Summary

CirrusLab

Switzerland · AI-generated

research education ipv6

CIRRUSLAB is operated by CirrusLab, a Swiss research and educational institution.

What it's used for

  • The address space carries a single IPv6 prefix, 2a10:2f00:160::/48, with no announced IPv4 addresses.
  • The inventory consists of 1 IPv6 prefix and 0 IPv4 prefixes, with 0 observed routing neighbours, indicating a small-scale, isolated network segment.
  • Traffic from this AS consists of research and educational endpoints, consistent with the operator's classification as an educational/research entity.

Notable

  • The registry holder is listed as CIRRUSLAB Christophe Gherardi, aligning with the AS handle CIRRUSLAB.
  • The address inventory is minimal, comprising only a single /48 IPv6 block, which suggests a limited scope of network deployment.

Reputation

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: 447 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.
