Convert ip to mac address online5/2/2024 ![]() So, every device has an IP address that starts with those three octets and ends with a unique number. It's the default subnet on most residential routers. If yours is like most homes in the world, you have a subnet that starts with 192.168.1. You've got an Xbox, iPhone, and a couple of computers. The router connects all your devices to the internet. How MAC Addresses, IP Addresses, and Subnet Masks Work Together These parts are defined by the subnet mask assigned to the address.Ī common subnet mask of 255.255.255.0 tells us the first three octets of the address denote the network portion, and the last octet denotes the address's host portion. Every IPv4 address has a network portion and a host portion. ![]() Subnet masks work like a filter to help determine which part of an IP address identifies the network and which identifies the device on that network. Think of it like a street address you might give out to receive mail where you live - except the IP address can change over time. Some websites always have the same IP address, called a Static IP Address. Years ago, you kept the same IP address on your computer, but now IP addresses are usually dynamically assigned. The IP address is a virtual address that changes depending on the network your device connects to, or even when you reboot your computer. (The 48-bit identifier has 281.5 trillion combinations, so you shouldn't worry about duplicates.) While most people don’t remember or care about MAC addresses, they work behind the scenes to identify your device on a network. Represented by a 12-digit hexadecimal number, every device worldwide has a unique MAC address. It's hard-coded to the network card from the manufacturer. What is a MAC Address?Ī MAC address is a device's "physical" address. How does it work? What do these different addresses mean? For instance, a MAC address, IP address, and subnet mask are responsible for making sure you land in the right spot. But most people don't realize a lot happens behind the scenes to get you there. It's a simple process most of us perform multiple times a day. A MAC address is hard coded into a device, while the IP address is the virtual address. Quick Definition: IP addresses and MAC addresses both identify devices on a network, but they work a bit differently.
