For a project that I've been working on, I need a really short domain. Preferably, it would have 6-4 letters, and I couldn't care less about which extension it uses or what the "text" of the domain is. Also, I'm on a budget, so it can't be that expensive.
Is there a list of domains that fit my requirements. I've tried domainr, but since I'm not looking for a specific domain, searching random combinations becomes tiring, and I don't think it's the best choice right now.
Does such a list exist?
