Summary

McKinsey & Company

China · AI-generated

business corporate consulting

MCKINSEY is the autonomous system for McKinsey & Consulting Company Inc. Shanghai.

What it's used for

  • The address space carries internal corporate traffic, evidenced by the netname MCKINSEY-AP and registrant McKinsey & Company, Inc. across all announced prefixes.
  • The AS announces 1280 IPv4 addresses across 4 prefixes with 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and client capabilities professionals at the McKinsey Shanghai office, which serves as a hub for the Greater China region.

Notable

  • All registrants agree with the announcer, consistently listing McKinsey & Company, Inc. for the prefixes 156.107.160.0/23, 156.107.170.0/24, 156.107.179.0/24, and 156.107.181.0/24.
  • The inventory is finely subdivided into four distinct IPv4 blocks, reflecting site-by-site segmentation typical of a large corporate network.

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 1,778 prefixes, as published 2026-10-20. 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.
