About this network

IMPNET-AS is ImproWare AG, a Swiss internet service provider based in Pratteln, near Basel, which sells broadband under the breitband.ch brand.

What it's used for

• Residential and business broadband. The largest announced block is registered with the netname BREITBAND-NET and its registry remarks state plainly that it holds "DOCSIS or FTTH DHCP pools", so this is cable and fibre subscriber addressing.
• Reverse DNS matches: subscriber addresses resolve in a cable-static-<address>.breitband.ch form.

Notable

• The network carries a legacy 157.161.0.0/16, a full Class B. That is an unusually large holding for a regional provider and makes up most of its roughly 115,000 announced IPv4 addresses.
• ImproWare does not own the cable plant. It sells internet over the networks of local cable operators across dozens of municipalities in northwest Switzerland, starting from a partnership with the Pratteln cable co-operative, while running its own ASN, IPv6 (2001:4060::/32) and network services rather than reselling another carrier's access wholesale.
