One of the key things about helping at an event like LCA08 is documenting things so that the team won't have to suffer the things you went through!
So begins the process of dumping ones brain to the Wiki...
Hopefully this might help others in their journey into building their networks =)
Hi
The map and network info here ...

... indicates that I should be able to pass packets south of VK5TTY .. however what are the ips down there??
TIA

When a router receives a packet of information (as it does thousands of times per second) it inspects the IP Address of that packet, and based on that, can make decisions on which physical path to send it through.
This process is known as routing the packet. Special software protocols have been created to support the routing of network traffic between subnetworks. These protocols operate with ‘smart’ algorithms that can adapt the flow of network traffic when problems occur. Protocols such as Border Gateway Protocol (BGP) and are widely used across the Internet today.
Computers on a network communicate with each other using a special numbered addressing system. This is known as Internet Protocol (or IP). Each computer has a unique IP Address, which is four sets of numbers from 0-255, separated by a decimal point. This gives a total possible address space from 0.0.0.0 to 255.255.255.255. For example: 203.152.23.202 is an Internet IP Address.
IP addresses can be grouped into smaller logical segments of the entire address space, which can then be assigned to computers in a LAN. Breaking up IP Address space into smaller sub-networks is known as Subnetting.
This allows for logical control of data between LANs, and maps well onto the physical network design outlined.
Groups of computers can be connected in many different configurations.
A simple Local Area Network (LAN) consists of a few computers, which are directly connected to each other.
This allows for high-speed communication between the participating machines, but offers little flexibility for adding more clients. Networks like this are generally confined to a relatively small area, such as a home, business or office.
As more clients are added to the LAN, we require more efficient control of network traffic. This is achieved through the deployment of devices such as Switches and Routers.
Air-Stream uses private addressing from the 10/8 range utilising 10.96.0.0/11, this is designed to allow interconnection into wireless networks around Australia should the day ever come.
These are:
General rule of thumb is that an Access Point will be assigned 1x/27 for the Nodes hanging off it, 1x/27 for the Local LAN at the access point if applicable and each node will be assigned a single address from the Access Points /27 pool to which they then can route their very own /27 to if they wish.
