Easy;-At command prompt, type "arp -a" then enteryou get lists a number of MAC addresses with the associated IP addresses. Since you have Arduino MAC address, scroll down the list to find the associated IP address.
Thanks. It seems to work on a PC. Is thers any app that will list address table on a tablet or smart phone? I would like to ultimately use a smart phone to join the local wifi network, find the IP address of the arduino, and direct my smart phone web browser to arduino.
I prefer brainless solution. Here is my way;- Open router admin web GUI page, It is there! It might be dependent on router OS.
Thanks! The router is going to be a 3G Android device serving as a wifi hotspot inside of a weather-proof box so I prefer the hard ways. Maybe an easy way is to try "all possible" addresses or just look at your own address when you connect to this 3G Android device. Say it's 192.168.1.3, then guess 192.168.1.2 for arduino
