If you execute that command in your Terminal, you should get something similar.Īs for your DNS, what is happening is that your phone/tablet will send the DNS request to your Mac, and then your Mac will take that request and send it to the DNS hosts you have listed. This is a virtual interface that was created on the WLAN adapter.

When you enable Internet Sharing, it turns your Mac into a DHCP server and DNS forwarder - basically, it turns into a router along with NAT and firewall services to boot. I even tried it on a Windows Phone - here's the screenshot of the settings the phone got from my iMac: To verify this, I setup Internet Sharing over WiFi with my Ethernet adapter as my primary connection and got the exact same results you did (the IP addresses varied some, but it's irrelevant). What you are seeing is completely normal. when I check on my iPhone what DNS it hands out, it shows If relevant, here is my Ethernet settings: I'm not sure if the Internet still wouldn't work on other devices since I'm not using them. I've upgraded my OS to El Capitan since I made those initial observations, but I checked again and it is still putting out that same DNS server. That was a workaround for my iDevices that let me make that change but not for other devices. ![]() In the past I had problems where I couldn't use the Internet on the devices that were connecting to the shared WiFi unless I manually set the DNS server on each wireless device (not the Mac) to some actual server like 8.8.8.8. ![]() It's not even the home router, something about the Mac I think. Should that be? That's not any actual DNS server, that's something local to the network. However when I check on my iPhone what DNS it hands out, it shows 192.168.2.1. I have a MacBook Pro and I share its Ethernet connection to my iPhone and iPad as well as other wireless devices (enabling Internet Sharing in the Sharing preferences).
