QUESTION POSED ON: 22 September 2008
In IPv4 we normally design our subnets to 255 hosts using a /24 subnet mask (with a direct relationship to our VLAN for ease of use, as well). 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 subnets on a LAN and VLAN? 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 a mock-up to do a 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.
