Why is my iOS simulator trying to access irs.gov while debugging my app?

I'm developing an app that has absolutely nothing to do with anything other than specific external audio-related hardware. While running my app in the iOS simulator, I got a message from my LittleSnitch (that's a firewall) that the process geod (iOS) is trying to access irs.gov. As if that wasn't enough, the next attempt was to azadiradio.org. I blocked both but I'm wondering... what the actual hell is going on within my iOS simulator?
