Bulk Domain Availability Scanning

[DomainAuction]

Is there such a service that will allow me to search the availability for a big list of domains I have generated? I generated 4,200 domains, all of them are .com's ... I can do 500 at a time at most registrar bulk checking services, but just curious if such things exist and where I can find then. Thanks in advance!
