About this network

Reverse names are the address as twelve digits with no separators, and two still say dial-up.

What it's used for

• A community college network. Five IPv4 prefixes and one IPv6 /48 announced from the United States, through one observed BGP neighbour.

Notable

• Most answering addresses are named with a single letter followed by the whole address, every octet padded to three digits and run together, giving twelve digits in one unbroken label.
• Two others are named for a serial line dial-up protocol with a port number, a technology retired decades ago and still described in the college's zone.
• Two of the five blocks are registered to a state university system under netnames naming a shared education network.
• The college's own blocks use three different netname formats, one with a counter, one hyphenated, one with an abbreviation for network block.
• Fifteen addresses were queried for reverse DNS and eight returned a name.

Interesting

• Twelve unbroken digits is machine friendly and human hostile. It parses only if you know the padding rule, and it is the least readable address encoding in this range.
• The dial-up names date the zone better than any registry field. Somebody generated them for a modem pool, the pool went away, and the records outlived it.
• Blocks held by a state system inside a college's routing is how public education networks are usually built: the system holds the address space, the institution announces its own share.
