Does anyone know how to or where I can check like 10,000-25,000 domains at once to see if they are available to register?
I'd start with ScrapeBox to do a first run, you may need to further check those that are available, but it would get through those pretty fast if you have enough proxies loaded.
How? I have scrape box. It does not have that option. There is something in the keyword part but there is not option to allow you to put domains with tlds in there.
I use domainhuntergatherer. It's paid but I don't know any quicker / more efficient way of finding expired domains.
Yep Domain Hunter Gatherer also supports checking of every TLD and comes with a bunch of credits for checking Moz and Majestic stats (50k a month as standard).
You didn't say what extension you were after. SB is limited to about 4 extensions. It works for me on 2.x latest.
If you had spent 10 seconds to specify the TLD's of the domains you want to check we might have been able to help you... There's not a magic solution to this. Each TLD has a different hostmaster with different requirements (some blocks you if you query too quickly while others don't care at all).
