1.6 Saving the IP Address in the UTN Server
Why IP Addresses? An IP address is used to address network devices in an IP network.
TCP/IP network protocols require the storing of the IP address in the
UTN server so that the device can be addressed within the network.
How Does the UTN
Server Obtain IP
Addresses?
The UTN server is able to assign itself an IP address during the initial
installation. Boot protocols are used to assign an IP address
automatically to the UTN server. Upon delivery, the boot protocols
’BOOTP’ and ’DHCP’ are enabled.
Once the UTN server is connected to the network, it checks whether
an IP address can be obtained from the boot protocols BOOTP or
DHCP. If this is not the case, the UTN server assigns itself an IP
address from the address range (169.254.0.0/16) which is reserved
for ZeroConf.
Once the UTN server has automatically received an IP address via a
boot protocol, you can save a freely definable IP address in the UTN
server. The UTN server’s assigned IP addresses can be determined and
changed using the software tools, “SEH UTN Manager” and
“InterCon-NetTool”; see: Ö16.
Different methods for the assignment of the IP address are described
in the following.
Automatic Methods
of IP Address
Assignments
• ’ZeroConf’ Ö13
• ’BOOTP’ Ö13
• ’DHCP’ Ö13
• ’Auto Configuration (IPv6 Standard)’ Ö14
Manual Methods of
IP Address
Assignments
• ’InterCon-NetTool’ Ö14
• ’SEH UTN Manager’ Ö14
• ’myUTN Control Center’ Ö15
• ’ARP/PING’ Ö15

General Information
myUTN User Manual 13
ZeroConf
If no IP address can be assigned via boot protocols, the UTN server
assigns itself an IP address via ZeroConf. For this purpose, the UTN
server picks an IP address at random from the address range
(169.254.0.0/16) which is reserved for ZeroConf.
You can use the domain name service of Bonjour for the name
resolution of the IP address; see: Ö38.
BOOTP
The UTN server supports BOOTP, which means that the IP address of
the UTN server can be assigned via a BOOTP server.
Requirements ;The 'BOOTP' parameter has been enabled, see: Ö31.
If the UTN server is connected, it asks the BOOTP host for the IP
address and the host name. The BOOTP host answers and sends a
data packet containing the IP address. The IP address is saved in the
UTN server.
DHCP
The UTN server supports DHCP, which means that the IP address of
the UTN server can be assigned dynamically via a DHCP server.
Requirements ;The 'DHCP' parameter has been enabled, see: Ö31.
After the hardware installation, the UTN server asks a DHCP server for
an IP address by means of a broadcast query. The DHCP server
identifies the UTN server on the basis of its hardware address and
sends a data packet to the UTN server .
This data packet contains, among others, the IP address of the UTN
server , the default gateway, and the IP address of the DNS server. The
data is saved in the UTN server .

General Information
myUTN User Manual 14
Auto Configuration (IPv6 Standard)
The UTN server can have an IPv4 address and several IPv6 addresses
at the same time. The IPv6 standard is used to automatically assign
IP addresses in IPv6 networks. When connected to an IPv6 network,
the UTN server will automatically obtain an additional link-local IP
address from the IPv6 address range.
The UTN server uses the link-local IP address to search for a router.
The UTN server sends so-called 'router solicitations' (RS) to the
special multicast address FF02::2. The available router will then
return a router advertisement (RA) containing the required
information.
With a prefix from the range of the global unicast addresses, the
UTN server can compose its own address. It simply replaces the first
64 bits (prefix FE80::) with the prefix that was sent in the RA.
Requirements ;The 'IPv6' parameter has been activated.
;The 'Automatic configuration' parameter has been activated.
To configure the assignment of IPv6 addresses; see: Ö34.
InterCon-NetTool
The InterCon-NetTool has been developed by SEH Computertechnik
GmbH for the administration of SEH network devices. The IP Wizard
of the InterCon-NetTool helps you to configure the TCP/IP
parameters, e.g. the IP address. You can manually enter the desired
IPv4 address and save it in the UTN server using the IP Wizard. To
configure an IPv4 address via the InterCon-NetTool; see: Ö33.
SEH UTN Manager
You can manually enter the desired IPv4 address and save it in the
UTN server using the SEH UTN Manager. To configure an IPv4 address
via the SEH UTN Manager; see: Ö 32.

General Information
myUTN User Manual 15
myUTN Control Center
You can manually enter the desired IP address and save it in the UTN
server using the myUTN Control Center.
• To configure an IPv4 address via the myUTN Control Center; see:
Ö32.
• To configure an IPv6 address via the myUTN Control Center; see:
Ö34.
ARP/PING
The assignment of the IP address to the hardware address can be
done via the ARP table. The ARP table is an internal system file in
which the assignment is temporarily saved (about 15 min). This table
is administered by the ARP protocol.
By means of the 'arp' and 'ping' commands, you can save the IP address
in the UTN server. If the UTN server already has an IP address, the 'arp'
and 'ping' commands cannot be used to save a new IP address.
However, an IP address from the address range (169.254.0.0/16)
which is reserved for ZeroConf can be overwritten by means of the
'arp' and 'ping' commands.
The 'arp' command is used for editing the ARP table. The 'ping'
command transfers a data packet containing the IP address to the
hardware address of the UTN server. If the data packet has been
successfully sent and received, the UTN server permanently saves the
IP address.
The implementation of the 'arp' and 'ping' command depends on the
system used. Read the documentation for your operating system.
Requirements ;The 'ARP/PING' parameter has been enabled, see: Ö31.
Edit the ARP table:
Syntax: arp -s <IP address><hardware address>
Example: arp -s 192.168.0.123 00-c0-eb-00-01-ff
Assign a new IP address to the UTN server:
Syntax: ping <IP address>
Example: ping 192.168.0.123

SEH UTN Manager Versions
The SEH UTN Manager is available in two versions:
• Single-User Version (SEH UTN Manager)
• Multi-User version (SEH UTN Manager + SEH UTN Service)
A major difference between the single-user version and the
multi-user version is the Windows service ’SEH UTN Service’. The
service works in the background and becomes active after the
system start. The service can be controlled by means of the usual
Windows administration methods.
What are the
Differences between
the Versions?
The advantages of the multi-user version are the support of multiple
users and the differentiation between user groups. The multi-user
version distinguishes between the following user groups:
