Summary

D. E. Shaw & Co. LP

United States · AI-generated

enterprise legacy

SHAW is D. E. Shaw & Co. LP, the quantitative investment and technology firm headquartered in New York City. Despite the handle, this is not the Canadian cable operator Shaw Communications.

What it's used for

  • Corporate and trading-infrastructure networking for a firm that runs computationally intensive quantitative strategies and the systems research behind them.
  • Enterprise connectivity for offices and the firm's own compute estate, not a service sold to outside customers.

Notable

  • This is private financial-industry address space. Nothing here is consumer or hosting traffic.
  • The footprint (roughly 70,000 addresses) is unusually large for a private firm and reflects an early registration rather than present-day need.
  • D. E. Shaw has held the number since the mid-1990s. The organization record was refreshed in a later registry cleanup, but the AS number was not reissued to a new holder.

Interesting

  • The bare SHAW handle regularly causes AS4195 to be mistaken for a telecommunications provider. It is a hedge fund, and the low AS number is a reminder of how early some Wall Street quant shops built serious in-house network and compute capability.

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 1,782 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.
