About this network

BLOOMBERG-NET is Bloomberg L.P., the financial data, news and analytics firm behind the Bloomberg Terminal. This is Bloomberg's own global corporate and service network.

What it's used for

• Delivering Bloomberg's products to subscribers — Terminal sessions, market-data feeds, trading and analytics services — plus the company's offices, news operation and internal infrastructure worldwide.
• The anchor of the announcement is a 69.184.0.0/13, a very large block for a non-carrier, alongside 160.43.0.0/16 and 199.105.176.0/21. Financial market-data delivery is address-hungry: every Terminal endpoint, feed handler and regional point of presence needs reachable space.

Notable

• Enterprise at carrier-scale address volume — and the neighbour count is what separates the two. RIS sees 123 IPv4 prefixes / 594,176 addresses announced with only 28 observed BGP neighbours. Half a million addresses behind 28 peering sessions is not a transit business: a wholesale carrier moving that much space peers with hundreds to thousands of ASes because its revenue is its customer cone. Bloomberg's cone is Bloomberg.
• Twenty-eight neighbours is nonetheless a lot for an enterprise, and it fits the business: a market-data firm peers directly at exchanges and with the banks and brokerages it serves, because latency to the customer is the product.

Interesting

• Most of the 123 prefixes are /24s carved out of the 69.184.0.0/13. That granular deaggregation is how a globally-distributed private network steers traffic to the right region — the routing table doubling as a map of Bloomberg's footprint.
