In IPv4 we normally design our subnets (with direct relationship to Vlan for ease of use as well) to 255 hosts using a /24 subnet mask. i.e. 10.10.10.0/24 is Vlan 10 with 10.10.10.1 being the default gateway.
In IPv6 what is the thought process of creating “subnet” on a LAN and VLans? I know there is no broadcast issue but what is the thought process on design? Do we have to throw out the old way of thinking when we design IPv6 LANs?
Any and all thoughts on this would be greatly appreciated, as maybe I am over thinking this or just need to mock up a do more detailed test and design with IPv6. But all the talk about IPv6 and auto-configuration and letting the router and hosts auto-config is making me think way too much.
