How to Check a Domain?

Domain name lookup is essential to determine if a domain name is available for registration or if it is already taken. You can also perform a domain check to gather information about the domain, such as its registration details, ownership, and expiry date. Here's how to check a domain:

1. Using Domain Lookup Tools

To check if a domain is available or to gather information about an existing domain, you can use domain lookup services. Popular domain lookup tools include:

• WHOIS Lookup: WHOIS databases store information about domain names, such as the owner, registration dates, and contact details. You can use a WHOIS lookup tool to query a domain’s registration details. Some popular WHOIS lookup tools are:
  • F5 PLUS
  • ICANN WHOIS
  • Whois.com
  • DomainTools

2. Checking Domain Availability

If you want to check if a domain is available for registration, you can use a domain registrar or a domain search engine. These platforms allow you to search for domain names and instantly tell you whether the domain is available or already registered. Some popular domain registrars include:

• F5 PLUS: https://www.f5plus.com

3. Performing a WHOIS Query

A WHOIS query will give you detailed information about an existing domain. It may include:

• Registrant Information: Name, address, and contact details of the domain owner.
• Registrar Information: The company that registered the domain.
• Creation and Expiry Dates: The domain's creation date and expiration date.
• Nameservers: The DNS servers associated with the domain.

To perform a WHOIS query, simply:

• Go to a WHOIS lookup tool (e.g., ICANN WHOIS).
• Enter the domain name you want to look up (e.g., example.com).
• The tool will display the registration details and availability status.

4. Checking Domain History

If you're considering purchasing an already registered domain, you may want to know the domain's history. This can include its previous ownership or any potential involvement in malicious activities. Websites like DomainTools provide domain history reports that give you a complete overview of a domain's past.

5. Using DNS Lookup

For additional information about a domain's functionality (e.g., checking if it has a valid website or email setup), you can use a DNS lookup tool. This shows DNS records such as A records (IP address), MX records (mail servers), and CNAME records (aliases).

Some popular DNS lookup tools include:

• MXToolbox
• DNSstuff

6. Additional Checks for Domain Valuation

If you're looking to assess the value of a domain name (for resale, business, or branding purposes), there are tools that can estimate its worth based on factors like traffic, backlinks, and keyword relevance. Some tools include:

• EstiBot
• Sedo
