Appendix D - How to - Network
The following guide aims to familiarize with basic information to setup a TCP/IP
network. Some terms and techniques are explained to conduct you through the
first steps.
Terms
IP Address - Address of a device within your local network. Must be unique.
Example: 192.168.74.15 or 10.0.0.24
Gateway - Address of the network router. When connecting only two devices
‘peer to peer’, use the ip address of one device if it is needed to be declared.
Example: 192.168.74.1 or 10.0.0.20
DNS - Address of Domain Name Server. If you are using a network router with
internet access the IP address of the router can be used here. One may define
a second DNS for use once the first one fails. Example: 192.168.74.1 (same as
gateway) or 8.8.8.8 (Google DNS server) or other…
Network router - device that handles the traffic within a network. Often used
with integrated ADSL modem. Not necessary to setup a peer to peer connection
between two devices only. Has IP address (Gateway).
DHCP - Dynamic host configuration protocol. It is used to assign address
parameters automatically to devices that are connected to a DHCP server. Network
router often act as DHCP server.
NOTE!
You can use the device‘s MAC address (written on the back panel of the M.1K2) in
order to find out the IP address that has been assigned to it by the DHCP server.
Network Mask - a bitmask that splits the network into two parts
• Network contingent: fixed - identical for all devices
• Device contingent: variable - unique for each device, defines the number of
available addresses within the network
The network mask (like the IP address) contains of 32 bits and is often expressed
by decimals. The result of two binary calculations defines both contingents.
Example:
IP address
1100’0000 1010’1000 0100’1010 0000’1111
192.168.74.15
AND network mask
1111’1111 1111’1111 1111’1111 0000’0000
255.255.255.0
network contingent
1100’0000 1010’1000 0100’1010 0000’0000
192.168.74.0
IP address
1100’0000 1010’1000 0100’1010 0000’1111
192.168.74.15
NAND network mask
0000’0000 0000’0000 0000’0000 1111’1111
255.255.255.0
device contingent
0000’0000 0000’0000 0000’0000 0000’1111
0.0.0.15
