About this network

A German provider whose netnames number themselves by the third octet of each block.

What it's used for

• Business connectivity and hosting. 3,328 addresses in seven IPv4 prefixes, one IPv6 /32, and three observed BGP neighbours.

Notable

• The netnames are BICOS-NET-32, BICOS-NET-36, BICOS-Net-96 and BICOS-Net-98. Each number is the third octet of the block it labels.
• The capitalisation splits by range: the 212.100 blocks use NET, the 185.3 blocks use Net.
• Two pairs share a netname. 212.100.32.0/23 and 212.100.34.0/23 are both BICOS-NET-32, and 185.3.98.0/24 and 185.3.99.0/24 are both BICOS-Net-98.
• Every record is registered to BICOS NCC.

Interesting

• Naming a block after its own third octet works until you subdivide, and then two networks answer to one label. That is exactly what happened here twice, which is the failure mode of every scheme that encodes an address into a name: the address stops being unique before the name does.
• The case change is a smaller tell. 212.100 space was requested in one era and 185.3 in another, and between them somebody's habits changed, or somebody else started filling in the forms.
