-Entity DB
-=========
+Prefix allocation and registration
+==================================
 
-EntityDB holds all network allocations and associated information. All this must be done on this repository: https://codeberg.org/CRXN/entitydb/ or you can send an email to (TODO: add rany's email).
+To simply forward IPv6 traffic on CRXN one only needs an IPv6 link-local address which is always guaranteed to be assigned (most of the time), however normally people join CRXN so that they can _also_ host services (and access others) on the inter-network. Therefore, one needs to allocate a prefix and register it to be able to make use of the network in such a manner.
 
-## Format
+## Generating a prefix (allocation)
 
-Firstly create an entry by creating a directory with your unique username, `deavmi/` for example.
+On CRXN we use addresses within the `fd00::/8` space otherwise known as the ULA-space. We then require users to generate a random ULA which is a subnet within this space with a prefix size of `/48`.
 
-### Networks
+Here is what a ULA would look like: `fd2d:194b:a02f::/48`
 
-All network declarations are created as entries in the file `deavmi/network` as so:
-
-```
-[deavmi.home.network]
-  # Required network information
-  Prefix="fdd2:cbf2:61bd::/48"
-  PublicKey=""
-
-  # For network connectivity tests
-  RouterIP="fdd2:cbf2:61bd::1"
-  NonRouterIP="fdd2:cbf2:61bd::2"
-
-[deavmi.community.network1]
-  # Required network information
-  Prefix="fd08:8441:e254::/48"
-  PublicKey=""
-
-  # For network connectivity tests
-  RouterIP="fd08:8441:e254::1"
-  NonRouterIP="fd08:8441:e254::2"
-```
-
-### Services
-
-All network services are declared within `deavmi/services` (file) like so:
-
-```
-[Web server]
-  address="fdd2:cbf2:61bd::2"
-  port=80
-[Babel web]
-  address="fdd2:cbf2:61bd::2"
-  port=4444
-```
+You can generate your ULA you would like to use for CRXN using a tool such as [Unique Local IPv6 Generator](https://www.unique-local-ipv6.com/) or if you are good at basic programming and mathematics you could write a C program to do it.
