Someone asks me via contact form how to check potentially hundreds of domains for availability at once, as it’d be a huge waste of time to check them one by one. For example, when you need to check if these 50 domain names are still register-able: californiainsurance.com, newyorkinsurance.com, virginiainsurance.com, … and so forth, you need a bulk search tool for available domains.
While an AJAX whois tool gives instant results for all major TLDs, a bulk domain name search tool queries for the availability of all the domains at once in larger volumes that’s preferably no less than 100 in a batch.
Dynadot free bulk domain search is just the tool you need in a situation like this. You can generate a list of most wanted domains, in 100, and input them batch by batch to their domain bulk checker.
Register an account at Dynadot, head to: Domain Names –> Bulk Search and you should be able to check 100 domains at a time.
