residential broadband traffic, evidenced by registrant netnames such as
IN-85andITCM-70-98-52-0-23associated with Inyo Networks. - The AS announces 8704 IPv4 addresses across 16 prefixes and 1 IPv6 prefix, while maintaining only 6 observed routing neighbours; this high address-to-neighbour ratio indicates an access network rather than a transit provider.
Notable
- Registrants for the majority of prefixes are listed as Inyo Networks, which aligns with the AS holder, though one prefix (
23.130.128.0/23) is registered to the American Registry for Internet Numbers. - The operator is also known as Onward, reflecting a rebranding or alternate identity for the Inyo Networks entity.
- The inventory consists of a mix of /21, /22, /23, and /24 blocks, with the largest being
209.40.72.0/21.

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 2026-10-19, 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 1,778 prefixes, as published 2026-10-20. 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.
