IGCSE 3.4 Internet Protocol(IP) Address

What is the purpose of a MAC address?

• To identify a host computer on the internet

• To control internet traffic

• To assign IP addresses to devices

• To route frames on a local area network

Traditional MAC addresses are represented by (a)   .

• 16-digit octal numbers
• 6-digit binary numbers
• 12-digit hex numbers
• 8-digit decimal numbers

Match the following statements with their correct descriptions.

• Frames are used for static IP addresses, packets for dynamic IP addresses

• Frames are used for wired connections, packets for wireless connections

• Frames are used for wired connections, packets for wireless connections

• Frames are used for IPv4, packets for IPv6

• Frames are used for IPv4, packets for IPv6

• Frames are used for static IP addresses, packets for dynamic IP addresses

• Frames are used on local area networks, packets on wide area networks

• Frames are used on local area networks, packets on wide area networks

Match the following IP address components.

• Host Component

• By separating the odd and even numbers

• Host Component

• By splitting the address into two parts

• Network Component

• By converting the address to binary

• Network Component

• By using different protocols

What is the size of an IPv4 address in bits?

• 128 bits

• 16 bits

• 32 bits

• 64 bits

There are (a)   possible IPv4 addresses.

• 2 billion
• 16 billion
• 4 billion
• 8 billion

Why was IPv6 introduced?

• To reduce the number of available addresses

• To increase the speed of internet connections

• To overcome the limitation of IPv4 addresses

• To simplify network configurations

IPv6 addresses are represented by (a)   groups of four hexadecimal digits

• Six pairs separated by colons
• Ten groups of three binary digits
• Four numbers separated by periods
• Eight groups of four hexadecimal di

What is the approximate number of IPv6 addresses available?

(a)  

• 340 trillion trillion trillion
• 400 trillion
• 40 trillion
• 4 trillion

What is the main advantage of IPv6 over IPv4?

• Better compatibility with older devices

• Increased number of available addresses

• More secure encryption

• Faster data transfer speeds
