Use of IP and MAC addressing - Coggle Diagram
Use of IP and MAC addressing
MAC - Media Access Control , which is used to route frames on a local area network (LAN)
If the LAN is connected to a WAN such as the internet, a different addressing method is required
IPv4
32 bits in size
A router has a unique WAN-facing IP address and a LAN-facing IP address - this enables a LAN device to have the same IP address as another device on a separate LAN
Four numbers between 0 and 255 separated with periods (e.g 69.89.31.212)
IPv4 is being replaced by IPv6 because unique statistic static addresses are running out
First 3 bytes of the IPv4 is the network identifier , and the last byte is the host identifier
107.56.94
.111
.111 - host identifier
107.56.94 - network identifier
Uses binary
IP addressing - Internet protocol, which is used to route frames on a wide area network (WAN). We refer to frames as packets
The internet of things
Any device that has a NIC that can connect to a network , especially the internet , is given an IP address.
This is the main reason for running our of IPv4 addresses
IPv6
128 bits in size
Eight groups of four 16-bit hex values separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334)
Uses Hexadecimal
