This is useful in DNSSEC-signed zones because when
rolling to a new DNSKEY, the old key needs to remain
available until RRSIG records have expired from

Specifies a list of addresses which require responses
to use case-insensitive compression. This ACL can be
used when <command>named</command> needs to work with
clients that do not comply with the requirement in RFC
1034 to use case-insensitive name comparisons when
checking for matching domain names.

client.
</para>
<para>
This can result in slightly smaller responses: if
a response contains the names "example.com" and
"example.COM", case-insensitive compression would treat
the second one as a duplicate. It also ensures
that the case of the query name exactly matches the
case of the owner names of returned records, rather
than matching the case of the records entered in
the zone file. This allows responses to exactly
match the query, which is required by some clients
due to incorrect use of case-sensitive comparisions.

if a zone file defines records of different types with

"WWW.EXAMPLE.COM/AAAA"), then all resposnes for that
name will use the <emphasis>first</emphasis> version
of the name that was used in the zone file. This
limitation may be addressed in a future release. However,
domain names specified in the rdata of resource records

have their case preserved unless the client matches this
