Summary
Kaspersky Lab Switzerland GmbH
business security corporate
KL-AS is operated by Kaspersky Lab Switzerland GmbH.
What it's used for
- The address space carries corporate infrastructure, evidenced by netnames
CH-KL-20061123andKL-NET4registered to Kaspersky Lab entities. - The AS announces 2560 IPv4 addresses across 2 prefixes and 23 IPv6 prefixes, with only 3 observed neighbours, indicating an internal corporate estate rather than a transit or access network.
- Traffic from this AS consists of internal corporate endpoints, development environments, and security service infrastructure for Kaspersky's cybersecurity products.
Notable
- Registrants align with the announcer, listing Kaspersky Lab Switzerland GmbH and Kaspersky Lab Contact Role for the largest prefixes.
- The address inventory is finely subdivided into two IPv4 blocks and numerous IPv6 sub-prefixes, consistent with site-by-site segmentation for a large corporate organization.

Interconnection

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
