How to assign a static IP to a virtual switch?

Question

Computer networks

Good evening!
Small network of 40 computers. domain network. 192.168.88.1
One domain controller aka DNS server:
192.168.88.2
255.255.255.0
192.168.88.1
192.168.88.2
8.8.8.8
It was necessary to install the Hyper-V role
After installation, a virtual switch naturally appeared and received IP 192.168.88.207
Now 40 computers do not see your controller (when you log in), since they have static DNS settings 192.168.88.2
Tell me how to assign 192.168.88.2 to this virtual switch?
With manual settings, virt.comm
192.168.88.2
255.255.255.0
192.168.88.1
192.168.88.2
Internet disappears
Do not kick, how to be in such a situation?
