+dnssec-signzone was designed so that it could sign a zone partially, using
+only a subset of the DNSSEC keys needed to produce a fully-signed zone.
+This permits a zone administrator, for example, to sign a zone with one
+key on one machine, move the resulting partially-signed zone to a second
+machine, and sign it again with a second key.
+
+An unfortunate side-effect of this flexibility is that dnssec-signzone
+does not check to make sure it's signing a zone with any valid keys at
+all. An attempt to sign a zone without any keys will appear to succeed,
+producing a "signed" zone with no signatures. There is no warning issued
+when a zone is not signed.
+
+This will be corrected in a future release. In the meantime, ISC
+recommends examining the output of dnssec-signzone to confirm that
+the zone is properly signed by all keys before using it.

presence or absence of a

+ \fBdnssec\-signzone\fR was designed so that it could sign a zone partially,
using only a subset of the DNSSEC keys needed to produce a fully\-signed
zone\&. This permits a zone administrator, for example, to sign a zone with one
key on one machine, move the resulting partially\-signed zone to a second
machine, and sign it again with a second key\&.
+.PP
+An unfortunate side\-effect of this flexibility is that \fBdnssec\-signzone\fR
does not check to make sure it's signing a zone with any valid keys at all\&.
An attempt to sign a zone without any keys will appear to succeed, producing a
"signed" zone with no signatures\&. There is no warning issued when a zone is
not fully signed\&.

examining the output of \fBdnssec\-signzone\fR to confirm that the zone is
properly signed by all keys before using it\&.

- Note some TLDs are not delegation only (e.g. "DE", "LV", "US"

+ DS queries are expected to be made to and be answered by
+ delegation only zones. Such queries and responses are
+ treated as a exception to delegation-only processing
+ and are not converted to NXDOMAIN responses provided
+ a CNAME is not discovered at the query name.
+ </p>
+<p>
+ If a delegation only zone server also serves a child
+ zone it is not always possible to determine whether
+ a answer comes from the delegation only zone or the
+ child zone. SOA NS and DNSKEY records are apex
+ only records and a matching response that contains
+ these records or DS is treated as coming from a
+ child zone. RRSIG records are also examined to see
+ if they are signed by a child zone or not. The
+ authority section is also examined to see if there
+ is evidence that the answer is from the child zone.
+ Answers that are determined to be from a child zone
+ are not converted to NXDOMAIN responses. Despite
+ all these checks there is still a possibility of
+ false negatives when a child zone is being served.
+ </p>
+<p>
+ Similarly false positives can arise from empty nodes
+ (no records at the name) in the delegation only zone
+ when the query type is not ANY.
+ </p>

+ Note some TLDs are not delegation only (e.g. "DE", "LV",
+ "US" and "MUSEUM"). This list is not exhaustive.
