Ok .. lots of folks here can probably help but you’ll need to be a bit more 
specific :)

Advise on planning for it?  Implementing it on specific gear?  last mile to 
customer? … over entire deployment?

Here’s some info that may help (from network perspective):

Full dual stack deployment across network with Juniper MX throughout
/126 for point to point
/128 for loopback
OSPFv3 for connected networks and loopbacks
iBGP for full internal and external routes (where needed)

For DSL/Wireless (PPPOE):
/40 and /47 IP pools per device that is serving customers (varies with number 
of customers per device)
Customers receive /64 allocation via DHCP-PD over their existing PPPOE 
connection

For Cable (DHCP):
/48 and /56 IP pools per geographic region that is serving customers
Customers receive /64 allocation via DHCP-PD

For fiber (static or BGP)
/126 point to point
/64 allocation by default, /56 upon request, larger if justified


I’ve pretty much followed this model in one form or other since 2008 when I did 
the first network end to end
