DNS Update Proxy for mDNS
DNS Update Proxy
I recently published a new internet-draft: DNS Update Proxy for mDNS that describes a way to do campus wide service discovery as an alternative to the Discovery Proxy and mDNS Discovery Relay.
The main difference is that instead of delegating subdomains for each IP subnet and translating unicast queries into multicast queries, it pre-populates the unicast authoritative DNS server with all the services it can discover using DNS Update from a proxy listening to multicast DNS.
This allows faster responses and support for DNSSEC with full NSEC next record semantics.
I'm looking for feedback and will also be working on code at the Hackathon @ IETF104 in Prague. Send me a note if you want to work on this MIT licensed code. No Rust knowledge necessary.
Here's a link to the code https://github.com/pusateri/rupdateproxymore ...
