Modifying DNS settings
ZoneRanger may be configured to use DNS servers for name resolution as well as to act as a
Secondary DNS server for managed devices. The DNS Servers section lists the set of DNS
servers ZoneRanger should use for name resolution. The Search Domains section lists the
search domains, if any, used to resolve unqualified names. The Hostnames section provides a
mechanism to map individual IP addresses to hostnames. This is useful when no DNS server is
available. If the Secondary DNS enabled check box is checked, ZoneRanger acts as a caching
DNS server.
Note: Saving any changes on this tab results in a ZoneRanger restart. You must run discovery to
update the ZoneRanger database to reflect any DNS configuration changes.
Setting the ZoneRanger time
The Configuration > System page Time tab is used to set the ZoneRanger time-of-day clock
and optionally, to act as an NTP server for its managed devices. ZoneRanger can either use its
local time or it can synchronize with an external source via the Ranger Gateway, a Time Server
which supports RFC 868, or an NTP server.
