CRXN stands for **C**ommunity **R**un e**X**pansive **N**etwork. It's a computer network run by the _community for the community_.
|
||
|
|
We are a dual-stack IP-based network supporting both IPv4 and IPv6. We are focused on having a network that is accessible to all,
|
||
|
|
reliable in terms of having redundant links and diverse. The first part means that we are welcome to anyone who wants to join, the
|
||
|
|
second part means that we focus on having a lot of links between adjacent routers such that if one is to fail there exists a fallback
|
||
|
|
(in the case where the route is only available through said router - if there are more routers then this is mitigated). We also strive
|
||
|
|
to have diverse links - this means linking over the Internet whether it be clearnet or via an overlay network such as Yggdrasil or CJDNS
|
||
|
|
or in the best case creating physical links.
|
||
|
|
|
||
|
|
We aim to create a more open Internet available to everyone and a place to learn about IP routing and networking in general.
|
||
|
|
|
||
|
|
We don't use any particular tooling, the only thing that is standard is the IPv4 and IPv6 part. What tunnelling software, physical
|
||
|
|
mediums or routing daemon you choose to use is up to you - this falls in line with our _open_ ethos.

## About the network
|
||
|
|
|
||
|
|
### Ranges
|
||
|
|
|
||
|
|
The subnets that we use so far are the below private ranges.
|
||
|
|
|
||
|
|
* For **IPv4** we are running on the `10.0.0.0/8` range.
|
||
|
|
* For **IPv6** we are running on the `fd00::/8` range.
|
||
|
|
|
||
|
|
IPv4 note: If we run out we will simply use more private ranges but we will keep out the `192.168.0.0/16` range such that home networks (sane ones) will not have any clashes.
|
||
|
|
|
||
|
|
### The state of the network
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
The network is currently at a mere ~10 nodes with a few services being run over the network such as Mumble and NFS. The only routing
|
||
|
|
daemon being used at this moment is babel and for tunnelling we are using fastd to establish VPN connections at an L2 layer between sites.
|
||
|
|
|
||
|
|
In terms of transit we run fastd over clearnet, Yggdrasil and CJDNS.
|
||
|
|
|
||
|
|
You can view the babel part of the network on the [live router map](http://deavmi.assigned.network:4444).

### Joining the network

There is a tutorial (which is done for the most part) [here](peering.md) which will help you get connected onto the inter-network.
