I have a /32 assigned from ARIN (2001:4918::/32)
I’m looking for some direction/reading list of how to properly
configure IPv6. I’ve read to use a /64 for PtP interfaces and I’ve
read use a /128 instead. Assign all loopbacks from the same /64,
use a different /64 for each loopback. Ect, ect.
I’m trying not to light a religious war but what is the current best
practice for IPv6 deployment in a service provider network?
PS. I’ll be at NANOG69 in DC next month, 1st NANOG for me after 22
years. ☺
At the start, the advice was to configure individual /64 for
loopbacks, however latterly its assign a /64 for loopbacks and configure
/128 instead.
Stick with a /48 for sites/customers.
The best advice is to use nibble boundaries (see:
https://www.ripe.net/manage-ips-and-asns/ipv6/ipv6-subnetting-card)
hence /52 /56 /60
I also recommend watching this (Tom Coffeen from Infoblox at UKNOF35
which covers this exact subject):

Its worth a watch and covers the basics
