IP

    Internet protocol (IP) support functions such as DNS resolution.

    IP contains support functions for the Internet Protocol (IP). TCP/IP support is in different classes (see and TCP_Server). IP provides DNS hostname resolution support, both blocking and threaded.

    enum ResolverStatus:

    • RESOLVER_STATUS_NONE = 0 —- DNS hostname resolver status: No status.
    • RESOLVER_STATUS_WAITING = 1 —- DNS hostname resolver status: Waiting.
    • RESOLVER_STATUS_ERROR = 3 —- DNS hostname resolver status: Error.
    • TYPE_NONE = 0 —- Address type: None.
    • TYPE_IPV4 = 1 —- Address type: Internet protocol version 4 (IPv4).
    • TYPE_IPV6 = 2 —- Address type: Internet protocol version 6 (IPv6).
    • TYPE_ANY = 3 —- Address type: Any.
    • RESOLVER_MAX_QUERIES = 32 —- Maximum number of concurrent DNS resolver queries allowed, is returned if exceeded.
    • RESOLVER_INVALID_ID = -1 —- Invalid ID constant. Returned if RESOLVER_MAX_QUERIES is exceeded.

    Removes all of a ‘s cached references. If no hostname is given, all cached IP addresses are removed.

    • void erase_resolve_item ( id )

    Removes a given item from the queue. This should be used to free a queue after it has completed to enable more queries to happen.

    • Array get_local_addresses ( ) const

    Returns all of the user’s current IPv4 and IPv6 addresses as an array.

    • get_local_interfaces ( ) const

    Each adapter is a dictionary of the form:

    • String get_resolve_item_address ( id ) const

    Returns a queued hostname’s IP address, given its queue id. Returns an empty string on error or if resolution hasn’t happened yet (see get_resolve_item_status).

    • get_resolve_item_status ( int id ) const

    Returns a queued hostname’s status as a constant, given its queue .

    • resolve_hostname_queue_item ( String host, ip_type=3 )

    Creates a queue item to resolve a hostname to an IPv4 or IPv6 address depending on the Type constant given as . Returns the queue ID if successful, or on error.
