Question 1

What is a domain name?

Accepted Answer

A domain name is the address you type into your web browser to visit a website, like "instantdomainsearch.com." It identifies a website on the internet, making it easy for people to find and remember. Like your home address helps people find where you live, a domain name helps people find your website. Our   domain search   helps you find available domains.

Question 3

What if the domain name I want is already taken?

Accepted Answer

If someone already owns the domain name you want, you still have several options: (1) Try a different extension: if someone owns "example.com," check if "example.net," "example.org," or other TLDs remain available. See the full list of available extensions at   domain extensions . (2) Create a variation: add a word, hyphen, or change the order of words to create a variation of your desired domain name. Our Domain Name Generator at   domain generator   suggests similar available domains. Our aftermarket domain search tool at   aftermarket domains   also helps you find similar, high-performing domains. (3) Contact the owner: the current owner might sell their domain. You can often find owner information by visiting the domain or using WHOIS lookup to locate the owner.

Question 5

What are extensions and TLDs, and which one should I choose?

Accepted Answer

A TLD (Top-Level Domain) represents the part of a domain name that comes after the dot, like ".com" or ".org." The .com extension ranks as the most common, but many others, such as ".net" or industry-specific extensions like ".tech" or ".shop," offer great alternatives. Our   domain extension explorer   helps you explore different TLD options.

Question 7

How much does a domain name cost?

Domain name prices vary by extension and registrar. Common extensions like .com typically cost $10–$15 per year, while newer TLDs like .ai or .io may cost $20–$80 per year.
