AS15836 AXAUTSYS ARAX AS

Four answering addresses, three naming conventions, two domains.

What it's used for

• A provider's network. Twenty-one IPv4 prefixes and one IPv6 /32 announced from Moldova, twenty-seven thousand six hundred and forty-eight addresses, across thirty-eight observed BGP neighbours.

Notable

• One answering name is a single letter and the last octet. Another is a three-letter contraction of the brand, the third octet, a hyphen and the fourth. Two more are the word for a host with all four octets hyphenated.
• The second of those sits on a second domain, built from the brand and the word for information, while the others use the brand under the country's own suffix.
• Most netnames are a country code, the brand with a commercial suffix attached, and one of seven allocation dates spread over fourteen years.
• One netname instead names the dial-up-era access protocol still used over broadband, followed by three octets of the block it sits on.
• The registered holder's name ends in a word meaning import and export, which is what the company was set up to do before it sold connectivity.
• Of eighteen addresses queried, four returned a name.

Interesting

• Three conventions in a four-address sample means the zone has been rewritten at least twice and the old entries were never cleared. Each one was somebody's improvement on the last.
• Naming a block after the access protocol tells anyone reading that these addresses are handed to subscriber sessions rather than to servers.
