AS14296 announces 1 IPv4 prefixes covering 256 addresses and 1 IPv6 prefixes.

About this network

A fire department with its own autonomous system number and an IPv6 block to go with it.

What it's used for

• An emergency services network. 256 addresses in a single IPv4 prefix alongside an IPv6 2602:80e:8000::/44, with one observed BGP neighbour.

Notable

• The IPv4 block is 104.36.227.0/24, carrying the netname SPRINGFD-V4-1 and registered to the department.
• That netname marks the address family explicitly, which implies a matching record for the other one.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Running an autonomous system is not what a fire department normally does. It means dispatch and radio systems that have to keep working when one provider fails, and the number is what makes changing providers possible without renumbering anything.
• The IPv6 allocation is far larger than anything the IPv4 side suggests, which is the standard shape for a recent request and gives room for per-station and per-vehicle addressing.
• Marking the address family in the netname is a small discipline that pays off later: the two families end up in different registries at different times, and matching labels are how they get found together.
• One observed neighbour beside two address families is the part worth watching for a network whose purpose is availability.
