in the network have the identical initial bits for their IPv6 address; the number of
common initial bits in the network's addresses is set by the prefix length field.
In the DHCPv6 field, choose to disable or enable the DHCPv6 server. If enabled,
the Cisco RV180/RV180W assigns an IP address within the specified range plus
additional specified information to any LAN endpoint that requests DHCP-served
addresses.
Choose the DHCP mode. If stateless is selected, an external IPv6 DHCP server is
not required as the IPv6 LAN hosts are auto-configured by the Cisco RV180/
RV180W. In this case, the router advertisement daemon (RADVD) must be
configured on this device and ICMPv6 router discovery messages are used by the
host for auto-configuration. There are no managed addresses to serve the LAN
nodes.
If stateful is selected, the IPv6 LAN host will rely on an external DHCPv6 server to
provide required configuration settings.
(Optional) Enter the domain name of the DHCPv6 server.
Enter the server preference. This field is used to indicate the preference level of
this DHCP server. DHCP advertise messages with the highest server preference
value to a LAN host are preferred over other DHCP server advertise messages.
The default is 255.
Choose the DNS proxy behavior:
• Use DNS Proxy—Check this box to enable DNS proxy on this LAN, or
uncheck this box to disable this proxy. When this feature is enabled, the
router acts as a proxy for all DNS requests and communicate with the ISP's
DNS servers (as configured in the WAN settings page).
• Use DNS from ISP—This option allows the ISP to define the DNS servers
(primary/secondary) for the LAN DHCP client.
• Use below—If selected, the primary/secondary DNS servers configured are
used. If you chose this option, enter the IP address of the primary and
secondary DNS servers.
Enter the lease/rebind time. Enter the duration (in seconds) for which IP addresses
will be leased to endpoints on the LAN.
Click Save.
