About this network

One netname is a sentence describing the equipment: access protocol, access server and address sharing.

What it's used for

• A city network operator. Fifteen IPv4 prefixes and two IPv6 prefixes announced from Germany, sixteen thousand six hundred and forty addresses, across one hundred and thirteen observed BGP neighbours.

Notable

• One block's netname is a phrase joined by hyphens: the dial-up-style access protocol, the word for a broadband access server, and a contraction for the system that shares one address between many subscribers. It describes the equipment rather than the customers.
• Four blocks carry a date of the first day of a year long before the registry existed, which is the placeholder used when the real date is unknown.
• The other netnames use the same country code and brand with real dates spread across three decades.
• The AS handle is the brand followed by a street name and a house number, with no city or country.
• One hundred and thirteen neighbours on sixteen thousand addresses is a very high ratio, the shape of a network that peers widely rather than buying transit.
• Two of eighteen queried addresses answered, the four octets hyphenated on a subdomain for the provider business.

Interesting

• Naming a block after address sharing is useful information leaking out of a form. It tells anyone reading that many subscribers sit behind each address, which matters for anyone trying to block, rate limit or geolocate one of them.
