AS21515 announces 2 IPv4 prefixes covering 4,608 addresses and 1 IPv6 prefixes.
About this network
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.net and netnames registered as SISKIYOU.
- 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 (137.119.64.0/20 and 137.119.26.0/23) 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.
