## IP address functions
-For the IPv4 address functions, the `address` argument can either be an IPv4 dotted-decimal string (e.g., "192.168.0.1") or an IP address represented as a long (e.g., 3232235521). The `subnet` argument should be a string formatted as an IPv4 address subnet in CIDR notation (e.g., "192.168.0.0/16").
+For the IPv4 address functions, the `address` argument accepts either an IPv4 dotted-decimal string (e.g., "192.168.0.1") or an IP address represented as a long (e.g., 3232235521). Format the `subnet` argument as an IPv4 address subnet in CIDR notation (e.g., "192.168.0.0/16").
| function | description |
| --- | --- |
| ipv4_match(address, subnet) | Returns 1 if the `address` belongs to the `subnet` literal, else 0. If `address` is not a valid IPv4 address, then 0 is returned. This function is more efficient if `address` is a long instead of a string.|
-| ipv4_parse(address) | Parses `address` into an IPv4 address stored as a long. If `address` is a long that is a valid IPv4 address, then it is passed through. Returns null if `address` cannot be represented as an IPv4 address. |
-| ipv4_stringify(address) | Converts `address` into an IPv4 address dotted-decimal string. If `address` is a string that is a valid IPv4 address, then it is passed through. Returns null if `address` cannot be represented as an IPv4 address.|
+| ipv4_parse(address) | Parses `address` into an IPv4 address stored as a long. Returns `address` if it is already a valid IPv4 integer address. Returns null if `address` cannot be represented as an IPv4 address. |
