EveryDNS

EveryDNS.net was one of the world's largest free DNS management services, at one time providing DNS services for over 135,000 domains, for over a decade, ending in 2011.

EveryDNS was founded in June 2001 by David Ulevitch. On January 7, 2010, EveryDNS was purchased by Dyn Inc.

EveryDNS's web site was shut down on August 31, 2011 and all EveryDNS services were retired on September 9, 2011. Existing users were offered the opportunity to migrate over to equivalent services at Dyn Inc. starting 90 days prior to August 31, 2011.

EveryDNS offered services to webmasters who do not maintain their own Domain Name Services or who wished to use EveryDNS as a backup to their existing implementations. EveryDNS also offered dynamic DNS resolution, AXFR service, and domain2web redirection. EveryDNS supported SPF TXT records for donators.

Because of the danger of a distributed-denial-of-service attack on a domain name server, many companies outsource their domain name service management to companies such as Akamai. EveryDNS allows webmasters to use their servers for geographically distributed DNS service for free.

EveryDNS runs on an implementation of Daniel J. Bernstein's TinyDNS. EveryDNS uses MySQL and Perl to manage TinyDNS's hash tables. PHP is used to render the user interface, with information out of the MySQL backend database.

On December 2, 2010, EveryDNS dropped from its entries, citing DDoS attacks that "threatened the stability of its infrastructure". Everydns.com made the following public statement:
