About this network

The counter in the netname is spelled out as a word rather than written as a digit.

What it's used for

• A broadcaster's network. Four IPv4 prefixes announced from the United States, no IPv6, nine thousand four hundred and seventy-two addresses, through two observed BGP neighbours.

Notable

• The AS handle is three initials, one for each word of the holder's name.
• All four blocks are registered to the holder, and all four carry the same netname: those initials, the word for a network, and the number one written out in letters.
• The four blocks are pieces of a single parent range at three sizes, scattered rather than contiguous.
• Twelve addresses were queried for reverse DNS and none returned a name.
• Two observed neighbours carry the whole announcement.

Interesting

• A counter spelled as a word is unusual. Digits sort, group and increment; a word does none of those things, which means this label was written for a person to read rather than for a system to process.
• One netname across four blocks says the registry can group them and can tell you nothing about which is which. The distinctions live in a system that never reaches the registry.
• Nine thousand addresses through two upstreams, with nothing answering a reverse lookup, describes a network that distributes to member stations rather than one that serves the public directly. What the public sees lives somewhere else entirely.
