About this network

Fast Enterprises writes the tax administration and motor vehicle software that US state agencies run on.

What it's used for

• Corporate and service delivery networking. 2,560 addresses across six prefixes, two observed BGP neighbours, no IPv6 announced.

Notable

• All six prefixes carry one netname, FEL16, with no subdivision by site or function.
• They also come out of one contiguous stretch: a /22, a /23 and four /24s, all between 170.10.96.0 and 170.10.108.0.
• Two neighbours against 2,560 addresses. The network exists to serve the company, not to carry anyone else's traffic.

Interesting

• Revenue systems are among the longest-lived software in government. A state replaces its tax administration platform roughly once a generation, in a multi-year project touching every tax the state collects, which is why a private company most people have never heard of ends up as a quiet dependency of state finance across much of the country.
• An address plan that stayed this simple says something about the business. Six prefixes and a single label means the company never had to hand address space to a division, a subsidiary or an acquisition, and the registry entry is one of the few public records that shows it.
