AS15600 QUICKLINE Quickline AG
Residential RIPE Cable/DSL/ISP
Summary
Quickline
isp telecom media infrastructure
Reverse names say whether the subscriber is on cable or on fibre.
What it's used for
- A broadband provider. Fifty-five IPv4 prefixes and twenty-two IPv6 prefixes announced from Switzerland, three hundred and nineteen thousand addresses, across fifty-five observed BGP neighbours.
Notable
- Every answering address is named with all four octets in reverse order, then a marker for a changing address, then the access medium, then the company domain. Some names say cable and some say fibre.
- Ten of the IPv6 prefixes are
/29blocks, each the size a registry allocates to a whole member organisation, held by one network. - One netname carries an allocation date more than a decade older than the next oldest here.
- Blocks name six other companies as co-registrants, several of them cable operators, one written entirely in lowercase and one with a capital letter in the middle of the brand.
- Two large blocks are listed by the registry as managed with no registrant at all.
- Eighteen addresses were queried for reverse DNS and eleven returned a name.
Interesting
- Publishing the access medium in the hostname tells anyone measuring the network which customers sit on old coaxial plant and which have been moved to glass, without asking the operator anything.
- Ten member-sized IPv6 allocations is the clearest possible record of a company assembled from other companies. Each acquisition brought its own, and none was ever given back.
- Three hundred thousand addresses on fifty-five neighbours is a residential network: many customers, modest interconnection, and a naming scheme built for support staff.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
