From the drop-down list, select how IPv4 is configured:

 


Using DHCP. The ReadyNAS functions as a DHCP client, and the IPv4 settings are automatically configured by a DHCP server on your network.

Manually. You need to enter the IPv4 address and subnet mask for the ReadyNAS, and the router through which the ReadyNAS is connected to the network.

IPv4 Address

Enter the IPv4 address for the ReadyNAS.

 

 

Manual configuration only.

Subnet Mask

Enter the subnet mask for the ReadyNAS.

Router

Enter the IPv4 address for the router through which the ReadyNAS connects to your network.

Configure IPv6

From the drop-down list, select how IPv6 is configured:

 


Automatically. The ReadyNAS is configured with an IPv6 address through stateless auto-configuration without the requirement of a DHCPv6 server on your network. The ReadyNAS does need to be connected to the Internet for stateless auto-configuration to function.

Using DHCP. The ReadyNAS functions as a DHCPv6 client. The IPv6 settings are automatically configured by a DHCPv6 server on your network.

Manually. Enter the IPv6 address and prefix length for the ReadyNAS and the router through which the ReadyNAS is connected to the network.

Router

Enter the IPv6 address for the router through which the ReadyNAS connects to your network. The default setting is unknown.

 

 

Manual configuration only.

IPv6 Address

Enter the IPv6 address for the ReadyNAS.

Prefix Length

Enter the prefix length for the ReadyNAS. The default prefix length is 64.


Note: NETGEAR recommends that you use DHCP address reservation to make sure that the DHCP server always assigns the same IP address to the interfaces of the ReadyNAS. The MAC addresses of the physical interfaces are shown on the Network screen.

Note: If you enter an IP address manually, you must provide DNS server information if you want to access your ReadyNAS system over the Internet. For more information on DNS, see the What are the basic network concepts I need to understand before operating my ReadyNAS OS 6 storage system? If the IP address changes, your browser loses its connection to your storage system. To reconnect to your ReadyNAS system, use ReadyCLOUD to rediscover your device. For more information, see the How do I find my ReadyNAS OS 6 storage system on my network and set-up ReadyCLOUD?
