A.2 - NETWORK OVERVIEW
A.2.1 - Ethernet Addresses
AX3000 terminals (like other devices equipped for Ethernet networking) have a
unique hardware address which is issued by the manufacturer and cannot be
modified. This address is in the form of six hexadecimal bytes, separated by
colons:
AX3000 Ethernet address format:
00:A0:34:xx:xx:xx
Select the '?' command in the horizontal menu of the AX3000 set-up to see the
AX3000 Ethernet address.
A.2.2 - IP Address
Every device connected to an Ethernet network must have a single 32-bit
address which encodes both the network and the host ID. Internet addresses
(sometimes called «IP addresses») are usually written as four decimal numbers
separated by decimal points ('.' character).
There are three main classes of IP address:
7 bits 24 bits
Class A 0 Network Host
14 bits 16 bits
Class B 1 0 Network Host
21 bits 8 bits
Class C 1 1 0 Network Host
Thus every IP address occupies 4 bytes and contains both:
- A network address, and
- A host address.
Note: all devices attached to the same network must have the same class and
the same network address. Each must have a different host address.
