+Registering a subnet
+====================
+
+Before we get started with configuring any sort of routing you first need to get yourself a network allocated to yourself.
+
+## Generating a /48 ULA
+
+We highly recommend you register a new `/48` ULA on the [Ungleich ULA registry](https://ula.ungleich.ch/) - this way we can ensure that the ULA is stored in a global database to prevent clashes (even though the probability is low).
+
+Firstly register a new account with them and you should see the homepage as follows then:
+
+![](/img/prefix_registration/homepage_ungleich.png)
+
+Then go to the "Register random prefix" section:
+
+![](/img/prefix_registration/register_ungleich.png)
+
+On this page fill in the fields, for the `URL` field put `http://deavmi.assigned.network/projects/crxn`. As for the `Organization` set that to `CRXN` and then for the `Network` section set that to be whatever you want to name your network (remember this as we will need it later).
+
+![](/img/prefix_registration/prefix_page_ungleich.png)
+
+After filling this in then hit submit and you should see a blue pop up with your allocation, save this, this is **very important**.
+
+![](/img/prefix_registration/generated_prefix.png)
+
+Now you have successfully allocated yourself a /48 ULA on Ungliech, `fd40:ec65:5b4c::/48`, next we will register it on the CRXN registry.
+
+## Registering your prefix on CRXN registry
+
+Now you will need to register your prefix, i.e. `fd40:ec65:5b4c::/48`, on our [Netbox instance](http://crxn.chrisnew.de/netbox) but you will need to get an account there. What I can recommend is you drop an email to `deavmi@redxen.eu` with your prefix and I can register it for you **or** create an account for you (this way you can register more without having to wait on me and also sub-allocations within your prefix).
+
+Once this is done then we will be ready to start setting up routing!
