Assuming the form of IP is A.B.C.D
To meet

 A==10 | | (A==172 & amp; & B>=16 & amp; & B<=31) | | (A==192 & amp; & B==168)

Is the private IP network

If such as my home computer connected to the router (automatically assigned address), at the same time connected to wifi will have several such address

(wifi IP phone even) & amp; & (computer even wifi or routing assigned address)
This address is only 192.168

What is your demand? Find the WIFI IP? Or find all computer LAN IP?

In order to make the computer open listening (don't know the IP),
Mobile phone or another computer connection.

Connection at this time I want to want to have the following kinds:
1 two computers had the same router (router assigns two IP addresses)
2 a computer had a router, another had wifi router (router assigns two IP addresses)
3 computers connected to the router (automatically assigned address), at the same time connected to wifi, another had a router wifi
When the host opens to monitor what IP?

By the fixed a computer to act as a server?
As long as even under the same router, you can direct communication, your server WIFI address and the address of the Ethernet cable is no problem,
Have two choices, one is for the computer allocation of fixed IP address, DHCP static reservations, another option is confirmed by the client and the server communication IP, server send broadcast to inform the client own IP, or UDP broadcast for the client by the server, the server after received reply,
