For your consideration.  I appologise for duplicates. 
The 3rd quarter 1998 in-addr audit results.


-------------------------------------------------------------------------

Refused are servers who refused to transfer the zone.  <REFUSED>

Errors were generally related to the following conditions:  <timeout>

        - delegation to the host level e.g. 2.2.0.192.in-addr.arpa.
	  This is also how the CNAME haq works for CIDR delegations so
	  its hard to tell how much of an error this really is.
        - use of slashes e.g. 0/2.2.0.192.in-addr.arpa.
	  An older method of doing bit-level delegation...
        - alpha strings e.g. test.2.0.192.in-addr.arpa.
        - other non-numberics e.g. #???.2.0.192.in-addr.arpa.
        - failure to fully qualify zones, e.g. the missing "."
	- event-horizon e.g. behind firewall

Other failures seem to be related to server configuration or 
network reachability of either the end system or the nameservers
used in generating the queries.

The no-server number is the total of the refused, error, & other rows.
