BIND 9.2.0 Release Notes

New Features
Unsupported Features
Chapter 1 31
This option was used in BIND 8.1.2 to log statistics of the
nameserver at regular intervals. The logging consumes a lot of
memory and degrades the response time.
• multiple-cnames
This option was used in BIND 8.1.2 to allow multiple CNAME
records in violation of the DNS standards. BIND 9.2.0 strictly
enforces the CNAME rules both in master files and dynamic updates.
• has-old-clients
This option is now implemented through the “auth-nxdomain yes”
and “rfc2308-type1 no” options.
• treat-cr-as-space
This option was used in BIND 8.1.2 to make the server treat carriage
return \r characters, the same way as a space or tab character, or to
facilitate loading of zone files on a Unix system that were generated
on an NT or DOS machine. In BIND 9.2.0, both Unix “\n” and
NT/DOS “\r\n” newlines are always accepted.
• use-id-pool
This option is now obsolete as BIND 9.2.0 always allocated query IDs
from a pool.
• fetch-glue
This option was used in BIND 8.1.2 to cause the server to fetch glue
resource records it does not have when constructing the additional
data section of a response.
• serial-queries
This option was used in BIND 8.1.2 to set the maximum number of
concurrent serial number queries allowed to be outstanding at any
given time. BIND 9.2.0 does not limit the number of outstanding
serial queries and ignores the serial-queries option.
• check-names
This option was used in BIND 8.1.2 to check the hostnames as per
standards.
• topology
The topology statement takes an address_match_list and interprets
it in a special way. Each top-level list element is assigned a distance.
