IPv6 Software updating....
I'm just now learning about the new internet IPv6 protocal and frankly it's about as clear as mud... Perhaps I can impose on the more familiar here to give me some nice clear answers.
1) Is IPv6 one continuous address space?
I've seen articles where there is discussion about IPv6 like it's just one big 128 bit number, but other articles (some newer, some older) represent it as 2 64 bit numbers one to identify the network and another to specify hosts.
2) How will home networking routers and WIFI handle IPv6?
The discussion I've seen on these points is *so horridly muddled* that frankly I can make no sense of it at all. I get the NAT and UPNP stuff currently used, but apparently this is toast under the new scheme.
3) If I build an IPv6 LAN application, how do I isolate it's server from the open Internet?
From all reports IPv6 does not use NAT or conventional routing techniques that I understand, so a major concern is that an in-house network is NOT exposed to the internet.
4) Will local IPv4 be possible when IPv6 takes over?
This relates to question 3... I cannot find information anywhere as to whether I can still use IPv4 addressing on an IPv6 LAN setup.
