![]() ![]() You should know a thing or two about decimal numbers before delving into this tutorial. Conversion Calculators - Here you'll find a simple, automatic calculator to switch between hex, binary, and decimal.Converting To/From Binary - This page shows how you can convert between binary and hex.Converting To/From Decimal - This page covers our preferred methods of converting between hex and decimal.This page covers the 16 digits of hex, how we represent hex numbers, and how to count in hex. This tutorial covers everything hex-related that you might encounter in electronics or programming. It's important to understand how hex works, because, in many cases, it makes more sense to represent a number in base 16 than with binary or decimal. Hex, along with decimal and binary, is one of the most commonly encountered numeral systems in the world of electronics and programming. The base 2, binary, system uses just two digit values (0 and 1) to represent numbers. Binary (base 2) is also popular in the engineering world, because it's the language of computers. There are many (infinite!) other numeral systems out there. Hex uses the standard 0-9, but it also incorporates six digits you wouldn't usually expect to see creating numbers: A, B, C, D, E, and F. It just so happens that hex uses a set of 16 unique digits. Hex, like decimal, combines a set of digits to create large numbers. Decimal is a base 10 number system (perfect for beings with 10 fingers), and it uses a collection of 10 unique digits, which can be combined to positionally represent numbers. In that way it's no different than the most famous of numeral systems (the one we use every day): decimal. Hexadecimal - also known as hex or base 16 - is a system we can use to write and share numerical values. MAC Addresses of the range 33:33:xx:xx:xx:xx are reserved for IPv6 Multicast.Once you understand hex, the next step is decoding the matrix!.An Ethernet Switch will flood an Ethernet Frame with FF:FF:FF:FF:FF:FF as the destination MAC Address to all its connected ports. ![]() MAC Address FF:FF:FF:FF:FF:FF is reserved for Broadcast type of communication.Decimalįollowing are some important MAC addresses you need to remember. Refer the following table for easy conversion from binary to decimal and hexadecimal numbers. You can search for the OUI listings in following URLs. Refer below image to understand OUI (Organizationally Unique Identifier) part and NIC specific part of MAC addresses. Network Interface Controller specific number are assigned by manufacturer to the NIC. Next three bytes are Network Interface Controller Specific number. OUI (Organizationally Unique Identifier) numbers are assigned by the IEEE to te manufacturer. The first three bytes of the MAC address identifies the vendor who manufactured the product (Example: a NIC Card), and is known as OUI (Organizationally Unique Identifier). Type the command "ipconfig /all" in the prompt and Enter. ![]() To view the MAC Address of your network card when you are using Windows Operating System, run command prompt, cmd (Right-click Start > Run > type cmd and click "OK"). The first nibble 1010 from the left most byte in above example represent the first equivalent hexadecimal A in its hexadecimal representation, and the second nibble 1010 from the left most byte in above example represent the second equivalent hexadecimal A in its hexadecimal representation. In a MAC address, one hexadecimal digit resembles a group of four contiguous binary bits, called a nibble. MAC addresses are binary numbers which are represented in its hexadecimal equivalent. The scope of a MAC address is limited within a Local Area Network (LAN). MAC addresses are typically locally specific. MAC (Media Access Control) addresses are hard-coded into network adapter. MAC addresses are theoretically permanent numbers, which are burned into the network card.Įvery network adapter has a MAC (Media Access Control) address assigned to it when it is manufactured. The purpose of representing the binary address in hexadecimal format is to make it easier for humans to read and understand. Media Access Control (MAC address or Layer 2 addresses or physical address or hardware address) addresses are 48 bit (six bytes) binary addresses represented in hexadecimals. ![]()
