The codes we use at present include: 127.0.0.1 Listed in IADB

Hmmm... listed in my /etc/hosts as well. Am I IADB compliant? It's interesting to see how everyone tries to reinvent LDAP on top of DNS and/or BGP instead of just using the LDAP protocol itself. Somehow the world has gotten the idea that LDAP is an addressbook protocol when, in fact, it is a fairly generic distributed hierarchical database access protocol. IMHO there are two right ways to publish these types of databases. One is to use LDAP and the other is to use an XML protocol like XML-RPC or SOAP. Overloading DNS as a generic database query protocol is just a plain bad idea. At least both LDAP and XML support the concept of a schema which defines the data being transmitted in an unambiguous way and ensures that it can be correctly parsed and decoded. --Michael Dillon
