Question

What factors limit the number of available ipv4 addresses? (select all that apply)

A) Limited Address Length
B) Increased Internet Usage
C) Adoption of IPv6
D) Technological Advancements

Answer 1

The primary factors limiting the number of available IPv4 addresses are the limited 32-bit length of IPv4 addresses and the dramatic increase in internet usage. Technological advancements have contributed to the increased demand, while the adoption of IPv6 does not limit IPv4 availability but rather provides a solution to the shortage.

Step-by-step explanation:

The factors that limit the number of available IPv4 addresses include:

• Limited Address Length: IPv4 addresses are 32 bits long, allowing for approximately 4.3 billion unique addresses. This seemed sufficient in the early days of the internet but is not enough for the current demand.
• Increased Internet Usage: With more devices than ever connecting to the internet, including smartphones, tablets, and Internet of Things (IoT) devices, the demand for IP addresses has skyrocketed.
• Technological Advancements: Although technological advancements have exponentially increased the number of devices that need IP addresses, it's not a direct factor that limits IPv4 addresses. It's rather a reason for the increased consumption of the limited addresses.

Factors C) Adoption of IPv6 and D) Technological Advancements relate to the transition and development surrounding IP addressing but do not directly limit the number of available IPv4 addresses.
