How to Setup Ip Address in Mac

I have a linksys router WRTG54GS and I want to configure its ip address, it provides a unique IP address each of mac address, how to do this with the microphone software router?

Use Finder to open the applications folder, then Utilities, then terminal. When the terminal window opens, and the prompt appears, type ifconfig <ret>. The IP addresses will appear on the lines that start with "inet".

1. Open a terminal window so that you can type commands that are not on a menu. If you already have a terminal window open, skip to Step 5. Otherwise, click on the desktop background (not on any application).
2. The top menu bar should now say "Finder"; click on Go -> applications
3. On the applications menu, click on Utilities to open the set of commands that are on the Utilties submenu.
4. Under the Utilities folder, click on Terminal.
5. In the terminal window, type "ifconfig" then hit return.
6. In the output, there will be lines that include inet x.x.x.x netmask 0xffffff00 broadcast a.b.c.d
7. The IP address of the interface is the four numbers denoted by x.x.x.x in the lines described above.
8. There may be a line that says inet 127.0.0.1 netmask 0xff000000 This is the loopback interface, and always uses the IP address 127.0.0.1

• If you want to have terminal handier than looking it up in the finder, drag it to the tool dock
• When you are finished with the terminal, you can type exit, but this will not close the window. To do that, you need to use the top menu bar, terminal -> close
• This is for an Apple computer, for Windows, see the link below
• If you are behind a router, and you want to see your external IP address, go to one of the sites in the External Links
• Alternative Method: Click on Apple icon -> About This Mac -> More Info -> Network; IP Address is displayed on the right
• Alternative Method: Apple menu -> System Preferences -> Network; select your connection type from the drop-down menu and click TCP/IP. This also provides other information such as the subnet mask and router.

If you want constant local IP (called STATIC IP)
On your router you can assign an IP base on MAC address (not Mac address)

I dont exactly understand your question.

If you want to find your mac address, you have to open an MS-DOS window and to type ipconfig / all

Themacaddress is the physical address.
