World of Computer Networking Your CCNA start - Internet Protocol Version 4 (IPv4) Address Format

The video tutorial explains the differences between IP version 4 and IP version 6 addresses, focusing on the format and limitations of IPv4. It describes how IPv4 addresses are structured using four octets, each 8 bits long, resulting in a 32-bit address. The tutorial highlights the limited number of IPv4 addresses available and discusses techniques like private and public IP address spaces and Network Address Translation (NAT) to manage these limitations. It also compares IP addresses with MAC addresses, noting the larger address space of MAC addresses.

What is the total length of an IP version 4 address in bits?

• 128 bits

• 32 bits

• 16 bits

• 64 bits

What is the range of decimal values each octet in an IP version 4 address can have?

• 0 to 100

• 0 to 128

• 0 to 255

• 0 to 512

Why is the total number of IP version 4 addresses considered insufficient?

• Because it is not compatible with IP version 6

• Because it is less than 1 billion

• Because it is more than the number of MAC addresses

• Because it cannot provide unique addresses for all devices worldwide

How many bits does a MAC address have compared to an IP version 4 address?

• 32 bits

• 48 bits

• 64 bits

• 128 bits

Which technique is used to manage the limited IP version 4 address space?

• Network Address Translation (NAT)

• Dynamic Host Configuration Protocol (DHCP)

• Subnetting

• Domain Name System (DNS)
