Firefox DNS API

[Fatemah Alharbi]

Hello,

I’m using the latest version of Firefox on my Windows 10 Home edition and Linux Ubuntu 14.04 LTS desktops. I noticed that Firefox always sends two DNS requests: A and AAAA requests. I did an experiment to see which API is used by Firefox and found that the API getaddrinfo() does send 2 DNS requests on my Linux machine while it sends only one A request on my Windows machine. This doesn’t guarantee that Firefox always uses this API. Does Firefox uses multiple APIs depending on the OS? I would like to know which API does Firefox use when sending DNS requests.

Thank you for your help. This is part of my PhD research and I appreciate your cooperation.
