Domain Name Terms
- A Record – This setting is used to point a domain name to a specific IP address.
- Country Code Top-Level Domain (ccTLD) – These are two-letter domain names that are associated with a specific country, such as .us for the United States or .ca for Canada.
- Cybersquatting – The process of registering a domain with the intent of preventing someone else from doing it, in the hopes to block them, steal traffic, or sell the domain to the other party at an inflated price.
- Domain Name – The name of your website, which follows the ‘www.’ in the URL, and also what follows the @ symbol in an email address. For example, in ‘www.Domain.com’ the ‘Domain.com’ is the actual domain name.
- Domain Name System (DNS) – The system that translates the numbers of an IP address into an easy-to-read domain name.
- Domain Flipping – The process of buying a domain name and selling it quickly for a profit.
- Domain Privacy – A feature often provided by domain registrars that hides the domain name owner information from the search results of a WHOIS inquiry.
- Extension – The last letters of a domain name, such as .com, that indicates the registry the domain is associated with, and as in the case of ccTLDs, the country
- Generic Top-Level Domain (gTLD) – The most common domain names, such as .COM, or .NET.
- Grace Period – The period after a domain name registration expires, but can still be renewed by the registrant, and before the domain is offered up for general sale.
- Internet Protocol (IP) Address – The string of unique numbers used to label a specific computer or computer server.
- International Corporation for Assigned Names and Numbers (ICANN) – The organization that coordinates the Internet’s naming system and regulates the domain industry.
- Misspelled Domain Name – Purchasing different, even incorrect spellings, of a domain name ensures that the audience looking for your business or brand online find your website, even if they type in your domain name with a few errors.
- New Top-Level Domain (nTLD) – TLD stands for “Top-Level Domain” and the “n” stands for “new.” A TLD is a string of characters that follow your domain name. For example, in the domain “myawesomedomain.com” the TLD, or domain extension, is .com. nTLDs are newer to the market, and include extensions such as .club, .design, and .news.
- Nameserver – A web server that stands in as a resource directory, sometimes for another server.
- Parking – The process of pointing a domain name to a page that is acting as a placeholder, used either as a space to advertise the sale of the domain or as a standby page before the owner starts using the domain name.
- Premium Domain – A high-value domain name that has been previously registered. They often contain valuable SEO keywords. Premium domain names have a stronger branding potential, are easier to remember, and attract more website traffic than standard domain names.
- Redirect – If a domain name is no longer being used, but is still registered, an owner can push any incoming traffic to a new, connected domain name instead.
- Redemption Period – After a domain name registration expires, and after the grace period, when the previous owner can still renew the domain, but usually at a higher price.

- Registrar – An accredited business or organization that sells domain registration services to the public.
- Registry – An organization that maintains and controls top-level domains (TLDs). They generally don’t sell domains directly to the public and instead sell domains through 3rd party registrars (like Domain.com).

- Reseller – An individual agent or affiliate of a specific registrar who sells domain name services.

- Subdomain – A separate address located under a domain name, such as store.brand.com.
