String

get_resolve_item_address ( int id ) const

Array

get_resolve_item_addresses ( int id ) const

ResolverStatus

String

resolve_hostname ( String host, Type ip_type=3 )

PackedStringArray

resolve_hostname_addresses ( String host, Type ip_type=3 )

int

resolve_hostname_queue_item ( String host, Type ip_type=3 )


Enumerations

enum ResolverStatus:

ResolverStatus RESOLVER_STATUS_NONE = 0

DNS hostname resolver status: No status.

ResolverStatus RESOLVER_STATUS_WAITING = 1

DNS hostname resolver status: Waiting.

ResolverStatus RESOLVER_STATUS_DONE = 2

DNS hostname resolver status: Done.

ResolverStatus RESOLVER_STATUS_ERROR = 3

DNS hostname resolver status: Error.


enum Type:

Type TYPE_NONE = 0

Address type: None.

Type TYPE_IPV4 = 1

Address type: Internet protocol version 4 (IPv4).

Type TYPE_IPV6 = 2

Address type: Internet protocol version 6 (IPv6).

Type TYPE_ANY = 3

Address type: Any.


Constants

RESOLVER_MAX_QUERIES = 256

Maximum number of concurrent DNS resolver queries allowed, RESOLVER_INVALID_ID is returned if exceeded.

RESOLVER_INVALID_ID = -1

Invalid ID constant. Returned if RESOLVER_MAX_QUERIES is exceeded.


Method Descriptions

void clear_cache ( String hostname="" )

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


void erase_resolve_item ( int id )

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


PackedStringArray get_local_addresses ( ) const

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


Dictionary[] get_local_interfaces ( ) const

Returns all network adapters as an array.

Each adapter is a dictionary of the form:

{
    "index": "1", # Interface index.
    "name": "eth0", # Interface name.
    "friendly": "Ethernet One", # A friendly name (might be empty).
    "addresses": ["192.168.1.101"], # An array of IP addresses associated to this interface.
}

String get_resolve_item_address ( int id ) const

Returns a queued hostname's IP address, given its queue id</
