About this network

The AS handle carries a street address and a house number.

What it's used for

• A regional utility company's network. A single IPv4 /24 announced from Germany, no IPv6, two hundred and fifty-six addresses, through two observed BGP neighbours.

Notable

• The AS handle is the company code followed by a street name and a number, which is postal information in a field meant for a network identifier.
• The one block lists three registrants: the company, an abuse role, and a role account belonging to a differently named organisation.
• The netname is the company name and the country code, with nothing else.
• Three addresses were queried for reverse DNS and none returned a name.
• Two hundred and fifty-six addresses, announced whole, unchanged in shape since the network first appeared.

Interesting

• A street address in an AS handle is a copy-and-paste artefact from a paper form, preserved because nothing in the system objects to it and nobody has needed to change it since.
• The third registrant, a role account under another name, is the tell that the network is run by somebody else. Utilities buy their connectivity and their operations, and the record shows who.
• The smallest routable block with two upstreams is what a company buys when it needs to stay reachable rather than to serve traffic. Reliability, not capacity.
