Hyper-V: IP configuration of virtual network adapter

Hi!

I have a Hyper-V-Host with 2 network adapters. One is for management of the host, one is for Hyper-V/virtual machines. What I don't understand is how the IP configuration of the virtual ethernet adapter on the host should be done. Everythings working fine without doing any configuration at all, but is this the best practice or does this have performance issues?

Thank you!
