I know a lot of people who say that .com stands for .company. In order to help some confusion, you should know .com actually stands for .commercial. To help you know what each .___ stands for, I made a list of internet domain suffixes.
.org – organization
.biz – business
.com – commercial
.net – network
.name – name
.mil – military
.gov – government
.pro – professions
.mobi – mobile device
.pro – professions
.aero – air transport industry
.int – international organizations
.tel – internet communication services
Also, every individual country has their own internet suffix, such as .co.uk for the United Kingdom and .us for the USA. Some others are: .aq – Antarctica, .ca for Canada, .cn for China, .jp for Japan, .es for Spain, and .cc for Cocos Islands. Hope this list helps you!
