I'm not really sure what you're saying -- do you mean "EDNS0 is really
needed in DNSSEC testbeds" and
a) "thus EDNS0 is needed" ,
b) "and EDNS0 has been implemented otherwise as well", or
c) something else?
=> b)
AFAIK, most BSDs implment EDNS0 but none of them enable it by default.
=> I believe the problem is that some buggy DNS codes don't like at all
EDNS0 queries.
Linux glibc doesn't implement it.
=> please fix this!
Microsoft does not implement it (not sure).
=> same (if true).
BIND does implement it, but the *point* here is stub resolver support
("node requirements"), not the support in DNS servers.
=> but the deployment issue is more in servers.
AFAIK, we don't have real deployment experience of this. I don't
think we know the full consequences resulting from EDNS0 use because
it hasn't been widely used yet. Thus, I'm a bit hesitant to put
wording as strong as SHOULD here.
=> please ask the dnsop WG if you have a doubt. And look at RFC 3226
even it should be updated.
