About this network

DOWJONES-AS, the corporate network of Dow Jones & Company, the business-news publisher behind The Wall Street Journal, Barron's and MarketWatch, and a subsidiary of News Corp.

What it's used for

• Dow Jones's own enterprise networking: offices, newsroom and production systems, and the infrastructure behind its news and market-data products.
• Announces around two dozen prefixes, mostly /24s concentrated in 205.203.0.0/16 space, plus scattered legacy blocks.

Notable

• This is a media company's corporate AS, not a service provider. The address space is used by Dow Jones itself; there are no subscriber-style reverse names in it.
• The registrant address is Dow Jones's long-standing South Brunswick / Princeton, New Jersey operations site rather than the New York newsroom.

Interesting

• Dow Jones ran market-data and newswire distribution long before the public internet, so it was an early candidate for its own AS: financial publishers needed dedicated, reliable data paths to subscribers well ahead of most enterprises.
