1 Introduction

National and International Meshes are formed by linking District Meshes together.

2 Community Mesh IPv4

Please refer to RFC 3330 for details on current international IPv4 address assignment.


2.1 IPv4 Districts

Each District has 16,777,216 mesh IPs (255.0.0.0 subnet mask, /8) divided into 1,024 Areas. Currently, all IPv4 Districts all use IP addresses from the 10.0.0.0 subnet.

There are 1,024 Areas within a District (e.g. with addresses 10.0.0.0/8):
     1.     10.0.0.0 - 10.0.63.255     (Reserved)
     2.     10.0.64.0 - 10.0.127.255
     3.     10.0.128.0 - 10.0.191.255
     4.     10.0.192.0 - 10.0.255.255
     5.     10.1.0.0 - 10.1.63.255
     6.     10.1.64.0 - 10.1.127.255
     7.     10.1.128.0 - 10.1.191.255
     8.     10.1.192.0 - 10.1.255.255
                ... ...
                ... ...
                ... ...
1021.     10.255.0.0 - 10.255.63.255
1022.     10.255.64.0 - 10.255.127.255
1023.     10.255.128.0 - 10.255.191.255
1024.     10.255.192.0 - 10.255.255.255


2.2 IPv4 Areas

Each Area has 16,384 District IPs (255.255.192.0 subnet mask, /18) divided into 1,024 Nodes. Each Node has 16 District IPs (255.255.255.240 subnet mask, /28).


There are 1,024 Nodes within an Area (e.g. with addresses 10.0.64.0/18):
     1.     10.0.64.0 - 10.0.64.15
     2.     10.0.64.16 - 10.0.64.31
     3.     10.0.64.32 - 10.0.64.47
     4.     10.0.64.48 - 10.0.64.63
     5.     10.0.64.64 - 10.0.64.79
     6.     10.0.64.80 - 10.0.64.95
     7.     10.0.64.96 - 10.0.64.111
     8.     10.0.64.112 - 10.0.64.127

1024.     10.0.127.240 - 10.0.127.255


2.3 IPv4 Nodes

Each node can have 32,768 Node IP addresses. Node IPs use the second half of the private class-C addresses in 192.168.128.0/17 range for devices within a node (192.168.128.0 - 192.168.255.255).

  1. Private Subnet Addresses should be assigned 256 at a time from bottom up (from 192.168.128.0/24)
  2. Public Subnet Addresses should be assigned 256 at a time from top down (from 192.168.255.0/24)

Subnet Masks are adjusted as the subnets grow.

Non Community Mesh private networks should NOT use the above address range (192.168.128.0 - 192.168.255.255). That is, external private networks should use the range 192.168.0.0 - 192.168.127.255.


2.4 IPv4 Internal

The private class-B address range (172.16.0.0 - 172.31.255.255) is used for internal communication between districts. Normally 16 of these IP addresses are assigned to each district.

The link local address range (169.254.0.0 - 169.254.255.255) is used for internal communication between areas. Normally 1 of these IP addresses is assigned to each area.


3 Community Mesh IPv6

Community Mesh was designed for IPv6, although a lot of progress has been made recently on IPv6, a large number of hardware, software and networks are still not IPv6 compatible. We will be using the "private addresses" of IPv4 as an interim measure, with progressive conversion to the "unique site local addresses" of IPv6.

Type IPv4 IPv6
Districts per Planet 131,072 16,777,216
Areas per District 1,024 1,048,576
Nodes per Area 1,024 1,048,576
District IPs per Node 16 65,536
Node IPs per Node 32,768 65,536

IPv4 District IP addresses are only unique within a District (all IPv4 Districts uses the SAME 10.x.x.x IP address range).
IPv6 District IP addresses are unique worldwide - using a single /48 prefix (further expansion is possible with more than one IPv6 prefix).

  1. Channel 149 : 5.745 GHz
  2. Channel 152 : 5.760 GHz
  3. Channel 153 : 5.765 GHz
  4. Channel 157 : 5.785 GHz
  5. Channel 160 : 5.800 GHz
  6. Channel 161 : 5.805 GHz
  7. Channel 165 : 5.825 GHz


The above list include some channels that are NOT in the IEEE standard e.g. used by vendors in "turbo mode" operation (for bonding of two adjacent 20MHz channels).

When operating multiple channels on the same site, pick channels that are as far apart as possible from each other.

4.1 Australian WiFi Channels

Let's hope the Australian government opens up more channels, in the meantime, this is what we have:

Channels 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 36*, 40*, 42*, 44*, 48*, 50*, 52*, 56*, 58*, 60*, 64*, 149, 152, 153, 157, 160, 161, 165

Those channels with * above are for indoors use only and are normally the only channels supported by mass produced customer 5G WiFi equipment. Which is a REAL PAIN, since Community Mesh relies on cheap mass produced WiFi equipment to send signals both indoors AND outdoors to each other. This is one of the reasons why initial Community Mesh deployments are all using channels 01 to 13 instead of channels 149 to 165.
