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:

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: Ö36.
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
