What is the difference between IP address and MAC address and how they are used?
A MAC address is given to a network adapter when it is manufactured. It is hardwired or hard-coded onto your computer’s network interface card (NIC) and is unique to it. Something called the ARP (Address Resolution Protocol) translates anIP address into a MAC address.

What is Mac address?
A media access control address (MAC address) of a computer is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi.
A Mac address is Hardware address. Where IP addresses are associated with TCP/IP (networking software), MAC addresses are linked to the hardware of network adapters. MAC addresses are useful for network diagnosis because they never change, as opposed to a dynamic IP address, which can change from time to time. For a network administrator, that makes a MAC address a more reliable way to identify senders and receivers of data on the network.
what is mac address spoofing?
MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. 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.
what is mac address filtering?
MAC address filtering allows you to define a list of devices and only allow those devices on your Wi-Fi network. That’s the theory, anyway. In practice, this protection is tedious to set up and easy to breach. This is one of the Wi-Fi router features that will give you a false sense of security
what is mac address used for?
MAC addresses are used to send Ethernet frames between two stations in the same local area network. Each station has a unique MAC address that is used to identify who is the sender (source address) and who is the receiver (destination address). But Ethernet frames can’t travel between networks.
Are all MAC addresses unique?
All a MAC address does is identify a particular network device, in the case of an ISP, your modem. They are unique because if you had two NICs in the same network with the same MAC address it you would have severe problems. People have enough problems with duplicate IP addresses on a network.
ip Address Information All Access:
What is my ip address?
ip address is an (internet protocol address) identifier assigned to each computer and other device (e.g., printer, router, mobile device, etc.) connected to a TCP/IP network that is used to location and identify the node in communications with other nodes on the network.
An IP address (short for Internet Protocol address) is used to identify computers on the Internet. It works like a return address would on a piece of mail.
Why does the IP address change?
Make a note of the IP address—but don’t get too attached because most likely, your ISP is called a dynamic IP address, which means it’s subject to change on you. (Not that it will, but it can.) If it weren’t a dynamic IP address, it would be referred to as a static IP address…unchanging.
What is a static IP address?
DNS maps domain names to IP addresses. … Your browser then connects to that IP address. Difference between static and dynamic IPs. When a device is assigned a static IP address, the address does not change. Most devices use dynamic IP addresses, which are assigned by the network when they connect and change over time.
What is the IP range?
An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing.
How IP addresses work
When your computer or device sends a request, like a search on Google, it tags the request with your IP address. That way Google knows where to send the response. Your IP address is usually based on a real-world location, so Google might use your IP address to guess where you are and give you local results.
