Network
DHCP (Dynamic Host Configuration Protocol) is a client/server protocol for
dynamically allocating IP addresses and network parameters. The IP
addresses are requested by the DHCP clients (PCs in the network) on the
DHCP server (for example, a router or the Internet service provider). The
DHCP server takes these IP addresses from a set address pool and sends
them to the client. In addition, the client receives additional information
(for example, the addresses for the standard gateway and DNS server). The
IP address is temporarily allocated for a certain amount of time. If the
address is no longer required by the client, the server has access to it again
and can allocate it to another client.
IP address is received automatically.
The IP address must be assigned manually. Addtional entries must be
made:
IP adress
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.
