Module tp.netlib.discover.pyZeroconf.Zeroconf

Multicast DNS Service Discovery for Python, v0.12
Copyright (C) 2003, Paul Scott-Murphy

This module provides a framework for the use of DNS Service Discovery
using IP multicast.  It has been tested against the JRendezvous
implementation from <a href="http://strangeberry.com">StrangeBerry</a>,
and against the mDNSResponder from Mac OS X 10.3.8.

Classes
ServiceBrowser Used to browse for a service of a specific type.
ServiceInfo Service information...
Zeroconf Implementation of Zeroconf Multicast DNS Service Discovery Supports registration, unregistration, queries and browsing.
DNSAddress A DNS address record...
DNSCache A cache of DNS entries...
DNSEntry A DNS entry...
DNSHinfo A DNS host information record...
DNSIncoming Object representation of an incoming DNS packet...
DNSOutgoing Object representation of an outgoing packet...
DNSPointer A DNS pointer record...
DNSQuestion A DNS question entry...
DNSRecord A DNS record - like a DNS entry, but has a TTL...
DNSService A DNS service record...
DNSText A DNS text record...
Engine An engine wraps read access to sockets, allowing objects that need to receive data from sockets to be called back when the sockets are ready.
Listener A Listener is used by this module to listen on the multicast group to which DNS messages are sent, allowing the implementation to cache information as it arrives.
Reaper A Reaper is used by this module to remove cache entries that have expired.
