       Title     : Clarifications to the DNS Specification                 
       Author(s) : R. Elz, R. Bush

This draft considers some areas that have been identified as problems with 
the specification of the Domain Name System, and proposes remedies for the 
defects identified.  Eight separate issues are considered:  

+ IP packet header address usage from multi-homed servers,   
+ TTLs in sets of records with the same name, class, and type,  
+ correct handling of zone cuts,    
+ two minor issues concerning SOA records and their use,       
+ the precise definition of the Time to Live (TTL)             
+ Use of the TC (truncated) header bit   
+ the issue of what is an authoritative, or canonical, name, 
+ and the issue of what makes a valid DNS label.     
     
The first six of these are areas where the correct behaviour has been 
somewhat unclear, we seek to rectify that.  The other two are already 
adequately specified, however the specifications seem to be sometimes 
ignored.  We seek to reinforce the existing specifications.   
           
This versions ads two new minor clarifications, to the definition of a TTL,
and to use of the TC bit.  This paragraph will be deleted from the final 
version of this document.

Send a message to:  [e-mail]. In the body type:

NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
							
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
