Bypass host file and use real IP's of captcha services?

Hello, what exactly does this option mean in the captcha setup? "bypass host file and use real IP's of captcha services"

    Instead of relying on the entries in your host file to resolve a domain name to an IP, it is using your dns-server to resolve the IP.
    Thats useful to skip entries from emulation software that has entries in it.

    ok thanks anyway, still not sure I really understand this though. Is there a simpler way to explain this?

    Hmm lets see..
    When you contact a captcha service to get something solved, you do a request to e.g. www.cap-service.com.
    The domain www.cap-service.com needs to be resolved to an IP and that is done by two steps:
    1) the system checks if an entry is added in your host file that gives the IP
    2) if that fails, it will send a query to your default dns server that will the resolving by querying other dns servers.

    With the option "Bypass host file" it will skip step 1) and directly query the dns server.

    But why does the host file have these entries? It is used by emulation software to redirect traffic for a domain to somewhere else like a software that emulates a captcha service (GSA Captcha Breaker e.g. can simulate all services).

    So basically, if I don't have any emulation services set up then I don't need to check that box?

    correct.
