Known implementations: twisted.internet._resolver.GAIResolver, twisted.internet._resolver.SimpleResolverComplexifier, twisted.internet.endpoints._SimpleHostnameResolver
An IHostnameResolver
can resolve a host name and port number into a series of IAddress
objects.
| Present Since | Twisted 17.1.0 | |
| Method | resolveHostName | Initiate a hostname resolution. |
Initiate a hostname resolution.
| Parameters | resolutionReceiver | an object that will receive each resolved address as it arrives. (type: IResolutionReceiver) |
| hostName | The name of the host to resolve. If this contains non-ASCII code points,
they will be converted to IDNA first. (type: unicode) | |
| portNumber | The port number that the returned addresses should include. (type: int
greater than or equal to 0 and less than 65536) | |
| addressTypes | An iterable of implementors of IAddress
that are acceptable values for resolutionReceiver to receive
to its addressResolved.
In practice, this means an iterable containing twisted.internet.address.IPv4Address,
twisted.internet.address.IPv6Address,
both, or neither. (type: collections.abc.Iterable
of type) | |
| transportSemantics | A string describing the semantics of the transport; either
'TCP' for stream-oriented transports or 'UDP' for
datagram-oriented; see twisted.internet.address.IPv6Address.type
and twisted.internet.address.IPv4Address.type. (type: native str) | |
| Returns | The resolution in progress. (type: IResolutionReceiver) | |
