A) Larger address space

B) Improved security features

C) Simplified header structure

D) Enhanced support for mobile devices

E) Improved routing efficiency with CIDR

F) Compatibility with older network equipment

Answer 1

IPv6 benefits over IPv4 include a larger address space, improved security features, a simplified header structure, and enhanced support for mobile devices, which collectively solve many issues that arose with the older IPv4 protocol.

Step-by-step explanation:

There are several benefits of IPv6 over IPv4, four of which are particularly noteworthy:

• Larger address space: IPv6 provides a much larger address space than IPv4, using 128-bit addresses compared to IPv4's 32-bit addresses. This expansion substantially increases the number of available IP addresses, accommodating the growth of the internet and the proliferation of connected devices.
• Improved security features: IPv6 was designed with security in mind, including mandatory support for IPsec (IP Security), which provides confidentiality, authentication, and data integrity.
• Simplified header structure: The header of an IPv6 packet is simpler than that of IPv4, which can improve processing speed and efficiency.
• Enhanced support for mobile devices: IPv6 supports mobile IP natively, allowing mobile devices to switch between different networks seamlessly without losing their IP address.

These features represent significant advancements over IPv4, addressing the limitations and challenges of the older protocol.
