AS7733 FRZRMTN

Autonomous System 7733 (FRZRMTN) belongs to **Frazier Mountain Internet

Service**, a small independent fixed-wireless ISP based in Pine Mountain Club,

California, serving the mountain communities of the Frazier Mountain area.

What it's used for

• Carrying broadband access for homes and small businesses in the communities around Frazier Mountain — Pine Mountain Club, Frazier Park, Lebec, Lake of the Woods, Cuddy Valley and Lockwood — over a wireless (line-of-sight) plant built for mountainous terrain that wired carriers largely skipped.
• Originating just two adjacent /24s of legacy ARIN space, plus the routers, towers and mail/web servers needed to run them.

Notable

• This is a genuine eyeball network, but an unusually small one: about 512 IPv4 addresses in total. Addresses here belong to real subscribers in a rural Southern California mountain area, not to a datacentre.
• The tiny address footprint is normal for a rural wireless ISP — subscribers are typically numbered behind carrier-grade NAT, so the public pool stays small regardless of how many households are connected.

Interesting

• The operator has been serving these communities since the mid-1990s, which is consistent with the era of its ASN and its two legacy /24s. Small community-scale ISPs of this vintage have overwhelmingly been bought up or shut down; a handful, like this one, still hold and announce their own space.
