//MAC address vs IP address
A MAC address identifies the physical device and is set by the manufacturer — it does not change. An IP address identifies the device on a network and CAN change, for example when you connect somewhere else. Think of the MAC as the serial number and the IP as the postal address.
MAC: 00-1A-2B-3C-4D-5E (hex, 48 bits, fixed)
IPv4: 192.168.1.10 (denary, 32 bits)
IPv6: 2001:0db8:85a3::8a2e (hex, 128 bits)//Why IPv6 exists
IPv4 has 32 bits, giving about 4 billion addresses — and the world ran out. IPv6 uses 128 bits, which is effectively unlimited, and is written in hexadecimal with colons.
//Router
A router connects networks together and directs packets towards their destination, using the IP address in the packet header to choose the route.
CHECK YOURSELF
1.Which address is fixed by the manufacturer and does not change?
2.Why was IPv6 introduced?
3.What does a router do?
