The network administrator has been asked to give reasons for moving from IPv4 to IPv6. What are two valid reasons for adopting IPv6 over IPv4? (Choose two.)

IPv4 and IPv6 are the two primary versions of the Internet Protocol (IP). IPv4 is the older version that has been in use for several decades, while IPv6 is the newer version that is slowly replacing IPv4 due to its advantages. Two valid reasons for adopting IPv6 over IPv4 are:
Larger address space: IPv4 uses 32-bit addresses and can only support about 4.3 billion unique IP addresses, which are rapidly depleting due to the growth of the internet and the increasing number of connected devices. In contrast, IPv6 uses 128-bit addresses, providing over 340 undecillion unique IP addresses, which is more than enough to meet the growing demand for IP addresses. With IPv6, each device can have its unique IP address, and network administrators can simplify their network management tasks.
Autoconfiguration: IPv6 supports autoconfiguration, which simplifies the process of assigning IP addresses to devices on a network. In IPv4, network administrators need to manually assign IP addresses, configure DHCP servers, or use other methods to allocate IP addresses. In contrast, IPv6 devices can automatically configure their IP addresses using their link-local address and unique interface identifier, simplifying the process and reducing the risk of configuration errors.
Therefore, the two valid reasons for moving from IPv4 to IPv6 are the larger address space and autoconfiguration support. Other benefits of IPv6 include better security, improved routing efficiency, and support for new applications and services.
