  • PyFunceble

    The tool to check the availability or syntax of domain, IP or URL.

    Assuming we can test 100 domains per second, that's about 3 hours non-stop for a combined list of a million domains, merely testing for nxdomain without actually trying to make any http get. PyFunceble do http get, and they pointed out it could take days, with Dead Hosts service available for source lists to save us from wasting so much cpu clock. So it seems it's already being done for us by the list maintainers.
