About this network

The reverse zone names the town each address serves, and labels the spare ones avail.

What it's used for

• A regional education agency's network. 2,304 addresses across five IPv4 prefixes plus 2620:8b:c000::/48 of IPv6, with four observed BGP neighbours.

Notable

• Twelve of fifteen sampled addresses answered, all under txed.net.
• Five town labels appear in those names, including wimberley, lockhart and libertyhill.
• Six of the twelve answers use the label avail in place of a town.
• The netnames are ESC13-1, ESC13-3 on three blocks, and TXESCREG13.

Interesting

• A zone that marks unassigned addresses avail turns reverse DNS into a live inventory. Anyone can query it and learn which addresses the agency has spare, how many each district holds, and where the free space is concentrated. That is a genuinely useful working tool and an accidental disclosure at the same time.
• The names come in two formats: some carry one part of the address, some carry two, and network addresses get the label net instead of digits. The two formats mark two generations of the script that builds the zone.
• Numbers are padded to three digits, so 064 sorts next to 127. Somebody wanted the zone file to read in order.
• Distributing address space by town is how a shared regional network keeps districts separable without giving each its own routing.
