The question is relevant to both groups, IMHO, so I will cross post to find the answer.

Use IP addresses or pick a different top level domain to usurp. 

I disagree, so do:

Microsoft encourages the use of .local for private IP space,
http://support.microsoft.com/default.aspx?scid=kb;en-us;296250

DJ Bernstein also talks about using .local for a local tld (creator of djbdns server)
http://cr.yp.to/djbdns/dot-local.html

and, the comp.protocols.tcp-ip.domains FAQ also recommends using .local
http://www.intac.com/~cdp/cptd-faq/section5.html#split_DNS

So, I think the Mac OS implementation is broken if it will not properly resolve .local when I telnet

Putting mdns in the "order" creates a lot of problems. Instead of opening that can of worms, mDNS uses the "local." top level domain to indicate that the name has only local meaning and should be resolved using mDNS.

I think that is a bad solution. local. can have meaning beyond the subnet. In any AS, it is perfectly fine to route 1918 address space, as long as it is blocked beyond the border. Of course a good dns server admin will also block queries for PTR lookups to those addresses at their border.

I was not able to find any RFC or current internet draft that is claiming lordship over the .local domain. In my opinion, mdns is breaking DNS, and telnet'ing to a .local machine is more important to me that Rendezvous. If it is a requirement to reserve the .local tld, then Apple should get on the ball and write the draft and get it turned into an RFC

Hello all,

We (Carnegie Mellon) have re-ip'd all of our access points and wireless switches to use RFC 1918 addresses and have changed their dns domain from sw.cmu.net to sw.cmu.local

Now we are seeing the following:
[TITAN:~] phill% host mg-e-wl-a.sw.cmu.local
mg-e-wl-a.sw.cmu.local has address 172.18.65.152
[TITAN:~] phill% telnet mg-e-wl-a.sw.cmu.local
mg-e-wl-a.sw.cmu.local: No address associated with nodename

Looking into a packet dump while telnetting shows my machine trying to find the host via multicast dns.

Ideally there would be something like

/etc/hosts.conf
order bind,mdns,local

So, do I need to dig my hosts and telnet to them by IP?
