Summary
Innsbrucker Kommunalbetriebe AG
cable dsl isp municipal
The AS handle IKB-AS is held by Innsbrucker Kommunalbetriebe AG, a municipal utility company in Innsbruck.
What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS entries like
clnet-p25-255.ikbnet.co.atand netnames such asIKB-AG-Fiber-AT-NET-087. - The AS announces 27,904 IPv4 addresses across 11 prefixes and 1 IPv6 prefix, while peering with 933 neighbours; this high neighbour count relative to the address block size indicates a regional access provider rather than a transit carrier.
Notable
- Registrants for the majority of prefixes are consistent with the announcer, listing "NOC IKBNET Team; Innsbrucker Kommunalbetriebe AG", though one prefix (
193.228.93.0/24) is registered to "infowerk Medien & Technik GmbH". - The address inventory is finely subdivided into multiple /22, /23, and /24 blocks within the 83.175.0.0/16 range, reflecting site-by-site segmentation of the corporate and customer estate.

Reputation
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.
