Summary
Quickline
cable residential isp switzerland
FLASHCABLE is the AS handle for Quickline AG, a Swiss cable television and internet service provider.
What it's used for
- The address space carries residential cable broadband traffic, evidenced by reverse DNS entries such as
dyn.cable.qlnet.chanddhclient-*.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
- Registrants for the largest prefixes are Quickline AG, while smaller blocks are registered to GIB-Solutions AG and Tele alpin AG, reflecting historical acquisitions or leased space within the Flashcable network.
- 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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,771 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
