16 What's new in Zabbix 7.0.11

Asynchronous DNS resolution

The agent poller and SNMP poller can now be configured to use the c-ares library (version 1.16.0 or newer) instead of the libevent DNS resolver. This allows for potentially faster and more flexible DNS resolution.

To enable c-ares, Zabbix must be configured with the --with-ares option.

Note that starting from c-ares 1.31.0, DNS caching is enabled by default.
