toIPv6 Function Enhancements for Parsing IPv4 Addresses

Why it matters

This feature addresses the need for converting IPv4 addresses into their corresponding IPv6 representation, simplifying handling of IP addresses in mixed network environments and enhancing query flexibility.

How to use it

To use this feature, simply call the toIPv6 function with an IPv4 address string as the argument, for example:

SELECT toIPv6('192.168.1.1')

This will return the IPv6-mapped equivalent of the given IPv4 address.
