What it's used for

• The address space carries residential cable broadband traffic, evidenced by reverse DNS entries such as dyn.cable.qlnet.ch and dhclient-.flashcable.ch.
• The AS announces 39,168 IPv4 addresses across 17 prefixes and 2 IPv6 prefixes, while maintaining only 5 observed neighbours, a ratio characteristic of an access network rather than a transit provider.
• Traffic from this AS consists of subscriber eyeballs accessing the internet via Quickline's cable infrastructure.

Notable

• The inventory includes prefixes registered to Helvetische Bank AG, indicating a diverse set of historical allocations now aggregated under the Quickline AS.
• The address inventory is fragmented across multiple /19, /20, and smaller blocks, consistent with a network grown through successive acquisitions of regional cable operators.
