About this network

IMPU is the network of Impulse Internet Services, registered to Aseva LLC and operating out of Goleta, California, next door to Santa Barbara.

What it's used for

Impulse is an independent regional ISP. It sells broadband and business connectivity on California's central coast, and the addresses here are handed out to subscriber circuits. It is an eyeball network first, with a modest amount of hosting and business-services address space alongside.

Notable

Nearly 60,000 IPv4 addresses sit behind this AS, anchored on a legacy /18 that has been in the operator's hands since the mid-1990s. That is a large footprint for a regional independent, and a useful reminder that address holdings scale with when you showed up as much as with how big you are.

Interesting

Impulse is one of the small cohort of 1990s-vintage local ISPs that never got swallowed by a cable company. It still runs its own AS, its own peering, and dual-stack IPv6, which is more than can be said for plenty of far larger networks.
