Description
50 and the maximum is 253.
Gateway IP Address - Enter a value of the gateway IP address
for this subnet. The value is usually as same as the 1st IP
address of the router, which means the router is the default
gateway.
DHCP Server IP Address for Relay Agent - Set the IP
address of the DHCP server you are going to use so the Relay
Agent can help to forward the DHCP request to the DHCP
server.
DNS stands for Domain Name System. Every Internet host
must have a unique IP address, also they may have a
human-friendly, easy to remember name such as
www.yahoo.com. The DNS server converts the user-friendly
name into its equivalent IP address.
Primary IP Address -You must specify a DNS server IP
address here because your ISP should provide you with usually
more than one DNS Server. If your ISP does not provide it, the
router will automatically apply default DNS Server IP address:
194.109.6.66 to this field.
Secondary IP Address - You can specify secondary DNS
server IP address here because your ISP often provides you
more than one DNS Server. If your ISP does not provide it, the
router will automatically apply default secondary DNS Server
IP address: 194.98.0.1 to this field.
The default DNS Server IP address can be found via Online
Status:
If both the Primary IP and Secondary IP Address fields are left
empty, the router will assign its own IP address to local users
as a DNS proxy server and maintain a DNS cache.
If the IP address of a domain name is already in the DNS
cache, the router will resolve the domain name immediately.
Otherwise, the router forwards the DNS query packet to the
external DNS server by establishing a WAN (e.g. DSL/Cable)
connection.
Force router to use address for DNS - Force Vigor router to
use DNS servers in this page instead of DNS servers given by
the Internet Access server (PPPoE, PPTP, L2TP or DHCP
server).
