How does the network recognize a device when it is plug into the network? I have two sets of IP address, Class C address 165.xxx.xxx.xxx for computer and other network device and Private address 10.xxx.xxx.xxx for VoIP use only. How does it work when I plug my IP phones into the network it give me a 10.x address and when I plug my computer into the same jack it gives me a 165.x address? How does this work, where is the setting to tell the device to pickup different address? Thanks in advance.
