Domainers Glossary and Abbreviations

Domainers Glossary and Abbreviations
Glossary of terms and list of important abbreviations used frequently by domainers, people who own a large number of domain names. The glossary is still incomplete, but I am working on it. :)

If you are a serious "domainer", visit my Domain Names Research and Management Resources page which provides tools for domain typo suggestions and domain name analyser tools, expired domains/domain drop services, domain portfolio management services and information about how to monetize your parked domains. If you only want to register a domain for you or your business, check out my Domain Registration Resources and Services.

The domain name has to be unique for a TLD or ccTLD, for example "google.com": Google is the domain name and .com is the gTLD.
