How this code return more than one addresses?
How this code return more than one address?
You can have more than one network interfaces, LAN and WiFi for example.

Ok, Thanks for reply.
it does not return me the mac address which has not assinged any ip address, is there a way to get all mac addresses.
for example my machine shows this information when i run ifconfig -a command
ifconfig -a

but running this java code mentioned above i just get a single mac address instead of both which is 00155D3BF00F
It is working with me.
