Summary

KLA Corporation

United States of America · AI-generated

business semiconductor corporate internal

KLA is the autonomous system for KLA Corporation, a semiconductor equipment manufacturer.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames like KLA-ANN-ARBOR-MI, KLA-TAIWAN, KLA-ISRAEL, KLA-SINGAPORE, KLA-BELGIUM, and KLA-EMEA-DC-VANTAGE.
  • The AS announces 3840 IPv4 addresses across 11 prefixes with 14 observed neighbours, a ratio consistent with a finely subdivided internal corporate estate rather than an access or transit network.

Notable

  • Registrants largely align with the announcer, including KLA Corporation, KLA Corporate, and regional entities like KLA-Taiwan and KLA Corporate - Israel.
  • One prefix, 192.118.26.0/24, is registered to Orbotech Ltd.; Abuse-C Role with netname ORBOTECH-BLOCK-1, reflecting KLA's acquisition of Orbotech.
  • The inventory consists of multiple /24 blocks and two larger blocks (192.146.8.0/22 and 192.146.24.0/23), all located in the United States.

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 1,845 prefixes, as published 2026-10-31. 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.
