Assigning the IP address
Subject to error and alteration
2�2�4 Reserved IP addresses
If the Com-Server is used as a TCP server or UDP peer, it
provides services which other clients in the network can
also make use of as needed. To open a connection, they of
course need the current IP address for the Com-Server, so
that in such situations it makes sense to reserve a particular
IP address for the Com-Server on the DHCP server. This is ge-
nerally done by linking the IP address to the unique Ethernet
address of the Com-Server, which can be found on the sticker
attached to the housing.

Ethernet address
2�4�5 Dynamic IP addresses
Fully dynamic address assignment, whereby the Com-Server
gets a different IP address every time it is restarted or after
the lease time has expired, only makes sense in network
environments with automatic cross-connection between the
DHCP and DNS services. This means when a new IP address is
assigned to the Com-Server, the DHCP server then automati-
cally updates the DNS system as well. The new address is as-
sociated with the respective domain name. If in doubt, consult
your system administrator for detailed information about your
network environment.
