DNS Blacklist

The "DNS Blacklist" Diagnose checks the availability of the DNS Blacklist Servers that are configured in the Reddoxx Appliance and the provided optional DNS Blacklist Servers.
This is useful to test how fast each of the DNS Blacklist Servers answer, in order to exchange slow reacting servers.
Additionally it is checked, whether the provided IP is listed on one of the Blacklist Servers.

  • Warning, if the Server runs into a Timeout
  • Warning, if the IP Adress is listed on a Blacklist Server
  • Error, if the Blacklist Server doesnt reply or is not available
