Summary
Granite State Communications
residential isp new-hampshire local
GSINET is the autonomous system for Granite State Communications, a locally owned provider of high-speed internet and telephone services in southern New Hampshire.
What it's used for
- The address space carries residential and small business access traffic, evidenced by reverse DNS entries such as
ip-173-209-100-0.hsi.ches.mygsc.comandhsi.weare.mygsc.com, which reference specific New Hampshire communities like Chester and Weare. - The AS announces 7,168 IPv4 addresses across 4 prefixes while maintaining only 2 observed neighbours, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
Notable
- All four announced prefixes share the registrant "Granite State Communications" and the netname
GSINET, confirming consistent ownership and management of the inventory. - The address inventory consists of four distinct IPv4 blocks, including a /20 and three /22s, with no IPv6 prefixes currently announced in the inventory.

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 2026-10-18, 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 1,784 prefixes, as published 2026-10-19. 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.
