(IP addresses of the form
x.x.x.0
and x.x.x.255 are invalid.
An IP address is a number assigned to a network device (such as a computer) as a permanent address on
the network. Computers use the IP address to identify and talk to each other over the network. Choose a
proper IP address that is unique and valid in your network environment.
Netmask
Setting
E.g., 255.255.255.0
A netmask is used to group network hosts into subnets. When a packet is sent out over the network, the
HT630 will use the netmask to check whether the desired TCP/IP host specified in the packet is on the same
subnet as the HT630. If the address is on the same subnet, a connection is established directly between the
HT630 and the host. If the host is not on the same subnet, the packet is sent to the Gateway address.
Gateway
Setting
E.g., 192.168.1.1
A gateway is a network gateway that acts as an entrance to another network. Usually, the computers that
control traffic within the network or at the local Internet service provider are gateway nodes.
HT630 needs to know the IP address of your network's default gateway computer in order to communicate
with the hosts outside the local network environment.
For correct gateway IP address information, consult your network administrator.
