LAN Settings (IPV6):
IP Address (IPV6) – This field displays the IPV6 address of your LAN. An IPV6 address has eight
groups of four hexadecimal digits (0-9, a-f). The groups are separated by colons (:) e.g.
2001:0db8:85a3:0000:0000:8a2e:0370:7334. A double colon (::) is shorthand for an address of
all zeros.
Prefix Length V6 – Length of the network portion of the IPV6 address.
Link Local Address (IPV6) – IPV6 address that can be used only on this network.
DHCP Server Settings (IPV6):
Enable DHCP Server (IPV6) – Click this checkbox to enable the use of a V6 Dynamic Host
Configuration Protocol (DHCP) Server on your network.
DHCP is a set of rules used by devices such as a computer, router, or network adapter to allow
the device to request and obtain an IP address from a server which maintains a list of addresses
available for use.
The DHCP server ensures that all IP addresses are unique, e.g., no IP address is assigned to a
second device while the first device's assignment is valid (its lease has not expired).
Without DHCP, the IP addresses must be entered manually at each computer in an organization
and a new IP address must be entered each time a computer moves to a new location on the
network.
Start IP Address (IPV6) – Enter the starting address in the range of IPV6 addresses that the DHCP
Server will be allowed to assign to a network device.
End IP Address (IPV6) – Enter the ending address in the range of IPV6 addresses that the DHCP
Server will be allowed to assign to a network device.
Lease Time V6 – Enter the lease time in seconds before the assigned IPV6 address will expire.
(After the lease time is up, the user is automatically assigned a new dynamic IP address.)
DHCP uses the concept of a "lease" or amount of time that a given IP address will be valid for a
computer or other network device. The lease time can vary depending on how long a user is
likely to require the Internet connection at a particular location. Using very short leases, DHCP
can dynamically reconfigure networks where there are more computers than available IP
addresses, such as educational environments.
DNS Override:
Enable DNS Override – Click this checkbox to enable DNS Override and replace the DNS server
addresses provided by your service provider.
Primary DNS Server IP – Enter the IP address of the primary DNS server. Your ISP will provide
this information.
