Summary
AZISTA
isp residential austria access
The AS handle ASN-AZISTA is held by AZISTA GmbH.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
network.findmyhome.atandbroadcast.cix.at. - The network announces 8960 IPv4 addresses across 6 prefixes, with a neighbour count of 5, indicating a role as an access or eyeball network rather than a transit provider.
Notable
- Registrants for five of the six prefixes are listed as "AZISTA Hostmaster; AZISTA GmbH", consistent with the announcer.
- The prefix 195.62.26.0/23 is registered to "Sascha Pollak KG" under the netname
CYBERATELIER, which differs from the primary AZISTA registrant. - The inventory consists of six IPv4 prefixes with no IPv6 prefixes announced.

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 1,773 prefixes, as published 2026-10-13. 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.
