(3) Ethernet Interface
Administrator may configure IP address, subnet mask, broadcast address, gateway address, and
DNS addresses of NetServer. For broadcast address, administrator may set it automatically by
clicking ‘Get From Netmask’ button after assigning IP address and subnet mask. When the
addresses are not assigned properly, any user cannot access NetServer from local or remote network.
Even on the local network, a user is not able to access if administrator does not assign a proper IP
address to NetServer. Please refer to appendix 3 ‘Utilizing IP Address on Local Network’ for more
detailed information.
This interface is mainly used for Internet dedicated line and LAN, and sometimes for xDSL line as
it is explained on ‘DHCP Client Protocol’ setting.
MTU Size : Depending on network type, administrator may set data packet size with this menu to
utilize the network at most effectively.
DNS Server IP Address: This is used when you register your NetServer on dynamic IP registration
list of WRS (NetServer Registration Server). WRS has its domain name of ‘NetServer.to’ and the
domain name is registered on DNS servers on the world. When your NetServer asks the DNS server
on your network, the DNS server resolves the corresponding IP address of ‘NetServer.to’ and
informs the IP address to your NetServer. Then your NetServer may connect WRS. So it is
necessary you get information on DNS server’s IP address and enter into the blanks.
DNS (Domain Name System)
DNS (Domain Name System) is to map between IP
address and domain name. Every network
device on the world has its IP address to be connected on Internet. And the device is to be
connected not with its domain name but with its IP address. Common users are not familiar
with IP addresses but with domain names.
If a user accesses a certain network device with its domain name, DNS
server resolves the
domain name into an IP address of the device and replies the result to the user.
A lot of DNS
servers are run on Internet worldwide.
