About this network

A German IT services provider's network, carrying the name of the ISP it grew out of.

What it's used for

• Business connectivity and managed hosting. 42,496 addresses in five IPv4 prefixes, one IPv6 /29, 118 observed BGP neighbours.

Notable

• Three netnames carry both companies at once: DE-SCANPLUS-QBY-19990908, DE-SCANPLUS-QBY-19990617 and DE-SCANPLUS-QBY-20180227. The acquired name, the acquirer's initials and the date, in one string.
• The other two prefixes belong to customers. 193.24.12.0/24 is BERKA-LAN, registered to the timber company Pfeifer Holz; 213.153.66.0/24 is HS-Net-NLs, whose contacts are CIRCULAR NETMASTER and CIRCULAR GUARDIAN.
• That last block's addresses answer positionally as host64-66.circular.de — the customer's own domain over the provider's numbering scheme.

Interesting

• The two 1999 allocations are three months apart, a /19 in June and a /17 in September. Getting 32,768 addresses on a second request inside one year says the first estimate was wrong in the direction that was easy to fix at the time.
• An IPv6 /29 is a very large allocation — the standard is a /32, and a /29 is eight of them. It was handed out to European members who asked, in an address family where asking for more was never the constraint.
