ipv6_is_match
The ipv6_is_match
function matches two IPv6 or IPv4 network address strings. The two IPv6/IPv4 strings are parsed and compared while accounting for the combined IP-prefix mask calculated from argument prefixes, and the optional PrefixMask argument.
Syntax
ipv6_is_match( Expr1, Expr2 [, PrefixMask ] )
Arguments
- Expr1, Expr2: A string expression representing an IPv6 or IPv4 address. Denote a subnet mask with a forward slash
/
. - PrefixMask: An integer from 0 to 128 representing the number of most-significant bits that are taken into account.
Results
true
: If the long representation of the first IPv6/IPv4 string argument is equal to the second IPv6/IPv4 string argument.false
: Otherwise.null
: If conversion for one of the two IP strings wasn’t successful.
