IPv6 Address Assignment Example

Sometimes it’s difficult to disengage from the subnetting mentality of IPv4 whose goal was to conserve addresses. Here we don’t need to do that, and this is actually one of the things that simplifies IPv6 compared to IPv4, even though it may not seem simpler at first glance.

This is a great piece of information Laz. Thanks for sharing. I don’t think I’d ever have considered that any aspect of ipv6 could be simple in comparison to ipv4!

The numbers involved when allocating ipv6 subnets are astounding and my ipv4 mindset can not help but panic when we talk about 2^64 host addresses on a point to point link!!!

One question on the /80… if we implemented this how would an interface assign it’s 48 host bits in the case of a SLAAC assigned Global Unicast address?
