LXer: Using IPv6 with Linux? You've likely been visited by Shodan and other scanners


Published at LXer:

One of the benefits of the next-generation Internet protocol known as IPv6 is the enhanced privacy it offers over its IPv4 predecessor. With a staggering 2128 (or about 3.4?1038) theoretical addresses available, its IP pool is immune to the types of systematic scans that criminal hackers and researchers routinely perform to locate vulnerable devices and networks with IPv4 addresses.

Enhanced privacy? Only if you never do anything on the internet, ever. If you do connect to the internet then, obviously, the actual address of your specific device (which will not change if you connect to the internet another way) is exposed.
Still, apparently NAT is "security through obscurity" and not needed for IP6...

Unless I misunderstood, the whole point of the article is that IPv6 is security through obscurity, which is no security. NAT is not security through obscurity, but apparently is only implemented for ipv4. The only thing probed with a ipv4 router is the router, because of NAT. Until firewalls are standard on IPv6 routers, I think it'd be madness to not use a IPv4 router.

I think there is a bit more too it than that but, yes, that's what I took from it also. Quite why somebody thought it would be a good idea to have a unique, globally accessible, IP address for every device in the world is beyond me. As you pint out NAT is not security through obscurity but does provide a certain amount of actual security.
