Is it valid to have two network adapters on the same PC have the same network portion in their IPv4 address? If not why is my DHCP server doing so and how should I setup my DHCP server to have it give each different adapter a different IPv4 network assignment?
I have a Windows 7 PC with a Wired Ethernet and a Wireless LAN connection. The two network adapters are getting their IP address from the same DHCP server. The server is handing out addresses that are on the same network: specifically the 192.168.100.0 given the subnet mask of 255.255.252.0.
