AS27501 — ISPNET-AS
AS27501 announces 16 IPv4 prefixes covering 37,120 addresses and 0 IPv6 prefixes.
About this network
The AS handle ISPNET-AS is held by isp.net.
What it's used for
- The address space carries residential and local access traffic, evidenced by reverse DNS pointers to isp.net, lv.net, and lasvegas.net (e.g., ip-64-250-247-254.isp.net).
- With 37120 IPv4 addresses announced across 16 prefixes and only 7 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants are consistent with the announcer, appearing as isp.net or ISP.NET LLC across all sampled prefixes.
- The inventory is a mix of large /19 blocks and smaller /22 to /24 allocations, with netnames like LASVEGASNETWORK2 and LVNETBLOCK3 suggesting a regional focus in Las Vegas.
