OpenDNS Announces DNS-O-Matic: Free Service to Simplify Residential ISP and Small Businesses’ Dynamic DNS Service

OpenDNS Announces DNS-O-Matic: Free Service to Simplify Residential ISP and Small Businesses’ Dynamic DNS Service

San Francisco (PRWEB) December 3, 2007

OpenDNS, the award-winning DNS service that makes the Internet safer, faster, smarter and more reliable, today unveiled DNS-O-Matic, a free service aimed at helping users update the dynamic IP addresses assigned by their Internet Service Provider (ISP). Dynamic IPs are standard for residential Internet connections and hinder advanced network applications that are commonly used. OpenDNS is the world’s largest, fastest-growing DNS service.

DNS-O-Matic is poised to solve a problem plaguing hardware companies, service providers and Internet users everywhere. Many important Internet applications require knowing a customer’s current IP address, which may change from time to time. DNS-O-Matic is the standard that allows users to automatically notify any supported service provider of an IP address change. For hardware companies, dynamic DNS service providers and software developers, supporting a single service gives customers choice of dynamic DNS services and allows hardware manufacturers to implement only one protocol to support all existing Dynamic DNS services.

People with dynamic IPs can start benefiting from DNS-O-Matic immediately by visiting the site and setting up a free account. From there, adding a new service is simply a matter of adding it in their interface, no longer needing to download a new piece of software for every dynamic IP-dependant service they use.

“The idea for DNS-O-Matic was born of a need we had for our own service,” said OpenDNS CEO David Ulevitch. “When a customer’s IP changes, their configuration must be updated with the change. This is unacceptable for schools, libraries, businesses and residences that have Web content filtering, and our other features enabled. We approached the problem the way we approach everything: with the idea that working together is usually the best option for service providers and end users. In the case of DNS-O-Matic, everyone benefits.”

“We see the DNS-O-Matic service as a key value to our customers who are in highly mobile and constantly changing environments,” said Gary Oliverio, VP Marketing and Founder of CradlePoint, manufacturer of docking cradles, cellular routers, and software platforms that facilitate secure mobile computing in the Web 2.0 world. “With DNS-O-Matic, OpenDNS helps us broaden our ability to provide complete solutions.”

“DNS-O-Matic takes a challenging problem for the industry and offers a simple solution for users, software developers, and DNS service providers,” says Sam Norris, CEO of ChangeIP, provider of world class dynamic DNS services to more than 175,000 customers.

Among the services supported by DNS-O-Matic updates are: Afraid.org, BroadbandReports.com (Line Monitoring), ChangeIP, DNS Made Easy, DNS Park, DtDNS, DynDNS, DynIP, EasyDNS, EditDNS, EveryDNS, No-IP, OpenDNS, SecuritySpace, TZO, WorldWideDNS, ZoneEdit and more to come.
