Dynamic Network Services, Inc. is a network services company best-known for its free DynDNS dynamic DNS service, which allows users to have a subdomain that points to a computer with regularly-changing IP addresses, such as those served by many consumer-level Internet service providers. An update client installed on the user's computer, or built into a networked device such as a router or webcam, keeps the hostname up to date with its current IP address. Another popular free service provided by the company is internet content filtering. DynDNS also offers paid domain registrations, recursive DNS, e-mail forwarding and redirection, SSL certificates, network monitoring, URL redirection, and Virtual private server hosting.


Dynamic Network Services Inc. (abbreviated Dyn Inc.) was started in 1998 as a free service. It has since expanded to nearly four million users and is expanding at an ever-increasing pace. The company now also offers premium services for consumers (DynDNS®) and enterprise businesses (Dynect®).

The company became a Massachusetts limited liability company on October 24, 2001.[1] In July, 2003, the company reorganized into a Delaware corporation.[2]

In 2006, the company moved again to a location on Elm Street in Manchester, New Hampshire, with nearly triple the space of the previous office.

The company launched the Dynect® Platform in October 2007 in response to a growing need for enterprise solutions from their DynDNS® customer base.

In August, 2008, the company began offering Virtual private server hosting[3] in a private beta offered to survey takers. Spring Server℠ VPS became available to all users in September, 2008.

Buy outs - Controversy[]

On April 2010 Dyn buys EveryDNS and in August 30 EditDNS. That way the free DNS market with only a few players. Some users have complained about the mergin process on the case of EveryDNS and the users of EditDNS have expressed concerns about that company managing now their domain zones.

Third-party usage[]

The DynDNS® update API is used by many other businesses and systems. Released as an open system, the intent was to allow easy control by third-party developers. Since its inception in 1998, the DynDNS® API has been used by a number of different applications and companies, including Netgear,[4] OpenDNS, Norton DNS[5], and No-IP[6]

A number of router manufacturers have adopted the API to include update capabilities in their devices, including Linksys, Netgear, D-Link, Cisco, Sonicwall, Belkin, Acorp and many others. Due to the open nature of the API, clients are not regulated and therefore it is impossible to track how many different devices support the API.

There is a certification program available for third-party products, but certification under the program is not required for use of the API.

In May 2004, the company started providing DNS services for top-level domains, starting with the .cx TLD. DynDNS® is also the sole Domain Name System (DNS) provider for the .coop TLD.

The company also provides DNS for several other TLDs: Christmas Islands (.cx), Mauritius (.mu), Solomon Islands (.sb), as well as of the Democratic Republic of Timor-Leste (.tl).
