About this network

Three adjacent blocks, each half the size of the last, and all three carry the same netname ending in a one.

What it's used for

• A data services company's network. Three IPv4 prefixes announced from the United States, no IPv6, three thousand five hundred and eighty-four addresses, through one observed BGP neighbour.

Notable

• The three blocks sit end to end in one parent range, and each is half the size of the one before it. They could be described in fewer announcements than they are.
• All three share a netname made of the AS handle, three letters for a block, and the numeral one. The numeral is meant to distinguish, and it distinguishes nothing, because there is no second.
• The AS handle is the company's initials with the word for a network attached, so the handle abbreviates four words down to four letters and then adds three more.
• Every block lists the company under its full legal name, comma and corporate suffix included, with no extra contact.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• Blocks that are contiguous and halving usually mean growth granted in instalments: the company came back twice, and each time the registry gave it the next piece rather than a larger one. The shape is a record of how the requests were answered.
• A single upstream carrying everything is a company that buys connectivity rather than routing. The autonomous system exists to hold the addresses, not to choose between paths.
