Question

What are four problems with IPv4 addressing workarounds? (Choose four.)

A) Limited address space

B) Complexity of subnetting

C) Incompatibility with legacy devices

D) Difficulty in managing NAT configurations

E) Lack of support for CIDR

F) Security vulnerabilities with NAT implementations

Answer 1

IPv4 addressing has issues including limited address space, complexity of subnetting, incompatibility with legacy devices, and difficulty in managing NAT configurations.

Step-by-step explanation:

IPv4 addressing has several problems that require workarounds:

1. Limited address space: IPv4 addresses are 32 bits long, providing a maximum of 4.3 billion unique addresses. With the growing number of devices connected to the internet, this address space is quickly depleting.
2. Complexity of subnetting: Subnetting is a technique used to divide a single IP network into multiple subnetworks. The process can be complex and requires careful planning and configuration.
3. Incompatibility with legacy devices: Older devices may not support newer address assignment methods, making it challenging to integrate them into IPv4 networks.
4. Difficulty in managing NAT configurations: Network Address Translation (NAT) is commonly used to extend the limited address space of IPv4. However, managing and configuring NAT can be complex, leading to potential misconfigurations and network issues.
