Comment on Phones have unique phone numbers, why dont computers have unique computer-numbers?
adespoton@lemmy.ca 7 months agoAll you have to do is buy your own IP, and you can use it whenever you want. You don’t have to use one given to you by the upstream gateway via DHCP or BootP.
Of course, you need to make sure the upstream router is configured to not drop addresses it didn’t assign itself.

Even paying for a static IP its not like a phone number which is discoverable behind a NAT without extra router configuration.

Have you ever tried roaming with a cellphone…?
jeffhykin@lemm.ee 7 months ago
Yep, and I can verify my phone number didnt change when roaming, people could still call me.

Usually the phone number changes though. My phone number is 070Xxxx… here in Sweden, but my folks in law need to call 004670xxxx to call me unless they are visiting in which case 070xx works again

Your roaming is the extra configuration you speak of, and is usually an extra fee……

That’s like saying “why isn’t my phone number that I set up on my own POTS network usable on the international telephone system?”
If you’re behind NAT, you aren’t technically on the Internet; that’s why you need Network Address Translation in the first place.
IPv6 fixes this by letting every conceivable device have its own address on the Internet, but that comes with its own security and privacy issues, so it’s rarely used.
