Summary
Cyberlink
isp enterprise legacy
Cyberlink AG is an independent Swiss managed-service provider based in Zurich, founded in 1995. The handle on this AS is CYBERLINK-TRANSIT.
What it's used for
- Business connectivity — internet access and site-to-site networking — along with managed security and cloud infrastructure, sold to Swiss companies.
- The AS itself announces a single /24 (
CYBERLINK-NET3), so this particular number carries only a slice of the company's activity rather than its whole network.
Notable
- Despite the
TRANSITin the handle, this is not a wholesale transit backbone. Cyberlink is a mid-sized provider serving on the order of a thousand-plus Swiss business customers; the label describes a role inside its own network, not its place in the internet's hierarchy. - Addresses here are corporate, not consumer. There are no residential subscriber pools in this space.
Interesting
- Cyberlink has stayed independent and Swiss-owned through three decades of consolidation in the European ISP market, which is rarer than it sounds for a provider of its size.

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.
