getHostByName(self,
name,
timeout=10)
Resolve the domain name C{name} into an IP address.
@type name: C{str}
@type timeout: C{int}
@rtype: C{Deferred}
@return: The callback of the C{Deferred} that is returned will be
passed a string that represents the IP address of the specified
name, or the errback will be called if the lookup times out. If
multiple types of address records are associated with the name,
A6 records will be returned in preference to AAAA records, which
will be returned in preference to A records. If there are multiple
records of the type to be returned, one will be selected at random.
@raise L{TimeoutError<twisted.internet.defer.TimeoutError>}: Raised
(asynchronously) if the name cannot be resolved within the
specified timeout period.
