FAQ
How do I check domain availability? Enter a word, brand idea, or full domain into Check Domain. The tool queries registry services across selected extensions and labels each result as available, registered, for sale, or needing confirmation.
Can I check all domain extensions at once? Yes, Check Domain allows you to search multiple popular extensions simultaneously.
Is a domain guaranteed when Check Domain says available? Availability is checked against registry RDAP services, but the final confirmation should be done at the registrar checkout.
Why does a DNS domain search differ from a registry result? DNS-based checks can be misleading; registry-backed RDAP checks provide more accurate availability status.
What does a WHOIS lookup domain record show? It shows public registrar, dates, nameservers, and record-source details when available.
Can I check the domain name registrar? Yes, WHOIS and RDAP views can reveal the registrar for registered domains.
Why compare domain registration and renewal prices? The cheapest first year may not be the lowest long-term cost; comparing both helps you make a more informed decision.
Does Check Domain save my searches? No, searches are processed on demand and the tool does not use accounts, a database, or tracking cookies.
