There should be NO need for this if you setup service discovery properly for the network. If done properly you go from IP address and netmask to a delegated forward domain which accepts update requests from the devices on the network. Unfortunately the Presto documentation sucks when it comes to explaining how to setup service discovery properly. They hard code "presto" in their examples rather than saying to use a forward zone you control.
See https://tools.ietf.org/html/rfc6763 for details of how it is designed to work. Section 11 shows how to go from IP address and netmask to the forward domain where the _dns-sd._udp subdomains reside. lb._dns-sd._udp.0.43.168.136.in-addr.arpa PTR <A DOMAIN YOU CONTROL> e.g. lb._dns-sd._udp.0.43.168.136.in-addr.arpa. PTR example.com. and b._dns-sd._udp.example.com. PTR example.com. b._dns-sd._udp.example.com. PTR dnssd.example.com. dr._dns-sd._udp.example.com. PTR dnssd.example.com. lb._dns-sd._udp.example.com. PTR example.com. lb._dns-sd._udp.example.com. PTR dnssd.example.com. zone dnssd.example.com { .... allow-update { 136.168.43.0/<length>; }; }; Now if the devices are truly capable of doing service discovery properly this is all you should need to do beyound rebooting the devices to get them to register themselves. Hopefully I haven't left anything out or got something wrong as I am yet to do this in real life. Mark In message <fd2d7867-c934-de08-9e4b-90a0d07f8...@csub.edu>, "Michael W.
