Summary
Open Circle AG
business cloud swiss smb
OPEN-CIRCLE is operated by Open Circle AG.
What it's used for
- The address space carries corporate and cloud infrastructure, evidenced by netnames
CH-OPEN-CIRCLE-20190214andCH-OPEN-CIRCLE-20160115registered to Open Circle AG. - The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 50 observed neighbours; this ratio of limited address space against a high neighbour count indicates a transit or interconnection role rather than a large-scale access network.
- Traffic from this AS consists of web and API endpoints, virtual servers, and managed workstations for small and medium-sized enterprises, supporting the company's "Swiss Business Cloud" and digital sovereignty services.
Notable
- Registrants for both announced IPv4 prefixes are Open Circle AG, matching the AS holder and confirming direct ownership of the address space.
- Open Circle AG was founded in 2001 as Young Solutions AG and has since evolved into a provider of modular IT solutions and cloud infrastructure for Swiss businesses.
- The inventory consists of two /22 IPv4 blocks and a single /29 IPv6 prefix, representing a compact, internally managed corporate 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: 445 networks and 1,817 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.
