About this network

Every field in the record is the same single word, and the handle spells out what an AS is in lower case.

What it's used for

• A provider. A single IPv4 prefix announced from Ukraine, no IPv6, five hundred and twelve addresses, through two observed BGP neighbours.

Notable

• The AS handle is the brand in capitals, then the brand again in ordinary case, then the words autonomous system spelled out in lower case, describing the object rather than naming it.
• The netname is the brand alone. The holder field is the brand plus a legal form. Three fields, one word.
• The whole holding is a single block of two smallest-routable ranges joined together, which is an unusual size to hold and nothing else.
• The block is registered to the company and a role for abuse, with no operations contact and no maintainer named.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Spelling out autonomous system inside an autonomous system's own handle is the same instinct that writes the word bank on the outside of a bank. The field was free text for years, and some operators filled it in for a human reader who was never going to arrive.
• Five hundred addresses and two upstreams is a provider serving a specific set of customers rather than a market. The second connection is the entire redundancy plan.
