Part of twisted.names.hosts View Source View In Hierarchy

A resolver that services hosts(5) format files.
Method __init__ Undocumented
Method lookupAddress Read any IPv4 addresses from self.file and return them as Record_A instances.
Method lookupIPV6Address Read any IPv6 addresses from self.file and return them as Record_AAAA instances.
Method _aRecords Return a tuple of dns.RRHeader instances for all of the IPv4 addresses in the hosts file.
Method _aaaaRecords Return a tuple of dns.RRHeader instances for all of the IPv6 addresses in the hosts file.
Method _respond Generate a response for the given name containing the given result records, or a failure if there are no result records.

Inherited from ResolverBase:

Method exceptionForCode Convert a response code (one of the possible values of dns.Message.rCode to an exception instance representing it.
