Hi Randy,<br><br>Printers already commonly publish themselves in SLP (if servers are<br>present) and LDAP/Active Directory automatically.<br><br>Adding the IPP Everywhere MDNS requirement for DNS-SD publish<br>of LOC and TXT records is a matter of parity in discovery protocols.<br>

Hi Mike,<br>
<br>
You're right about multicast DNS not requiring site administration, but dynamic DNS is only designed to update A/AAAA records in a zone. �I'm not aware of anyone using dynamic DNS to update TXT, SRV, or other resource records. �I haven't seen this done.<br>
