    Check if a given string is a valid IP address of a given type.

        value (str): The string to check.
        check_type (typing.Literal[...]):
            The type of IP address to check for. The following values are valid:

            - "ipv4": A valid IPv4 address.
            - "ipv4network": A valid IPv4 network address.
            - "ipv4interface": A valid IPv4 interface address.
            - "ipv6": A valid IPv6 address.
            - "ipv6network": A valid IPv6 network address.
