2. Basic Network Configuration
As said before, each device has a personal and unique IP. For readability purposes, humans
typically work with IP addresses in a notation called dotted decimal. This notation places
periods between each of the four numbers (octets) that comprise an IP address. For example,
an IP address that those computers see as:
00001010 00000000 00000000 00000001
is written in dotted decimal as:
IP= 10.0.0.1
Despite we have the possibility to assign any IP (theoretically from 0.0.0.0 to 255.255.255.255),
to avoid network conflicts and collisions we must keep it confined within the called “private
ranges”:
IP address private range Max. number of addresses
10.0.0.0 – 10.255.255.255 16,777,216
172.16.0.0 – 172.31.255.255 1,048,576
192.168.0.0 – 192.168.255.255 65,536
By default all Ecler networked devices come out from factory with the following network
configuration:
IP: 192.168.0.100
Mask: 255.255.255.0
Gateway: 192.168.0.1
UDP Port: 2210
In this document we will use indistinctly any IP private range for the examples.
The devices’ network configuration must be manually entered with nor DHCP server
(automatic) at this time, neither APIPA DHCP failover (169.254.X.X range).
The role of the network mask is to restrict the range of IPs, thus allowing what we call
subnetting. Two or more devices can only communicate to each other if they are in the same
IP range, or under the same mask (subnet):
