AS4195 SHAW

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.
