AS6394 DATA-BROADCASTING

DATA-BROADCASTING is now held by Intercontinental Exchange, Inc. (ICE), the Atlanta-headquartered exchange and financial-data group that owns the New York Stock Exchange. The handle records the original registrant — Data Broadcasting Corporation, a market-data distributor whose business line descended through Interactive Data into today's ICE Data Services.

What it's used for

• Corporate and market-data infrastructure for ICE's data business.
• A very small footprint: two /24s out of 156.48.0.0, on the order of five hundred IPv4 addresses.

Notable

This is enterprise address space belonging to a financial-data firm, not an ISP or a hosting provider. Addresses here front data-distribution and corporate systems; there are no subscriber pools. The tiny announced count relative to the low AS number is characteristic of a 1990s registrant that never needed to grow its public IPv4 footprint.

Interesting

The registry handle is a fossil. DATA-BROADCASTING names a company that stopped existing under that name decades ago, but the AS number and its address blocks followed the market-data business through each acquisition and now sit inside one of the world's largest exchange operators.
