IPV6 is sort of like the new MAC address hardware identifier. An IP for every atom in the universe!

- oldjavacoder 4y agoThat's the issue I have with it, it's not a feature.
- p1mrx 4y agoThere are a lot more atoms (10^80 or so) than IPv6 addresses (10^38). How could a device have a hardware-embedded IP address, if the hardware vendor doesn't know which ISP you will use?
- Dylan16807 4y ago> How could a device have a hardware-embedded IP address, if the hardware vendor doesn't know which ISP you will use? By putting the hardware part in the second half, and the ISP part in the first half. You know, like how it works by default.
- p1mrx 4y agoMost devices randomize the second half by default, using RFC3041 and its successors.
- Dylan16807 4y agoThey do, these days. But then why were you asking "how" a device could have a permanent hardware identifier with its address? Just don't implement those optional RFCs. And the comment you were replying to didn't say it had to be the entire address, and there's no reason for it to be.
