| 1. Your university has a /48.
| 2. Your home gets a /48.
| 3. If your university provides you address space that you use in your
| home setup, that part is a university subnet.
The question is who otherwise provides the address space? And then
what address space I provide to those who connect to my house, and what
address space they provide others who connect to them.
Please do remember that while multiple layers of connectivity today might
be silly, as much of it is implemented out of ancient slow technology, there's
no reason this has to continue into the future - we should certainly be
planning for everyone to have high bandwidth low delay paths available.
In that environment, there's a strong incentive for multiple orgs/people
to group together, and between them buy a bigger pipe, as bandwidth costs
are almost never linear.
So, if ...
| What I think the setup should be is:
| 1. get a /48 for your home. Subnet at will.
who issus that /48? The university's ISP isn't going to, they've never
heard of me. APNIC? For every house in the AP region? And if they do,
this will actually result in scalable routing? More likely, the university,
that's where the connectivity goes - they're the ones who know who I am.
And in that case, they're not going to be providing any /48's to me.
If I'm going to get a /48 from somewhere, where would that be - without
requiring me to abandon my nice employer sponsored connectivity (which I
do use mostly for work related purposes) and go talk to some ISP with a
/35 or something to carve up.
| Our opinions are based for part on our respectives experiences.
| Please allow me to share part of mine:
I'm still waiting to hear about the global hierarchically routed Novell
net which actually worked with its address plan, and how big that was.
For sure, simple is better, but it has to actually work.
| - I teach IP (v4 and v6). You would be surprised to know how many
| students never grasp the VLSM concept.
Many students never grasp almost any concept that one cares to name.
Fortunately here, your average person doesn't have to grasp VLSM, all
they need to deal with is "here is your prefix, it is N bits long, put
those values in the config box where it asks".
Even better if one day (ideally soon) they don't even need to see that,
and just by connecting their box gets told the prefix to use.
