OK, so each device that needs internet access will need/have a separate unique public address? I guess we'll get a block of these from our ISPs?
Probably at a cost. I don't know of any business now a days that doesn't charge extra for every little thing.
I have a /56 subnet that costs me absolutely nothing. According to specs, ISPs are supposed to provide a /64 subnet, at a minimum. That's the entire IPv4 address space squared! Some IPv6 tunnel brokers provide, again at no charge, /48 subnets. That's a trillion, trillion addresses per subnet. IPv6 addresses are so plentiful there's no point in trying to charge for them. One comparison I recently read was if all the IPv4 addresses were represented by a 1.5" square, then IPv6 addresses would be represented by the area of the entire solar system! I've also heard, as another example, more IPv6 addresses than there are grains of sand on the earth or atoms in a ton of carbon. In short, there's a *LOT* of 'em. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
