What are the benefits of wildcards, other than a smaller zone file?
Knowing what we do now, would wildcards be added to DNS?
They are necessary for some kinds of applications. I use wildcard A or
CNAME RRs for some webservers that use the hostname for database searches.
Another webserver use mass virtual hosting to serve locally mirrored
websites, also with the use of wildcard RRs. A wildcard MX is a nice thing
when you really wnat to get any mail, even those to constructed addresses
(honeypot for early worm/spam detection).
For some applications they reduce the number of DNS modifications
necessary. When allowing users to create new FQDNs for use in mail
addresses, a wildcard MX can be a nice thing to have.
