GeoDNS - In 2008, DNS created the first plug-and-play geolocation solution, expanding the reach and cost-effectiveness for websites, applications and marketers to geotarget their content, traffic and advertisements. Our rules-based system turned the problem of integrating location services on its head with a web based model that allows anyone to customize URL responses on the fly, without the need for on-page code or specialized programming knowledge. DNS is unique in offering the most precise geolocation in the industry, with city-level targeting available in more than 200 countries as a standard feature on all accounts.
