Summary
Salzburg AG (CableLink)
isp residential eyeball cable legacy
Salzburg AG für Energie, Verkehr und Telekommunikation (SALZBURG-AG-AS) — the utility company of the Austrian state of Salzburg, which alongside electricity, gas, water and public transport runs the CableLink broadband network.
What it's used for
- Consumer and business internet across the Salzburg region. The address space is overwhelmingly CableLink subscribers: dynamic pools named
IP-ADDR-IP-ADDR.dyn.cablelink.atand static assignments namedIP-ADDR-IP-ADDR.stat.cablelink.at. - Corporate and infrastructure hosts sit under
salzburg-ag.at(ns1.salzburg-ag.at,mx00.salzburg-ag.at).
Notable
- An eyeball network of roughly 240,000 IPv4 addresses — large for a regional utility, and heavily peered.
- Geolocation should be regional. This is Salzburg city and state, not Austria at large.
Interesting
- Municipal and regional utilities becoming ISPs is a common Austrian and German pattern: the company already owns the ducts, the rights of way and the billing relationship with every household, so laying coax or fibre alongside the power network is a natural extension.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
