KANTONAR is operated by Kanton Appenzell Ausserrhoden.
What it's used for
- The space carries the cantonal government's internal network, identified by the netname
KTARand registrantKanton Appenzell Ausserrhoden. - The AS announces 512 IPv4 addresses in a single /23 prefix and 1 IPv6 prefix, while maintaining 43 observed neighbours; this ratio of limited address space against a high neighbour count indicates a transit or peering-heavy role for the canton's infrastructure.
- Traffic from this AS consists of government administrative services, public sector communications, and internal backhaul for the canton of Appenzell Ausserrhoden.
Notable
- The RDAP registrant
Kanton Appenzell Ausserrhodenmatches the registry holder and the AS handleKANTONAR, confirming direct ownership by the cantonal government. - The address inventory is compact, consisting of one IPv4 block and one IPv6 block, typical for a small Swiss canton's dedicated government network.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
