Re: ISP customer assignments

[Nathan Ward <nanog () daork net>]

Ok, I've decided to do this a different way to my usual ranting.  
Instead of explaining the options over and over and hoping people can  
make sense of the complexities of it, become experts, and make good  
informed decisions, I've made a flow chart. Feel free to ask about  
details and I can get in to the ranting part, this is really a place  
to start.

Right now it assumes people only provide DSL or other dynamic sort of  
services.
It also assumes DS-Lite people are insane, so probably need better  
language there.
Also the first question is not necessarily about who you are, but who  
is driving the IPv6 'build' - which is why native, 6rd and ds-lite are  
not appropriate for the customer-driven side. I hope that makes sense.
No talk about ISATAP and stuff for inside the customer network either.  
And before you ask no ISATAP is not appropriate for ISPs, doesn't work  
through NAT.

Anyway:
- 6RD is used by free.fr. Not widely implemented by anyone yet.
- DS-Lite is something some guys at Comcast and others are talking  
about. Not widely implemented by anyone yet.
- The rest you can figure out from wikipedia and stuff.

Please email me with any corrections, complaints, or threats if you're  
a DS-Lite fan. I'll always keep old versions in this directory, and  
the latest version will always have this filename, so please link to  
it instead of copying it, etc. etc.:
