Summary

Qihoo 360

China · AI-generated

security business china enterprise

QIHOO is the autonomous system for Qihoo 360, a major Chinese internet security and technology company.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames QIHOO and CTA-104-192-108-0-23 associated with registrants IRT-QIHOO-CN and QiHU 360 Inc.
  • The AS announces 82,432 IPv4 addresses across 14 prefixes and 1 IPv6 prefix, while maintaining only 6 observed neighbours, indicating a large internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal services, security endpoints, and corporate infrastructure supporting Qihoo 360's antivirus, browser, and internet security products.

Notable

  • Registrants are consistent with the announcer, primarily listing IRT-QIHOO-CN for the majority of prefixes and QiHU 360 Inc. for the 104.192.108.0/23 block.
  • The company was formerly known as Qihoo Technology Company Limited before renaming to Qihoo 360 Technology Co. Ltd. in 2010.
  • The inventory is dominated by the 101.197.0.0/16 block, with the remainder finely subdivided into /20, /21, /22, /23, and /24 prefixes within the 101.198.0.0/16 range.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
