Domain Name Search
Check domain name availability across dozens of TLDs, with the registration year of every taken name.
How These Results Are Checked
Each extension is queried against its own registry using RDAP, the protocol that replaced WHOIS. RDAP returns the registration date, expiry date, and registrar for any name that is already taken.
- Registered
- The registry holds a record for this name. Where the registry publishes them, the registration year and expiry date are shown.
- Possibly Available
- The registry reported no record for this name. Confirm at a registrar before you plan around it — premium, reserved, and blocked names can still be unbuyable.
- Unknown
- The registry did not answer in time, rate-limited the lookup, or publishes no public data. It is never a claim that the name is free.
Some registries — including .io, .co, .me, .de, and .us — run no public RDAP service, and others meter how many lookups one visitor may make. Those extensions are checked by looking for a nameserver delegation instead: the status is reliable, but no registration date is available for them.

Understanding Domain Name Search and DNS Tools
A domain name search tool helps users find and verify the availability of domain names on the internet. Domain names are human-readable addresses like example.com that map to IP addresses via the Domain Name System (DNS). DNS is a hierarchical system that translates these domain names into numerical IP addresses, allowing browsers to locate websites.
When you want to create a website or establish an online presence, choosing a unique domain name is essential. Domain name search tools query domain registries to check if a desired name is already registered or available for purchase. This process prevents conflicts and ensures your chosen name is unique and accessible.
Common situations where domain name search is used include:
- Launching a new website or business and securing a matching domain.
- Checking availability of domain names for branding or marketing campaigns.
- Verifying domain ownership or expiration status.
- Researching alternative domain extensions (TLDs) like
.net,.org, or country-specific domains.
DNS tools more broadly include utilities to diagnose DNS records, troubleshoot connectivity, and verify domain configurations. Domain name search is a fundamental step before registration, while other DNS tools assist with ongoing domain management and technical troubleshooting.
What is Domain Name Search?
Domain name search is the process of checking if a specific domain name is available for registration. Domain names serve as easy-to-remember addresses for websites, translating into IP addresses through the Domain Name System (DNS). Before registering a domain, you need to confirm that it is not already taken by someone else.
When to Use Domain Name Search
- Planning to launch a new website and securing a unique domain name.
- Checking availability of domain names for branding or marketing purposes.
- Verifying if a domain has expired or is available for purchase.
- Exploring alternative domain extensions if your preferred name is unavailable.
Common Mistakes to Avoid
- Assuming a domain is free just because it doesn’t appear in search results.
- Failing to check multiple domain extensions to protect your brand.
- Overlooking trademark conflicts when selecting a domain name.
Technical Context
Domain name search tools query domain registries to determine if a domain is registered. This is a crucial first step before domain registration. DNS tools more broadly include utilities for managing and troubleshooting DNS records, but domain search focuses specifically on availability checks. Using these tools helps ensure your domain name is unique, accessible, and legally safe to use.
