In order to reach consensus on the issue of wildcards, we would like
working group participants to answer the following questions. Please
read through them first before responding.
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).
2) Do you feel a MARID solution needs the capability of DNS wildcards?
3) If you answered "yes" to both of the above questions, then is it
reasonable to expect DNS wildcard capability only with the new record
type and not the TXT usage (because TXT may be defined to use a
prefix)?
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).
