Every individual or business with an internet service plan will have two types of IP addresses: their private IP addresses and their public IP address. The terms public and private relate to the network location — that is, a private IP address is used inside a network, while a public one is used outside a network.
Can a system have multiple IP address but one MAC address?
Yes you can have multiple IP addresses assigned to the same MAC address.
Does MAC address and IP address have different roles?
The main difference between MAC and IP address is that MAC Address is used to ensure the physical address of the computer. It uniquely identifies the devices on a network. While IP addresses are used to uniquely identifies the connection of the network with that device takes part in a network.
Can the same device have different MAC address?
Can a device have more than one MAC address? Yes. For each network interface in your device, there is a unique MAC address associated with it. So if your laptop has both an Ethernet port and Wi-Fi built-in, you will see two MAC addresses in the system configuration.
Can 2 computers have the same IP?
An IP address conflict occurs when two or more devices on the same network are assigned the same IP address. Because of this setup, no two devices can have the same IP address on one network. If this happens, the network becomes confused by the duplicate IP addresses and can't use them correctly.

Can two devices have the same IP on different networks?
Unless your router malfunctions, two devices should never get the same IP address under this system. Your router knows which IP addresses are already in use and won't give them out twice. More commonly, an IP conflict can occur when you assign static IP addresses on your network.
What happens if two hosts have the same MAC layer address or same IP address in a LAN?
Both hosts will receive some packets. Neither will function correctly because neither can receive enough packets to create and maintain a TCP connection. They will definitely not exchange any packets with each other.
What happens if two hosts share the same IP address but not the same MAC address on a LAN?
You will end up with IP conflicts and will see issues where some frames/packets will travel to one device and some frames/packets to the other. The other issue you will see is the mapping between MAC addresses and IP addresses.
Can a server have 2 IP addresses?
Yes you can have more than one IP address when using a single Network Card. Setting this up is different in each Operating System, but may involve creating a new Network Interface. This can look like a unique connection but will be using the same Network Card behind the scenes.
Why we need both MAC and IP address?
MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
What is the main difference between IP address and MAC address?
The IP address of a device mainly helps in identifying the connection of a network (using which the device is connecting to the network). The MAC Address, on the other hand, ensures the computer device's physical location. It helps us to identify a given device on the available network uniquely.
What do you know about MAC address and IP address of a computer differentiate both in detail?
MAC Address stands for Media Access Control Address. IP Address stands for Internet Protocol Address. MAC Address ensure that physical address of the computer is unique. IP Address is a logical address of the computer and is used to uniquely locate computer connected via a network.
How many MAC addresses does a device have?
While most desktop computers have only one MAC address for the wired network card, most laptops should have two MAC addresses--one for the wireless network card and one for the wired network card. It is important that both wired and wireless MAC addresses be recorded.
Can a device get a new MAC address?
The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing.
How many MAC addresses are possible?
This 48-bit address space contains potentially 248 (over 281 trillion) possible MAC addresses. The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers.
How can another computer have the same IP address as mine?
Ever get an IP address error message when turning on your computer or taking it out of sleep mode? This occurs when two computers on the same LAN network end up with the same IP address. When this occurs, both computers end up not being able to connect to network resources or perform other network operations.
Should all my devices have the same IP address?
Rather than your Internet service provider assigning a unique public IP address to each device in your home – you would need an additional IP address every time you bought a new computer, tablet, smartphone, game console, or anything else – your ISP generally assigns you a single IP address.
Does VPN change IP address?
A VPN replaces your actual IP address to make it look like you've connected to the internet from a different location: the physical location of the VPN server, rather than your real location. This is just one reason why so many people use VPNs.
What happens when two devices have the same IP?
For a system to communicate via a network, it must have a unique IP address. Conflicts arise when two devices are on the same network trying to use the same IP address. When this occurs, both computers end up not being able to connect to network resources or perform other network operations.
What happens when two computers use the same IP address?
If two computers on the same network have the same IP address the results are unpredictable. It is possible that neither computer will have a working network connection. Other possibilities include: Only one device is able to access the network.
Can two hosts have the same MAC address?
It's possible for two hosts to have the same MAC, due to spoofing, a mistake during manufacturing, or willful negligence on the part of the manufacturer. So, 1) In general, an Ethernet switch keeps a table of which MAC addresses are attached to which ports.
What happens if two hosts have the same MAC layer address?
2) If NIC's with the same MAC address are connected through a switch and those two hosts try to communicate with each other.
What is spoofing a MAC address?
MAC address spoofing is an attack that changes the MAC address of a wireless device that exists in a specific wireless network using off-the-shelf equipment. MAC address spoofing is a serious threat to wireless networks.
