To check this and there are generally three methods you can use to figure out which domains are being referenced when loading a website.
1) Use the Web Developers Console option in Firefox (Tools -> Web Developer -> Web Console) and load the site on a computer that is not using OpenDNS, as it will list all of the domains referenced when a particular webpage loads.

Right-click on any page element and select Inspect element.
On Windows and Linux, press Control - Shift - I keys to open Developer Tools
Control - Shift - J to open Developer Tools and bring focus to the Console.
Control - Shift - C to toggle Inspect Element mode.
On Mac, press ⌥⌘I (Command - Option - I) keys to open Developer Tools
⌥⌘J (Command - Option - J) to open Developer Tools and bring focus to the Console.
^⌘C (Control - Option - C) to toggle Inspect Element mode.
