Why are MAC addresses expressed in hex?
An Ethernet MAC address consists of a 48-bit binary value. Hexadecimal is used to identify an Ethernet address because a single hexadecimal digit represents 4 binary bits. Therefore, a 48-bit Ethernet MAC address can be expressed using only 12 hexadecimal values.
Is MAC Address binary or hexadecimal?
MAC addresses are binary numbers which are represented in its hexadecimal equivalent. For example, the 48-bit MAC address 10101010.11110000.
Are MAC addresses in hex?
As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.
What are the reasons why the IP address is separated by the dotted decimal numbers?
Most commonly, they are expressed by dividing the 32 bits into four bytes and converting each to decimal, then separating these numbers with dots to create dotted decimal notation. Dotted decimal notation provides a convenient way to work with IP addresses when communicating amongst humans.
How do you change MAC address to decimal?
A mac address has a size of 6 byte. This bytes are seperated by colons. To convert the mac address to decimal you have to convert these single bytes. So hex AA would be 140 decimal, BB=187 and CC=204 and so on…
Why do we consider dividing an IP address into network address and host address?
Division of IP space into classes is a concept that defines what part of IP belongs to a network and what part belongs to the host. Class A (subnet of 255.0. 0.0) has first octet that belongs to the network and the rest to the host. It can support 255^3 number of hosts.
What is the purpose of dotted decimal representation?
Dotted decimal notation effectively puts numbers in different containers that are separated by dots or decimals. The dotted decimal notation system used so commonly in IP addressing is just one of several choices for representing numbers differently.
What is physical MAC address?
The MAC address (short for media access control address) is the worldwide unique hardware address of a single network adapter. The physical address is used to identify a device in computer networks. With Microsoft Windows, the MAC address is referred to as the physical address.
