IP Numbering Scheme

A portion of the 10.0.0.0/8 private Internet block has been chosen. We have cooperated with Australia so that there will be no IP clashes if we connect to them in the future. At this present time using 802.11abg a cell would be saturated at less that 30 active hosts however this number is expected to grow in the future with advancements in technology. For this reason and to make administration easier a subnet mask of 255.255.255.0 has been chosen. This allows up to 254 hosts per cell. If you want to operate a cell then you will need an IP allocation. At the moment these are given out by sending an email to noodles@nzwirelss.org.

10.224.0.1 > 10.227.254.254 Stub networks

10.228.0.1 > 10.231.254.254 Auckland North up to top of north island

10.232.0.1 > 10.235.254.254 Auckland Central

10.236.0.1 > 10.239.254.254 Auckland South

10.240.0.1 > 10.243.254.254 Auckland to Wellington (Hamilton etc)

10.244.0.1 > 10.247.254.254 Wellington Region

10.248.0.1 > 10.251.254.254 South Island

10.252.0.1 > 10.254.254.254 Christchurch

Naming Standards

SSID: hostname.region.nzwireless.org

E.g. trvln.akl.nzwireless.org

DNS Scheme.

Hosts can be entered directly into the nzwireless.org zone files onto the Internet. his means that the Internet DNS domain nzwireless.org will be used both on the Internet and NZWireless network. E.g. If you want others to access your web server at mynode.nzwireless.org email the DNS administrator which is currently noodles@nzwireless.org.

Routing Protocols

A combination ospf and bgp will be used. Ospf is good in a set and forget mode but is susceptible to link flap. BGP will be used to connect areas using ospf to mitigate this danger. See Simon Anderson’s HOWTO for information on how to setup ospf

Access Point Setup

If you want to run an access point for people to connect to then you will have to get an IP allocation.

Number allocation

There are 254 useable IP address's per subnet.
10.x.x.1 - 10.x.x.10 - Routers
10.x.x.11 - 10.x.x.30 - Servers (web, DHCP, ftp, mail etc)
10.x.x.31 - 10.x.x.126 - Clients from DHCP scope.
10.x.x.129 - 10.x.x.250 - Clients with static addresses.

The static address range can be further split by chopping it up into /29 (255.255.255.248) subnets.

E.g. 10.228.10.0/24 can be split up into 10.228.10.128/29, 10.228.10.136/29………10.228.10.248/29.

The first 2 IP addresses should be used for the routers E.g. 10.228.10.128/29

10.228.10.129 router at AP end
10.228.10.130 router at client end

Channel selection should be 1,6 or 11. Cooperate with other operators in your area.

Client Connection Guidelines

Use a directional antenna it will minimize the noise you pick up from others, and it will minimize the noise you generate for others that are not the intended target of the signal.

It’s always best to get the strongest gain antenna you can afford. Here is a guide to the strength of antenna you should be looking at getting as a minimum. If you use a weak antenna you could adversely effect all the people connected to the AP.

0 > 2KM - 9 to 12 dbi

2 > 4KM - 12 to 16 dbi

4 > 6KM - 16 to 19 dbi

6 or more KM then 23+ dbi

If your client can set RTS turn this on and set it to 200.

You will be assigned an IP address and subnet mask. Use this and check that the subnet mask is correct.
