Summary
Kanton Zug
government canton switzerland
The AS handle CH-ZG is operated by Kanton Zug, the cantonal government of Zug in Switzerland.
What it's used for
- The address space carries government infrastructure, with both IPv4 prefixes registered under the netname
CHKTZG01and registrants listed as "Kanton Zug - Amt fur Informatik". - The AS announces 6144 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 147 observed neighbours; this high neighbour count relative to the modest address inventory indicates a transit or peering-heavy role for the cantonal network.
- Traffic from this AS consists of internal government services, administrative endpoints, and inter-cantonal or federal connectivity for the Canton of Zug.
Notable
- Registrants for both announced IPv4 prefixes align with the AS holder, listing "Kanton Zug" and its IT department ("Amt fur Informatik") as the administrative and technical roles.
- The address inventory is compact, comprising two contiguous IPv4 blocks (193.134.16.0/20 and 193.134.8.0/21) and a single IPv6 prefix (2a10:8244::/30), typical of a regional government entity managing its own IT estate.

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 1,781 prefixes, as published 2026-10-16. 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.
