'Local' names questions
I have a couple questions about draft-ietf-dnsind-local-names-07.txt.
I apologize if all of this discussion has already been covered in the
WG.
1. Why is 'local' defined to be a TLD at all? Why not specify that
it *only* has private meaning?
2. I don't really understand the assignments of qualified local names
as discussed in the draft. In the figure in section 2, private IP
addresses for privhost1 is given, as an example in section 3, as
privhost1.a2.local. How was 'a2' arrived at here? Would this
require registration under '.local'?
I understand that at the .local TLD privhost1.local would very
easily be ambiguous.
3. Would the top level 'local.' DNS servers resolve different local
name domains (such as 'a2.local' in the example in the draft)?
4. Why shouldn't the default for local name resolution be to use
the local version of the .local zone? The following text implies
that the default behavior would be the same as for global name
resolution. It seems to me that local domains would normally
be deployed autonomously, that is, administered purely within a
given site.
It is also possible for an enclave to locally configure its own
version of the .local zone. Depending on its enclave boundary
implementation, it might be able to constrain all of its internal
references to .local to use its own variant version. This version
could have whatever private addresses were desired for the name
servers involved. Such a configuration MAY be used, but it is
recommended that the globally accessible .local specified herein be
used for uniformity. That way, even a unconstrained resolver
starting from the normal root servers (i.e., an "out of the box"
resolver) will correctly resolve or fail to resolve names under
.local depending on the resolvers location in the network as
specified herein.
5. Am I right in assuming that the local name, in a network with no
official 'qualified' local domain, would be just <host>.local?
I am interested in the problem of 'zero configuration networking'.
In such a network, a device (say a microwave oven) would come
preconfigured with a local domain name (say "Zaposonic3243.local",
where Zaposonic3243 would be the model of the oven). I understand
that if I bought two such devices, they would be aliases of each
other until one or both were reconfigured.
I am not on the namedroppers mailing list. Please respond to me directly.
