Unclassified ARIN
Summary
Siskiyou Telephone Company
telecom rural access california
NET-SISQTEL-NET1 is operated by Siskiyou Telephone Company.
What it's used for
- The address space carries rural telecommunications services, evidenced by reverse DNS entries pointing to
sisqtel.netand netnames registered asSISKIYOU. - With 4608 IPv4 addresses announced across 2 prefixes and only 4 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network serving local subscribers rather than a transit provider.
Notable
- Registrants for both announced prefixes (
137.119.64.0/20and137.119.26.0/23) are consistently listed as SISKIYOU TELEPHONE COMPANY, matching the AS holder. - The address inventory is compact, consisting of a single /20 and a single /23 block, typical of a small regional carrier managing its own local loop infrastructure.

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.
