AS15577 announces 1 IPv4 prefixes covering 256 addresses and 1 IPv6 prefixes.

About this network

Three different three-letter abbreviations appear across the holder, the handle and the registrant.

What it's used for

• A small provider. One IPv4 /24 and one IPv6 /48 announced from Ukraine, two hundred and fifty-six addresses, across five observed BGP neighbours.

Notable

• The holder name, the AS handle and the block's registrant each use a different abbreviation, none of which is derived from either of the others.
• The netname follows the handle's abbreviation while the registrant follows a third one, so the two fields on the same block disagree.
• The single answering address names a business and a city under the registrant's abbreviation as a domain.
• The one block lists an abuse team as its only registrant, with no company named.
• Three addresses were queried for reverse DNS and one returned a name.

Interesting

• A single hostname is enough to place a network. This one gives a city and the name of a company that sits inside the range, from a sample of three addresses.
• Five neighbours behind two hundred and fifty-six addresses is a lot of redundancy for very little space, and it is what a small provider buys instead of more addresses.
• Three abbreviations for one organisation is how renaming looks when each record is updated on its own schedule and none of them finishes.
