About this network

An Austrian cable television company turned provider, with one PTR for the entire network.

What it's used for

• Cable internet access. 3,072 addresses in two IPv4 prefixes with four observed BGP neighbours and no IPv6 announced.

Notable

• Every address sampled, across both blocks and both allocations, answers with the same name: customer.kabeline.at. Six queries, six identical PTRs.
• The AS handle carries a comment: KABELINE-AS # IP-Transit JM-DATA AS25447, naming the transit provider and its AS number.
• The registered holder is Ernst Klingler Kabelfernsehen Gmbh, and the netnames are AT-KABELINE-20100105 and AT-KABELINE-20151222.

Interesting

• A single flat PTR for every address is a real choice, and an unusual one. Most providers generate a name per address so that logs and traceroutes identify the line; this one answers the question with a category instead. Everything behind it is a customer, and that is all the reverse tree will say.
• The comment in the handle is a note left for other network operators in the only field available. Whoever wrote it wanted anyone looking up this AS to know immediately who to call upstream, so they put it where the name goes.
