Summary
InterStar Network Services (ShastaBeam)
isp legacy
INTERSTAR is the network of InterStar Network Services, Inc., an independent internet service provider based in Redding, California, and trading as ShastaBeam.
What it's used for
Broadband service in far Northern California. InterStar sells internet access to homes and businesses in the Shasta County area, and the addresses here are handed out to subscriber connections. It is an eyeball network, small and regional.
Notable
ARIN records the ASN from 1995, and the operator's roughly 5,000 IPv4 addresses come mostly from a single /20. The company takes transit from a couple of upstreams and has stayed independent through three decades of consolidation in US broadband.
Interesting
Rural Northern California is exactly the terrain where independent ISPs persist: too sparse and too mountainous for the national cable operators to bother with, which leaves room for a local operator willing to build where the big carriers will not.

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 2026-11-08, 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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
