COMPOINT-LIB manual, Version 1.0
TCP/IP Network
COMPOINT-LIB in the TCP/IP network
Each participant of a TCP/IP network has one unique IP number and can thus be
identified clearly. These IP numbers are composed of 4 figures in the range from 0 to 255
(octet) separated by a point:
Examples: 149.213.48.93 or 109.89.1.3 or 56.3.58.13
You can distinguish 4 different types of addresses:
1. Addresses of type A
For addresses of type A the first octet determines the network address (0 -127) and the
other three octets determine the PC address. I.e. the participants of such a network only
have the first value in common, all other values are different (e.g. 121.213.13.22,
121.122.30.89 , 121.23.111.1, etc.). This type of addressing is only used in very large
networks as altogether there are 256 times 3 addresses available.
2. Addresses of type B
The addresses of type B determine the first two octets of the network address and the PC
names are distinguished by the two latter octets. Some IP numbers of a type B network:
139.1.0.1, 139.1.234.89, 139.1.45.9, etc.. The maximum number of network participants is
determined by 256 times 2 and the first value of the IP number is generally in the range
from 128 to 191.
3. Addresses of type C
The addresses of type C determine the first 3 octets of the network address and
determine the PC name with the 4
th
octet. Please find following some examples of a type
C network: 101.83.12.03, 101.83.12.243, 101.83.12.120 . The maximum possible number
of participants in the network is limited to 256 and this way many networks can be address
with only a few PCs. The typical value range for the first value of the IP number is from
192 to 223.
4. Addresses of type D
For the addresses of type D the four highest bits of the IP number = 1110 and this results
in a value range of 224 - 239 for the first value of the IP number. The types of addressing
are called Multicast and are used for more recent IP protocols.
On a TCP/IP network the COMPOINT-LIB has to be assigned with a clear and correct IP
number according to the above mentioned classes

COMPOINT-LIB manual, Version 1.0
TCP/IP Network
Functional principal of the COMPOINT-LIB in the TCP/IP network
For the communication of 2 participants of a TCP/IP network over different types it is
decided how the Subnet mask had been defined. Each participant of the network
determines with this mask which other IP participant can be reached. The target address
will this way be linked with the Subnet mask bit by bit AND – the result will be compared to
the target address which is extended by the Subnet mask. The value 0 in the Subnet
mask means that the address indication will not be analyzed in this place and the value
255 means that an analysis takes place.
Please find below some examples:
Proper address 123.49.89.13
Subnet Mask 255.255.0.0
The addresses 123.49.xxx.xxx, e.g. 123.49.200.10 or 123.49.30.3, etc. can be reached
but not 123.50.200.10
Proper address 123.49.89.13
Subnet Mask 255.255.255.0
The addresses 123.49.89.xxx, e.g. 123.49.89.10 or 123.49.89.3, etc. can be reached
but not 123.49.200.10
In order to have LAN connections over the router also a connection over the Subnet mask
needs to be released and the routing needs to be configured with a default Gateway entry
over the corresponding router.

COMPOINT-LIB manual, Version 1.0
TCP/IP Network
Setting up the IP address with DHCP.
Functional principal:
The COMPOINT-LIB contains all mechanisms of the DHCP (Dynamic Host Configure
Protocol) and can therefore be assigned to an IP address by a DHCP server. The IP
address can be firmly assigned (static assignment) or can be variable within an IP address
space according to configuration of the DHCP server. The additional properties of the
DHCP such as Lease Time, etc. are completely supported by the COMPOINT-LIB.
Please find following a typical entry on a Windows NT DHCP server:
1.) The COMPOINT-LIB is operable
2.) DHCP needs to be connected for network interface in COMPOINT-LIB
(default configuration)
3.) The DHCP has to be available in the LAN segment
4.) Switch on the COMPOINT-LIB
