Understanding IP and MAC Addressing

What is the purpose of a MAC address?

• To identify a device globally on the internet

• To route frames on a local area network

• To provide a physical address for the router

• To encrypt data sent over the network

Which of the following is a characteristic of MAC addresses?

• Globally unique and routable on the internet

• Unique to each network interface card

• Used to route packets on the internet

• Consists of eight groups separated by colons

How many bits are in an IPv4 address?

• 256 bits

• 64 bits

• 32 bits

• 128 bits

What distinguishes IPv4 addresses from IPv6 addresses in terms of structure?

• IPv4 addresses are longer

• IPv4 uses hexadecimal, while IPv6 uses binary

• IPv4 addresses are assigned randomly

• IPv6 addresses use colons for separation, while IPv4 uses periods

Why are some IPv4 addresses reserved for special uses?

• All of the above

• For multicast

• For private networks

• For future expansion

What is the main reason for the transition from IPv4 to IPv6?

• IPv4 is not compatible with modern devices

• IPv6 provides better security features

• IPv4 addresses have been exhausted

• IPv6 is faster than IPv4

How does the division of an IP address identify a network and a host?

• The first part identifies the network, and the second part identifies the host

• The division is random and does not signify anything

• The first part identifies the host, and the second part identifies the network

• The entire address identifies the network only

How are IPv6 addresses represented?

• As four groups of four decimal numbers

• As eight groups of four hexadecimal digits

• As two groups of six hexadecimal digits

• As sixteen groups of two binary digits

What is the size of an IPv6 address?

• 32 bits

• 64 bits

• 128 bits

• 256 bits

What is the estimated number of IPv6 addresses?

• Exactly 1 trillion

• Unlimited

• About 340 undecillion

• About 4 billion
