Common questions
- How do I check if a domain name is available?
- Enter a name in the domain search box. RollDomains checks availability across hundreds of TLDs and shows registration pricing for open names. You can filter by extension or search a full domain like example.io.
- What if the .com I want is taken?
- Try alternative TLDs (.io, .co, .net), add a relevant keyword, or use our domain generator for ideas. WHOIS lookup shows who owns a taken name if you want to pursue a purchase.
- Can I search multiple domain extensions at once?
- Yes. Use TLD filters or quick-pick buttons to check several extensions in one search. Bulk search is also available for checking many names at once.
- Is domain search free?
- Yes. Searching availability and comparing TLD pricing on RollDomains is free. You only pay when you register or transfer a domain.
