Get Automatically from ISP: Your ISP uses DHCP to assign your DNS servers.
Your ISP automatically assigns this address. This option uses the DNS servers
assigned by the ISP for the IPv4 connection.
Use These DNS Servers: If you know that your ISP requires specific servers, select
this option. Enter the IP address of your ISP’s primary DNS server. If a secondary
DNS server address is available, enter it also.
8. Select an IP Address Assignment radio button:
Use DHCP Server: Use this method if devices on the LAN cannot receive an IPv6
address through auto configuration but must receive the IPv6 address through
a DHCP server.
Auto Config: This is the default setting.
This setting specifies how the router assigns IPv6 addresses to the devices on your
home network (the LAN).
9. (Optional) Select the Use This Interface ID check box and specify the interface ID
that you want to be used for the IPv6 address of the router’s LAN interface.
If you do not specify an ID here, the router generates one automatically from its MAC
address.
10. (Optional) In the MTU Size (in bytes) field, enter a size in bytes.
The default size for this type of IPv6 connection is 1480 bytes.
11. Click the Apply button.
Your settings are saved.
Manage the MTU size
The maximum transmission unit (MTU) is the largest data packet a network device
transmits.
MTU concepts
When one network device communicates across the Internet with another, the data
packets travel through many devices along the way. If a device in the data path uses a
lower maximum transmission unit (MTU) setting than the other devices, the data packets
must be split or “fragmented” to accommodate the device with the smallest MTU.
The best MTU setting for NETGEAR equipment is often the default value. In some
situations, changing the value fixes one problem but causes another. Leave the MTU
unchanged unless one of these situations occurs:
