Chapter 6. Network
This chapter explains the default network configuration and how to change this configuration, and also explains how to
use the included network applications.
6.1. Default Network Connection Mechanisms
In its default state, the Armadillo is configured to have an IP address assigned to it automatically with either DHCP or
Zeroconf so that it can connect to the network. The PC side network connection must also be configured so that it too
correctly connects to the same network as the Armadillo.
6.1.1. DHCP Connections
When the Armadillo automatically connects to the network, it first attempts to use DHCP. When a DHCP server is present
on the network, an IP address is assigned to the Armadillo in accordance with the response from the DHCP server.
If the PC also uses DHCP in the same way, it will by default connect to the same network as the Armadillo.
6.1.2. Zeroconf Connections
If no DHCP server is found, the Armadillo uses a mechanism called Zeroconf (IPv4LL) to assign an IP address.
To connect with an Armadillo configured this way, the PC must connect to the same network. If Zeroconf is also used
on the PC side, it of course can do so without problem.
Note: Zeroconf is called Automatic Private IP Addressing (APIPA) in Windows. Zeroconf uses an address from a specific
range (169.254.0.1 - 169.254.255.254) with a subnet mask of 255.255.0.0. This IP address block is reserved by IANA
(Internet Assigned Numbers Authority).
It is also possible to connect to a Zeroconf network by configuring a static IP address. The PC can connect to the same
network by using an IP address from the 169.254.0.1 - 169.254.255.254 range with a subnet mask of 255.255.0.0.
While it is possible that a static IP address selected at random will overlap with the one selected by the Armadillo, this
will not be a problem. As the Zeroconf on the Armadillo will detect transmission from another host using the same IP address
and quickly change its own IP address, the Armadillo and PC will be able to differentiate each other after a brief period of
time.
6.2. Changing Network Configuration
The following explains how to change the network settings on the Armadillo.
Please consult a network administrator for help with network connections.
