IP and MAC addresses

Identify an example of an IPv4 address

• FE80:CD00:0000:0CDE:1257:0000:211E:729C

• 192.168.0.1

Identify an example of a MAC address

• 1A:BC:22:31:AA:99

• 192.168.0.1

Where are IP addresses assigned to?

• Any computer connected to a router, the router itself, hub/switch, server, websites

• NIC, switch and router

Where are MAC addresses assigned to?

• Any computer connected to a router, the router itself, hub/switch and server.

Static IP addresses tend to be assigned to which device(s)?

• NIC, Router

• Desktop, laptop, smartphone, website

• Server

Dynamic IP addresses tend to be assigned to which device(s)?

How many bytes and bits is IPv4?

• 16 bytes = 128 bits

  (16 x 8)

• 4 bytes = 32 bits

  (4 x 8)

How many bytes and bits is IPv6?

• 16 bytes = 128 bits

  (16 x 8)

• 4 bytes = 32 bits

  (4 x 8)

Choose two differences between an IP and MAC address

• IP addresses consist of numbers (decimal). Whereas MAC addresses use letters and numbers (hex)

• Ip addresses are always dynamic, whereas MAC addresses are static.

• IP addresses can be static and dynamic, whereas MAC addresses are static.

• IP address tend to be 9 bytes long, whereas MAC addresses are 6 bytes long.

Why was IPv6 developed?

• With IPv4 there was beginning to be a shortage of IP addresses.

• As a new and improved protocol.
