can a pc on network have same ip n mac address as that of another pc on the network ?

Question

if yes then please tel me wat sought of problems wil we hav to face in that case i would appreciate if someone answers the question thanx a lot

Answer 1

each nic does have a burnt in mac address. it can be emulated, spoofed, by someone that knows what they are doing but it is not the normal problem. ip address conflicts can cause problems all the time in large or static networks. on networks were the ip address is given to you

go to start run
type cmd
ipconfig /release
ipconfig /renew

the two steps make it more likely that the conflict will be removed
plus do it on both computers with the conflict

Answer 2

An Internet Protocol (IP) address is a unique 32 bit (4 byte) address each computer on the internet must have, it's an identifier for each computer, and is the way of sending and retrieving data.

You can configure 2 PC's to have same IP manualy but both won't come onto the network.

MAC address is also known as Hardware address can never be same and all the network cards have unique MAC address.

The MAC address is a unique value associated with a network adapter. MAC addresses are also known as hardware addresses or physical addresses. They uniquely identify an adapter on a LAN.

MAC addresses are 12-digit hexadecimal numbers (48 bits in length). By convention, MAC addresses are usually written in one of the following two formats:

MM:MM:MM:SS:SS:SS


MM-MM-MM-SS-SS-SS
The first half of a MAC address contains the ID number of the adapter manufacturer. These IDs are regulated by an Internet standards body (see sidebar). The second half of a MAC address represents the serial number assigned to the adapter by the manufacturer.

Answer 3

No. If the IP address is the same you will recieve error's. MAC address cannot be the same either. IP error's recieved will vary depending on if you are on a peer to peer network, Is there a router? Or a server network with DHCP?. MAC address is assigned when the NIC card is manufactured. You could end up with the same MAC address in the early days of networking, however the chance's of recieving 2 NIC cards with the same MAC address are pretty slim. (billions to 1) You can check MAC address with the ipconfig/all comand.

Answer 4

If... you had two computers with the same IP and MAC address on the same network you would get conflict errors that would have to be corrected. This is a situation that could not exist in the real world.

Answer 5

I don't know any utility for it. But this task does by a protocol by ARP name. this protocol send a packet by broadcasting that have mac address and it's IP. After that that mac receive it, send a packet to that IP that contains IP.

Answer 6

you can do it by config it manually but it cause conflict and two PC can't work correct, ex: you try connect to pc A but you connect to pc B. So easiest way is you should setup a DHCP Server, it will release IP automatically to other computer in network (client must set as: Obtain an IP address automatically)

Answer 7

no way a computer can have ip address in same network, but can have same ip address in different network(private ip address).... and mac address is unique for a computer(in the whole world) it depends on the NIC (network interface card) in the mother board.......

Answer 8

no i do not believe so each pc needs it own IP address or it will cause a conflict. you can set the setting to automaticaly get an ip address or u can set them as a dynamic IP and assign an ip in your network.

Answer 9

You will have so many conflicts. Change the IP. If the MAC is built into the NIC, then replace the NIC.

Answer 10

Our home network uses PC and MAC's and have no problems.
