About this network

The holder's name ends in a number, and the number is not an address, a block or a version. It is which agency this is.

What it's used for

• A regional education agency's network. Two prefixes announced from the United States, one of them IPv6, four thousand and ninety-six addresses, through three observed BGP neighbours.

Notable

• The holder's name is a word, two initials for an intermediate unit, and a number. The number identifies the agency among its peers, which is how these bodies are named in law rather than in marketing.
• The AS handle is the agency's brand with the word for a network attached, then the initials and number repeated from the holder field.
• The netname keeps only the brand and the network word, dropping the number entirely, so the field that most needs to distinguish this agency from the others leaves out the part that does.
• The single IPv4 block is one contiguous allocation, and an IPv6 prefix is announced beside it with no matching entry in the registry inventory.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Numbered agencies are a filing system made public. Anyone inside the system knows which one this is; everyone outside sees a name that looks unfinished.
• An agency serving schools across a region routes for institutions that will never run their own networks. Four thousand addresses behind three upstreams is a small utility, and its users are buildings rather than customers.
