+# Alanet, The **Ala**mode **Net**work
+
+[[_TOC_]]
+
+Alanet is a network that alamodians can connect to, host services on and experiment with.
+
+## Properties
+
+- _Address Space_: Alanet uses the address space `0200::/8` which was deprecated by [RFC4048](https://www.rfc-editor.org/rfc/rfc4048.html)
+  in December, 2004. It's still reserved by IETF, but I'm not super worried about that.
+  - All IPv6 addresses in Alanet start with the bytes `[0x00, 0x02]`.
+- _ASN Range_: In true ohea spirit, the ASN range is `42069XXXXX`. ASNs are numbers that identitify entities in Alanet 
+  and control allocated IPv6 _prefixes_. For example, `ASN4206900055` could control the prefix `23f::/16` and only 
+  they are allowed to advertise that prefix.
+
+## ASN Policy
+
+You can choose any ASN decimal number as long as its prefix is `42069XXXXX`.
+
+The first 10 ASNs are reserved: `4206900000 - 426900010`
+
+> A valid ASN could be `4206900055`.
+
+## IPv6 Address Allocation Policy
+
+All new members can choose any unallocated `200::/16`. After half of that address space has been allocated, then we will
+revisit this policy and most likely start allocating `/24` or `/32` prefixes. The maximum allocation is a `/8` and the 
+minimum allocation is a `/32`.
+
+- `200::/16` is reserved for special projects.
+- `2ff::/16` is reserved for future multicast work.
+
+> Choose any two hex digits X and Y and your assignment will be `2XY::/16`.
+
+# OHEANA
+
+OHEANA is the `OHEA Number Authority`. OHEANA keeps track of ASNs and IP addresses, and in the future, domain names and 
+special Alanet protocols.
+
+You will need to register with OHEANA your chosen ASN and prefix before joining and peering on the network.
+
+> Pronunciation is up to the reader.
+
+# Conclusion
+
+OHEANA has setup a git repo registry here: [https://git.ohea.xyz/OHEANA/registry](https://git.ohea.xyz/OHEANA/registry)
+
+Go and allocate your ASN and prefix! First come, first served!
