So many questions and so few answers.


It's funny how almost all network people I run into that seem to know what they are talking about get a blank look on their face when I mention this subject. Despite the fate that it is staring them right in the face when they run an ipconfig on a modern OS.

Anyway, does anyone know enough about this subject to address some basic questions I have?


1. Am I correct in assuming that stateless auto configuration produces its hex IP address by calculating the Routers MAC with the MAC of the local NIC?

2. DHCPv6 an alternative to stateless autoconfig. Am I correct in assuming you can get a block of addressses from your local ISP and configure your DHCP server to hand them out?

3 are subnetting and NATing a thing of the past?

Some general info would be good as well.

for instance I believe fe80 is termed a global IP address.

What the hell is link local and site local?

Ans3. No, subnetting and NAT are not outdated concepts.

They are still used by switches and bridges. In fact I have seen NATed address of my laptop in LAN using ipconfig and my real static IP when I port forwarded my laptop for WorldWideWeb. I mean when I saw it from my friends computer with different ISP it was x.y.z.w but my local ip what I saw using ipconfig was something like 192.168.1.something

This is where subnetting and NAT is working at my place.

I assumed IPv6 did away with subnetting and NATing. I'm interested if anyone has a general understanding of IPv6.
