RE: Towards resolution on Wildcards

2004-06-09 13:10:11

1) During the MARID interim meeting, Ted Hardie suggested a dual
record 
type approach whereby TXT would be used in servers incapable of 
supporting a new record type, but more capable servers would use a new

record type (specifically defined for MARID).  Do you feel this is a 
workable solution? (Reference Margaret Olson's description here: 
http://www.imc.org/ietf-mxcomp/mail-archive/msg01512.html).

No.  As previously discussed at length, if you're in a corporate
environment behind a firewall created using Microsoft Internet Security
and Acceleration Server, you are completely incapable of querying for a
new record type, unless and until both your machine's OS and the
firewall's copy of ISA Server have been updated.  Such updates don't yet
exist, and have probably already missed the boat for Longhorn.


2) Do you feel a MARID solution needs the capability of DNS wildcards?

Required? No.  Desirable? Yes.


4) If you answered "no" to either (1) or (2), then do you feel it is 
acceptable for TXT reuse to specify a prefix and that environments 
needing DNS wildcard behavior may do so at the risk of collision or 
other side-effects? (Reference 
http://www.imc.org/ietf-mxcomp/mail-archive/msg01691.html for 
discussion of this).

Yes.
