Of course, I realize the need to go to IPv6 out on the open Internet since we are running out of addresses, but I really don't understand why there is any need to use it on an internal network. I have done zero with IPv6, so I also wonder: Won't modern firewalls do NAT between internal IPv4 addresses, and external IPv6 addresses?

I was just wondering since I have seen so many people struggling with IPv6 questions here, and wonder why bother?

This is a Canonical Question about IPv4 Subnets.

Related:

How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself.

  • If I have a network, how do I figure out how to split it up?
  • If I am given a netmask, how do I know what the network Range is for it?
  • Sometimes there is a slash followed by a number, what is that number?
  • Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different?
  • Someone mentioned something about knowing binary for this?
