Answer Key

Differences between a MAC address and an IP address
Section A: Quick Questions
Q1
A — The manufacturer, when the device is made
Q2
A — IP address
Q3
A — MAC address
Q4
B — MAC address
Q5
B — IPv4 address
Section B: Match the Pairs
Q1
A4:5E:60:C2:1B:9F → A MAC address: written in hexadecimal and set by the manufacturer, so it stays the same
Q2
192.168.1.25 → An IPv4 address: four denary numbers given by the network, so it can change
Q3
The manufacturer sets the MAC address, but the network gives the device its IP address → MAC: set by manufacturer / IP: given by network
Q4
A MAC address is permanent, but an IP address is changeable → MAC: permanent / IP: changeable
Q5
A laptop's MAC address changes when it joins a new Wi-Fi network → The MAC address is fixed by the manufacturer and stays the same on every network. It is the IP address that changes.
Q6
The network gives a device its MAC address → The manufacturer sets the MAC address when the device is made. The network gives the IP address.
Section C: Definitions
Q1
MAC address vs IP address — MAC is fixed by the manufacturer and stays the same, written in hex. IP is given by the network and can change, written in denary (IPv4) or hex (IPv6).
Section D: Fill in the Blanks
Q1
MAC address: set by the manufacturer
Q2
IP address: given by the network
Q3
MAC address: permanent IP address: changeable
Q4
MAC example: 3C:5A:B4:1F:2E:90 (hex)
Q5
IPv4 example: 192.168.1.10 (denary)
Section E: Spot the Error
Q1
C — A MAC address is set by the manufacturer when the device is made, not by the network. The line should be 'MAC set by manufacturer'.
Q2
B — An IP address is given to the device by the network (for example by the router). The manufacturer sets the MAC address, not the IP address.
Q3
B — A MAC address is written in hexadecimal (digits 0-9 and letters A-F), not in denary only.
Q4
A — An IPv4 address is written in denary, as four numbers from 0 to 255. Only IPv6 addresses are written in hexadecimal.
Q5
C — A MAC address is permanent and does not change when the device joins a different network. It should read 'MAC stays the same'.
