how to check your ip address in mac

Checking IP Address mac

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

Shortcut : Press Command + Space bar and type "terminal" into spotlight then return and type "Ifconfig" into the terminal and press enter.

Steps

1. 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. 1. 2
      On the applications menu, click on Utilities to open the set of commands that are on the Utilties submenu.
   2. 3
      Under the Utilities folder, click on Terminal.
   3. 4
      In the terminal window, type "ifconfig" then hit return.
   4. 5
      In the output, there will be lines that include inet x.x.x.x netmask 0xffffff00 broadcast a.b.c.d
   5. 6
      The IP address of the interface is the four numbers denoted by x.x.x.x in the lines described above.
   6. 7
      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
   7. 8
      Alternatively, in Terminal, type "netstat -p tcp" and hit return. This should return far fewer lines of text so you don't have to search too much for the information.
   
   
   
   

   Tips

   • 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.

   Warnings

   • When using an IP information site from an ISP that uses a transparent web proxy (such as AOL), be aware that the reported IP may be that of the ISP's web proxy and not your actual IP.

   
   

   
   

   
   

   
   

   
   

   
   

   
   

   
   

   Tips & Warnings

   • If the computer is part of a LAN, the IP address that shows is a private address (or internal). This IP address may be dynamic or static, depending on how your network is configured.
   • If the computer is connected directly to the modem, the IP address that shows will be your public IP address, the one the ISP has assigned to you.
   • You can check out your public IP (if you don't want to deal with your router) from several websites. Check out the Resources section for "What's My IP."

Delete option Mac

Mac will not delete the files with just delete of the button.

You have to click on "Command + Delete" to delete the files. These are moved to Trash folder. So you can restore them if needed. Empty the trash frequently if you dont need them any more.

There is no option to permanently delete the files in MAC with out moving to trash, like the "Shift + Delete" in windows. You need to have some automators installed if you want to have permanent delete option in MAC which I feel is not preferable.
