NETGEAR 7000 Series Managed Switch Administration Guide Version 7.3 Because Netgear may change IP addresses assigned to its time servers, it is best to access a SNTP server by DNS name instead of using a hard-coded IP address. The public time servers available are time-a, time-b, and time-c. To use this feature, follow the steps below: Enable a DNS name server and access a time server with the following commands: (Netgear switch) (config)#ip domain-lookup (Netgear switch) (config)#ip name-server 192.168.1.1 (Netgear switch) (config)#sntp server time-a.netgear.com where "192.168.1.1" is the public network gateway IP address for your device. This method of setting DNS name look-up can be used for any other applications that require a public IP address, for example, a RADIUS server.
