The IP address must be assigned manually. Addtional entries must be
made:
Dirección IP
Enter IP address. In order to ensure that the data packets reach the correct
recipients, all of the devices in a TCP/IP network require a unique address,
known as the IP address. IPv4 addresses comprise four numbers between
0 and 255 that are separated by a point, for example, 192.168.0.14. The
network addresses are divided up into different classes (Class A to C)
depending on how many computers can be located in a network. Certain
ranges are reserved for the operation of local networks:
•
Class A: 10.x.x.x (for networks with up to 16.5 million PCs)
•
Class B: 172.16.x.x to 172.31.x.x (for networks with up to 65534 PCs)
•
Class C: 192.168.0.x to 192.168.255.x (for networks with up to 254
PCs)
These addresses have no validity on the Internet; this means that data
packets with this sender type or recipient address cannot be transported on
the Internet. However, they can be used in local networks without restriction.
The advantage of this is that if data from a local network configured in this
way comes in contact with the Internet, none of the data on the computers
in the local network can leak out or be accessed externally.
Máscara de subred
Enter the subnet mask. Configuring subnetworks makes it possible to
connect many totally different networks located in totally different areas
because each subnetwork receives its own address and can therefore be
addressed by the router. A subnetwork is created when the IP address is
linked with a subnet mask. If a bit in the subnet mask is set, the corre-
sponding bit in the IP address is considered a part of the network address.
If a bit is not set in the subnet mask, the corresponding bit in the IP address
