Known implementations: twisted.internet._resolver.GAIResolver, twisted.internet._resolver.SimpleResolverComplexifier, twisted.internet.endpoints._SimpleHostnameResolver

View In Hierarchy

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.
def resolveHostName(resolutionReceiver, hostName, portNumber, addressTypes, transportSemantics): (source)
Initiate a hostname resolution.
resolutionReceiver:IResolutionReceiveran object that will receive each resolved address as it arrives.
hostName:strThe name of the host to resolve. If this contains non-ASCII code points, they will be converted to IDNA first.
portNumber:intThe port number that the returned addresses should include.
addressTypes:Sequence[IAddress]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.
transportSemantics:strA 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.
IResolutionReceiverThe resolution in progress.
