# parseIPv4Address method Null safety

List<int> parseIPv4Address (

1. String host

)

Parse the `host` as an IP version 4 (IPv4) address, returning the address as a list of 4 bytes in network byte order (big endian).

Throws a FormatException if `host` is not a valid IPv4 address representation.

## Implementation

    static List<int> parseIPv4Address(String host) =>
        _parseIPv4Address(host, 0, host.length);
