I was scanning my network IPs. I found out that two different IP addresses were bound to the same MAC address. When I sent the ICMP echo requests to them, both of them responds back with echo reply.
It is rarely possible according to me.
I think it might be possible in case you are accessing internet on LAN.

Yes you can have multiple IP addresses assigned to the same MAC address.

Multiple ip address can be assigned to one network card, they can be from different ip range
Dear Nikhil Tripathi,
Yes, you can.
You may adapt multiple NICs. You may set multiple IP addresses to a single NIC. You may have multiple NICs each with multiple IP addresses.
Dear Sir:
I thing that U mean that the MAC has two IP in the same time. this is possible in tow cases as I thing, 1- it as Mr.Vikram Verma said, through a virtual machine like vmware work station that make PC in side PC.
2- there are two PC in your network have the same MAC, through some software, it possible to change your PC MAC and this case is the right as I thing. this case is used by some Hackers to connect to the network as a real user through taking same of the user's MAC jumping on the router mac table filter.
I guess you've already got your answer. I would just like to add another scenario where a device can have a multiple IPs. Consider a device(gateway) that connects two networks. It'll have two IP addresses one each to communicate with nodes in each network.
Additionaly, multiple interface cards (MAC addresses) can have a single IP address also.
Many OS provide a way to configure alias IPv4 addresses. And in IPv6 it is more default as exception. to have more than one IP address per NIC (MAC address) e.g. link local or global unicast address.
