No. Or at least, the point of having something like a link-local name resolution protocol is that you can use the same interfaces to look up the local names when using the link-local protocol, as you do when looking up real DNS names when using the real DNS protocol. That way all the existing applications work and don't need to be changed. Otherwise you would be suggesting building an entirely new protocol and application stack, with changes to every application to support the link-local scheme, which is obviously out of the question. So what you're saying is that you're opposed to whole concept of link-local name resolution. And that therefore you favour LLMNR because it doesn't (in your view) provide it ! Of course you are wrong on this last point - LLMNR will be deployed behind the same APIs currently used to do real DNS lookups. I think that what you've done with your posting, really, is demonstrate Stuart Cheshire's claim that LLMNR is for blocking effort ! > IMO, local names and a lookup service for local names would be extremely > useful, but neither the names nor the query interface should look much > like DNS - the names should look different because otherwise there's too > much potential for confusion with DNS names, and the query service > should look different because local name lookup service probably can't > make the same kinds of consistency or stability assurances that DNS does. To say that, is to say that work on LLMNR should never have been started. There is no demand for a local name resolution protocol which doesn't present a DNS API to applications. You may well say that the whole concept of local name resolution, if it must be presented to applications behind a DNS API, is a bad idea and I have some sympathy with that view - but that's no argument for LLMNR against mDNS ! Stuart seems to be claiming that the people who first told him to take is mDNS away from the IETF, and LLMNR's authors, have that view - and that LLMNR is the result of those people producing a protocol which is intended to look enough like mDNS to fool people but is deliberately _not_ intended to do any of the things that mDNS is good for !
