IP and MAC Addressing

What is the difference between IPv4 and IPv6 addressing?

• IPv4 uses 128-bit addresses, IPv6 uses 32-bit addresses

• IPv4 uses 32-bit addresses, IPv6 uses 128-bit addresses

• IPv4 uses 32-bit addresses, IPv6 uses 64-bit addresses

• IPv4 uses 64-bit addresses, IPv6 uses 128-bit addresses

Explain the structure of a MAC address.

• A MAC address is a 48-bit unique identifier assigned to network interfaces, with the first 24 bits representing the manufacturer's unique identifier and the last 24 bits uniquely identifying the network interface.

• MAC addresses are randomly generated by devices

• A MAC address is a 32-bit identifier used for network routing

• The structure of a MAC address includes the IP address of the device

What is the purpose of the ARP protocol?

• To map IP addresses to MAC addresses on a local network.

• To encrypt data packets on a network

• To establish secure VPN connections

• To manage domain name resolution

How does subnetting help in IP addressing?

• Subnetting is not relevant for IP addressing

• Subnetting increases the complexity of IP addressing

• Subnetting helps in organizing and managing IP addresses by dividing a larger network into smaller subnetworks.

• Subnetting reduces the security of IP addresses

What is CIDR notation and how is it used in networking?

• CIDR notation is used in networking to encrypt data packets for secure transmission.

• CIDR notation is used in networking to represent IP addresses and their associated network prefixes in a concise and efficient manner.

• CIDR notation is used in networking to represent domain names instead of IP addresses.

• CIDR notation is used in networking to determine the physical location of devices on a network.

How many bits are used in an IPv4 address?

• 16 bits

• 64 bits

• 8 bits

• 32 bits

What is the full form of ARP?

• ARP

• ARF

• ARL

• ARQ

What is the significance of the last 64 bits in an IPv6 address?

• Network identifier

• Subnet mask

• Host identifier

• Interface identifier

Explain the concept of network masks in subnetting.

• Network masks are represented in decimal format (e.g., 255.255.255.0 for a Class C network) and are used in conjunction with IP addresses to determine the network ID and host ID.

• Network masks are always written in binary format

• Network masks are used to hide the IP address of the sender in a network

• Network masks are only used in IPv6 addressing

How does a device determine if an IP address is on the same subnet?

• By checking the DNS server

• By pinging the IP address

• By comparing the network portion of the IP address with the subnet mask

• By comparing the IP address with the MAC address
