Note: Both IR1101 and IR1800 series devices provide the same Domain Name System (DNS) and Network Transport Protocol (NTP) functionality. DNS/NTP functionality is unavailable in IR800 devices.
DNS enables a Domain Name Server to translate domain names into IP addresses.
NTP is a networking protocol used for clock synchronization between computer systems (laptops, servers, or routers).
Primary LAN DNS IP Address: A required field that provides the primary DNS IP address. The default primary IP Address is: 22.214.171.124.
Secondary LAN DNS IP Address: A required field that provides secondary DNS IP address for the backup server. The default secondary IP Address is: 126.96.36.199.
Set time via NTP or manually set time by selecting the time zone: A required field that provides the actual time from a reference clock. The time server can be of a local network or an internet GPS time as the reference clock for NTP. (Use the ntp rfclock gps command.)
Primary Network Time Sever: This is a designated server that is reachable by the device whose function is to manage network resources.
Secondary Network Time Server: This is a designated server to serve as a backup whose function is to manage network resources.
To configure DNS/NTP settings:
(Required) Enter the Primary LAN DNS IP Address.
(Required) Enter the Secondary LAN DNS IP Address.
(Required) Select the Time via NTP or select the Time Zone.
(Optional) Enter the Primary Network Time Server.
(Optional) Enter the Secondary Network Time Server.
