The Samsung Galaxy Ace S5830 is a nice mid-range Android phone running 2.2 Froyo with Touchwiz 3.0 on top. Sometimes it is useful to know what your device’s MAC address is and to locate it on the phone isn’t always that intuitive.
First, select the Settings application from the main menu and once loaded, select the Wireless and networks menu option. Once loaded, enter the Wi-Fi settings menu option. The trick now is to hit the menu button, which will bring up a new contextual menu with one of the options being Advanced. Click on Advanced and the new screen will finally read return your MAC address to you.
And now you know.
To find out what the current IP address assigned to your iPhone is turns out to be pretty simple if you know where to look.
First, select Settings from your SpringBoard. Next, select Wi-Fi from the resulting Settings menu. This results in a list of available networks being displayed under the Choose a Network… label. To the right of each listed network is a right-arrow icon. Find the network you are currently connected to in the list (it has a tick next to it) and click on the right-arrow icon.
This will bring up the detailed network information, listing among other things the IP address your iPhone is currently assigned with from that network’s DHCP server.
