Hi friends,

I want to know whether any methods are available to get machine IP  
address using MAC address. Thanks in advance,

Yes, there are. You can send a RARP packet on the network segment to  
which that machine is connected; or you can read the ARP table of any  
machine which is connected to the same network segment (e.g. using  
SNMP).
