About this network

Two spellings of the same generated hostname, differing by one hyphen, inside a single block.

What it's used for

• A German regional internet provider. 175,872 addresses across 11 IPv4 prefixes, seven IPv6 prefixes, and 121 observed BGP neighbours.

Notable

• Seven of 18 sampled addresses returned names, in two forms that differ by a single character: a-89-182-128-0.net-htp.de and a89-182-255-255.net-htp.de.
• Both forms appear inside the same 89.182.0.0/15.
• Own netnames run DE-HTN-990315, DE-HTN-20020801, DE-HTN-20060406 and DE-HTN-20150325.
• Three blocks belong to other organisations, including one to the city of Hannover, netname LHHTEKI-LAN.

Interesting

• One hyphen separating the leading letter from the address in some names and not others is a generator that was rewritten and never applied backwards over the space it had already filled. The two forms resolve equally well, so nothing forces the fix, and the boundary between them marks where the change happened.
• A city government's local network sitting under a regional provider's AS number is the municipal utility model: the same company that runs the town's other services also runs its connectivity, and the registry keeps the two holders separate.
• 990315 and 20150325 again show the six-digit and eight-digit date forms in one holder's records, sixteen years apart.
