Live audio and IT Networking

I never thought going to school for IT Networking would help me out in the field of live audio where I have been working for the last 6 years.  We just recently upgraded the mixing console from an old analog console; huge with a million buttons and faders, about the size of a dinosaur, and weighed close to that too, to a digital console; sleek, brand new, about a quarter of the size, motorized faders, and the ability to control it via an Ipad.  This last feature is where my networking experience came into play.  The console actually has a ethernet port that allows you to hook it up to a wireless router. After it's hooked up it is necessary to configure the software on the mixer to display the subnet mask and gateway of the router as well as give the device a network address.  After that it's a matter of downloading the software for the Ipad and configuring the info you added into the console into the software.  It's an amazing feature to be able to go to any part of the room and hear how it sounds and be able to fix the mix.  It's also an amazing feature for fixing problems that arise on stage and being able to fix something, verify it is working and return it to the mix without having to fight through the audience.
