I must also be slow. Can someone tell me how DNSSEC is supposed to 
encrypt my TCP/IP traffic?

        DNSSEC allows you to go from dns name -> CERT in a secure
        manner.   The application then checks that the cert used to
        establish the ssl session is one from the CERT RRset.

        Basically when you pay your $70 or whatever for the CERT
        record you are asking the CA to assert that you have the
        right to use the domain name.  It's expensive because they
        are not part of existing DNS trust relationship setup when
        the domain was delegated in the first place.

        The natural place to look for DNS trust is in the DNS.
