Syntax

VARCHAR INET6_ATON(VARCHAR ipv6_string)

The reverse function of IPv6NumToString, it takes an IP address String and returns an IPv6 address in binary format. If the input string contains a valid IPv4 address, returns its IPv6 equivalent.

notice

It is the alias of ipv6_string_to_num_or_null. It will return NULL if the input string is not a valid IP address or NULL, which is the same with MySQL
