[HamWAN PSDR] IP space plan

[Bart Kus]

I've thought about this quite a bit over the last few months.  I'd like 
us to take a multi-net approach here.  I think HamWAN is the exact kind 
of network that Net-44 aims to please, so I'd like to deploy Net-44 
subnets here. This will allow easy peering with ISPs once HamWAN gets an 
Autonomous System Number (ASN).  However, IPv4 address space may be an 
issue, if not for technical than possibly for political reasons.  So use 
of Net-44 space may be limited to the most public endpoints of 
communication.  Only experience will tell.

To mitigate the risks of Net-44 use, I think it makes sense for HamWAN 
to register (a) public IPv6 block(s).  There ought to be plenty of these 
around, and it'd be good to avoid NAT where possible.  Just one of these 
IPv6 /64 networks should be enough for all foreseeable purposes.  The 
tricky part is it may be impossible to get a block without an ASN.  And 
it's impossible to get an ASN without existing multi-homed ISP 
contracts.  Correct me if I'm wrong here. Relevant doc 
<http://www.apnic.net/__data/assets/pdf_file/0009/23994/how-to-get-initial-ipv6-block.pdf>.  
Have not read it all yet, feel free to decode.  :)

Which leaves us with the old private IP space.  The problem of using 
this is possible collisions with private IP space used by individuals' 
home networks.  This can be mitigated by using private IPv6 space, which 
very few people will be using on their home networks right now.  But I 
suspect that situation will change as time passes and we'll once again 
be in trouble.

One last consideration is network device compatibility.  Does your VoIP 
device have IPv6?  How about your (possibly old) home router?  Net-44 
makes a lot of sense in these scenarios.  What about the devices trying 
to access HamWAN's resources from the outside world?  Does your ISP 
allow you to route to an IPv6 HamWAN address?  Asking people to dial 
into IPv6 tunnelling services is a further barrier to entry.

So to wrap it up, I'd like HamWAN to register for a fairly big chunk of 
Net-44 (/20?), register at least one IPv6 block, and get an ASN.  From 
there we'll have the resources to conduct subnet allocation to users & 
infrastructure without worrying about collisions.  But in the immediate 
term, we'll likely end up using private space.  :-/
