Although you use URLs to locate websites, your computer uses a completely different system. To it, www.komando.com is really 18.104.22.168. What makes this translation possible? A domain name system!
DNS servers compile lists of the URLs that match each IP address. However, most DNS servers have incomplete lists. This means your request could be filtered through many different servers before the site is loaded.
OpenDNS cuts out those middlemen. It keeps a gigantic list of domain names and funnels requests more efficiently to speed up Web browsing.
It doesn't just make your browsing faster, but it makes it safer, too! The service automatically detects phishing sites. If you stumble into one, OpenDNS blocks it.
It blocks porn and gambling sites, as well. You can set strict parental controls to limit what your kids see.
You don't even have to download any extra programs. Simply change a few of your connection settings and you're good to go. You can manage everything else through OpenDNS' site.
