AS8119 DTN-AS

DTN-AS belongs to DTN, LLC, a subscription data and analytics company

headquartered in Bloomington, Minnesota. DTN sells real-time weather, agricultural

and commodity/energy market information; the name is the old *Data Transmission

Network*, the Omaha company it grew out of.

What it's used for

• DTN's own corporate and service infrastructure. The reverse DNS on the announced space is entirely first-party: mail relays such as mail10-chi01.dtn.com and application hosts on dtnpf.com, the domain behind DTN Progressive Farmer.
• Delivering the market and weather feeds its customers subscribe to, from its own address space rather than from a public cloud.

Notable

• This is an enterprise network with a product attached, not a hosting or access network. There are no subscriber pools and no third-party customer prefixes; everything sampled resolves back to DTN's own domains.
• It is small and deliberately de-aggregated: about 6,100 addresses announced as 24 separate /24s, mostly out of 66.112.144.0/20 and 69.41.208.0/20, which suits a company that multihomes a handful of data centres for feed delivery.

Interesting

• The company predates the commercial internet: DTN began in the 1980s pushing market quotes to farmers over FM subcarrier and satellite receivers long before it delivered them over IP, and it has passed through Telvent and Schneider Electric to its current Swiss owner.
