Do you know what TLD is? Don’t be too embarrassed. It stands for ‘Top Level Domain’ and to put it simply it’s what comes after the “.” in your domain name. It could be a .com, or a .net…and even and .us. If you’d like to be a nerd then you can find out more on Wikipedia. You can also get a brief history of gTLD’s (or Generic TLD’s) that were first introduced in the 80’s on the ICANN website. These included the ever popular .com, .net, .org, .edu, .gov, .int and .mil.
