| Description | ||||
| The fetches-per-server option in BIND 9.x configures a limit on the number of outstanding requests (fetches) allowed for a single DNS server. This rate-limiting mechanism helps protect the BIND 9.x server from being overwhelmed by excessive requests to a specific server, particularly when that server is slow or unresponsive. | ||||

Details
Check Text (C-275937r1156959_chk)
Verify fetches-per-server is enabled with an organization-defined number.
Inspect the named.conf file for the following:
options {
fetches-per-server <integer> drop ;
If fetches-per-server is not enabled and set to drop, this is a finding.
Fix Text (F-79944r1123964_fix)
Modify the BIND configuration file (/etc/named.conf ).
Add the fetches-per-server option to the "options" section of the configuration file.
fetches-per-server <integer> drop;
After making changes, reload or restart BIND to apply the new settings.
