How do IP address and MAC address work together?
The IP address is used to transport data from one network to another network using the TCP/IP protocol. The MAC address is used to deliver the data to the right device on a network.
Can two systems have same MAC and IP address?
Yes you can have multiple IP addresses assigned to the same MAC address.
Why do two devices have the same IP address?
Answer: If you access the Internet from a local network (LAN) in your home or business, it is possible that you share an IP address with other users. This is because, while you might use different computers or devices, you all use the same Internet connection.
Why is a MAC address needed?
The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Computer operating systems and broadband routers support viewing and sometimes changing MAC addresses.
Whats does MAC stand for?
MAC
| Acronym | Definition |

| MAC | Macintosh (slang for Apple computer) |
| MAC | Mandatory Access Control |

| MAC | Mid-American Conference |
How are MAC addresses and IP addresses used?
The IP addresses and Mac Addresses are used in tandem. Address Resolution Protocol is used to link the two together by resolving IP Addresses to Mac Addresses within the Link Layer within a single network. The MAC address gets a frame from one NIC card to the next. The IP address gets a packet from one Computer to the Server
Why are Macs and IPS rewritten along the way?
To attempt a simple illustration, consider the L2/L3 headers as a packet moves from the source IP (sIP) to a destination IP (dIP) and the source and destination MACs are rewritten along the way — fs=first-source and ld=last-destination, and r1-r3 are routers: Any L2 switches involved will not modify the MAC addresses.
Why does every computer have an IP address?
We know from previous posts that each computer has both an IP Address and a MAC Address assigned to it. But, why is this? If every computer in order to communicate with each other needed to be physically connected to each other, all networks either would become complicated very quickly or they would stay small.
What are the pros and cons of MAC address?
Here are pros/benefits of using MAC address: 1 It provides a secure way to find senders or receivers in the network. 2 MAC address helps you to prevent unwanted network access. 3 MAC address is a unique number; hence it can be used to track the device. 4 Wi-Fi networks at the airport use the MAC address of a specific device to identify it.
