parse_ipv6_mask( Expression, PrefixMask )

Arguments

Expression: String expression representing IPv6 that will be converted to long.
PrefixMask: An integer from 0 to 128 representing the number of most-significant bits that are taken into account.

If the conversion is successful, returns a string representing a canonical IPv4 or IPv6 network address.

If the conversion fails, returns null.

Examples
