However, some internet users may encounter issues with their ISPs when they change equipment, such as upgrading their router or obtaining a new residential gateway.
This is simply a number that identifies the network device that you are using, and there shouldn’t be any reason to change it. In general, you will not find any cause for changing your MAC address. Will I Ever Need to Change My MAC Address? In short, every device will in some way have a completely unique MAC address, whether they were made by the same manufacturer or not. However, as already explained, each manufacturer has its own prefix, so this number will vary. You may also find that the identifier is the same between two products from different manufacturers. However, if the prefix is different, the product identifier may be the same, even when the products are from the same manufacturer. All products from the same manufacturer that have the same prefix (or first set of digits) will have a distinct second set of numbers.

The next set of numbers, which makes up the remaining 24 bits, is essentially a serial number.
This is because some of the biggest manufacturers utilize multiple prefixes across their lines of products. It’s not unusual to find that several devices created by the same manufacturer have different prefixes, however. The first six digits, which makes up 24 bits in a 48-bit network, is a prefix that is used to identify the manufacturer of the device. The answer is simpler than you may think. You may be wondering what these numbers mean. Two additional formats for 48-bit addresses are MM-MM-MM-SS-SS-SS or .Ī 48-bit address that is converted to a 64-bit address would be formatted as MM:MM:MM:FF:FE:SS:SS:SS. Traditionally, these addresses are written in the format of MM:MM:MM:SS:SS:SS. What Are Typical Formats for MAC Addresses?Īs mentioned, there are a few different formats that are used for MAC addresses, depending upon the network and specific hardware. These identifiers are used to differentiate between 48-bit addresses and 64-bit addresses. These networks translate 48-bit networks to 64-bit networks by inserting an FFFE value in the middle. When using an IPv6 network, the settings change a bit more. Certain wireless home automation systems, for example, may require a 64-bit MAC address. However, some types of hardware require a 64-bit MAC address. Traditionally, MAC addresses are made up of 12-digit numbers and are made up of 48 bits, or 8 bytes. However, they all follow the same set of rules when it comes to format. Like IP addresses, MAC addresses are all unique. Your MAC address can be access through your operating system by using commands.

Wi-Fi and Bluetooth are among the technologies that also use MAC addresses. While it was once known as an Ethernet address, other types of hardware have been introduced making this term more obsolete. It is also known as a fixed address for this reason.
This number is set by the manufacturer and is embedded within the hardware so it cannot be altered. It is a set of numbers that identifies network devices. However, there are some very distinct differences. Just like an IP address identifies your connected device and allows it to communicate with other devices while connected to the internet, the MAC address is similar in that it is used as an identifier. While many people are familiar with IP addresses – or rather, the unique address that identifies online devices including computers, laptops, and tablets – you may or may not be familiar with a MAC address, what it is, how it works, and the specifics of this identifier. As one would expect, the internet and the hardware used to get online all have settings and have “addresses” that are used to communicate with each other, much like homes have their own addresses used to identify them. The fact that we can share data with others, access online content from anywhere in the world, and do all of it wirelessly shows us just how amazing technology can be. The internet is really a brilliant and innovative thing when you think about it.
