![]() ![]() ![]() ![]() I understand the concepts of ip address, routers, subnets, routes (between subnets), ports, and I'm beginning to understand bridges but I do not understand how the Internet is to work without a being behind a nat router.having not lived before NAT I do not understand why it is a hack.does an IPv6 Internet without NAT just mean that everybody gets an ip and there's no need for a NAT router in between with a single unifying ip address protecting all the machines on the network from being accessed? It sounds to me like instead of a single firewall on a single router, each machine will have to fend for itself with its' own firewall. I've been told that this was a hack simply because the Internet was running out of ipv4 addresses. Forgive me if this sounds a little amateurish, or if this is the wrong stackexchange, but.most of my entirely life I've had ipv4 behind a NAT router.
