About this network

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.com and hsi.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.
