About this network

A registered association running its own number and one block, with a domain name for a company name.

What it's used for

• A member association's network. One IPv4 /24 announced from Germany, no IPv6, two hundred and fifty-six addresses, through a single observed BGP neighbour.

Notable

• The holder is a registered association rather than a company, so the network belongs to its members.
• The company name is a region followed by a dot and the abbreviation for a network, which is a domain name used as a legal name.
• The AS handle is that region name with a trailing hyphen and nothing after it, so a suffix was intended and never typed.
• The netname is the same region with the three letters for a network, this time hyphenated in the ordinary way.
• The block lists the association and a contact for abuse, with no role code between them.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Associations appear in the routing table wherever commercial providers found a region unprofitable. Neighbours pool money, buy transit once, and the legal form that fits is the one used by sports clubs.
• Running an AS number for two hundred and fifty-six addresses is more paperwork than a small network needs, until the alternative is renumbering every time the association changes providers.
