I can do that in IPv4!" It is true that a lot of what we can do in v6 we can do in v4 as well. That's because v6 is based on v4 and needsen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.technet.com/ipv6/archive/2007/05/10/But-I-can-do-that-in-ipv4.aspx#940608Sat, 12 May 2007 13:39:22 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:940608jordi<p>One more example. I only have an IPv4 address in my ADSL and of course it is NATed. Paying for more is a huge cost. Instead, I use IPv6 and then I have a /48, which means 65.535 subnets of 2^64 each. Now I've in my home lots of IPv6 devices, such IPv6 cameras, and all kind of gadgets. I can control all my home automation remotelly, I can feed my pets, open the blinds to see them with the cameras, etc.</p> <p>It is true that I could do that with IPv4, but with a huge extra cost or writing an application that traverse the NAT; once more is a matter of cost.</p> <p>IPv6 brings simplicity back to the networks, and thus, makes things just work very inexpensively.</p>
