Maximum cache Time-to-Live (TTL) defines the length of time that a positive response to a DNS query is held in cache. In Address Manager, you can set the time in seconds, minutes, hours, or days. On the Windows server, the time is shown in seconds.

When deploying to Windows servers, you can set this option at the following levels:

  • Configuration
  • Server Group
    Attention: Server Groups only support BlueCat DNS/DHCP Servers.
  • Server
  • View
