When an HTTPS unit is added with a hostname, the hostname will be used to communicate
to the unit.
When in HTTPS, the hostname is always used to communicate with the unit and to validate the
certificate’s subject name. If the Archiver is unable to resolve the hostname used, it will
then try to connect using the last known IP address.
NOTE: if the hostname points to an
invalid IP address, it will be used and the connection to the unit will fail.
In HTTP, the hostname will be used to resolve the unit's IP address unless the
Allow hostname address resolution option is cleared in an Axis unit
or if UseDNS is added to the extension's advanced settings with value
"0" for the other extensions.
