Why doesn’t every computer have 256 char domain name, along with a private key to prove it is the sole owner of the address?
Edits: For those technically inclined: Stuff like DHCP seems unnecessary if every device has a serial number based address that’s known not to collide. It seems way more simple and faster than leasing dynamic addresses. On top of that with VOIP I can get phone calls even without cell service, even behind a NAT. Why is the network designed in such a way where that is possible, but I can’t buy a static address that will persist across networks endpoint changes (e.g. laptop connecting to a new unconfigured wifi connection) such that I can initiate a connection to my laptop while it is behind a NAT.
- Yes, it would be a privacy nightmare, I want to know why it didnt turn out that way
- When I say phone number, I mean including area/country code
- AFAIK IP addresses (even static public ones) are not equivlent to phone numbers. I don’t get a new phone number every time I connect to a new cell tower. Even if a static IP is assigned to a device, my understanding is that connecting the device to a new uncontrolled WiFi, especially a router with a NAT, will make it so that people who try to connect to the static IP will simply fail.
- No, MAC addresses are not equivalent phone numbers. 1. Phone numbers have one unique owner, MAC addresses can have many owners because they can be changed at any time to any thing on most laptops. 2. A message can’t be sent directly to a MAC address in the same way as a phone number
- Yes, IMEI is unique, but my laptop doesn’t have one and even if it did its not the same as an eSim or sim card. We can send a message to an activated Sim, we can’t send a message to an IMEI or serial number
AFAIK static public-facing IP addresses are limited to a physical location. It would work if my laptop never left my house but as soon as I take it to the airport its no longer accessible. People who try to connect to the static ip would just get a message saying the address timed out.
I’ve got a VPN set up on my home server so when I leave the house, my public IP is still the same on my laptop as it is at home. If you’ve got people sending you messages directly via IP why wouldn’t you just set that up?
Thats a valid solution, thanks for saying it!
I think it is good to note this requires either having another system at home or in the cloud to host the VPN right?
Not actually! I mean, yes, you’d need another device, but your router itself can be the VPN host if it’s the right model. The VPN server software is extremely lightweight, so most higher end routers just include it as an option in management, but you can get away with a cheap router and something like a cheap raspberry pi/clone, which would also give you something to put pihole on
