How to set a Manual IP address in Mac OS X
There are times where you’ll want to manually set your IP address in Mac OS X, so how do you do it?
* Launch ‘System Preferences’ from the Apple menu (or Spotlight)
* Click on the “Network” icon
* In the lower right, click on the ‘Advanced’ button
* In the pulldown menu next to “Configure IPv4″ select “Manually” (or DHCP with manual address, if that’s what you need)
* Fill in the IP address, subnet mask, and router, as appropriate to the network you are accessing
* Click ‘OK’
* Click ‘Apply’
That’s it! Not too hard right? Computer users can sometimes be funny, my cousin called me frantically asking me how to manually set his IP address, apparently due to the current network conditions at his lab this was a requirement to be able to have internet access. The guy is brilliant, he’s studying for his PhD but he just automatically assumed that setting a manual IP address was complicated, after I walked him through this, he laughed. Don’t be afraid to get your hands a little dirty! Things on a Mac are almost always easier than you think.
