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
You seem to have be missing a fundamental thing about tech but I can't pin down what it is. So I will respond to your edits.
You can. It's called Provider Independent Space and it a pain to go with as an individual.
Because people smarter than you, I, and everyone else in this post said 'Yes EUI-64 is a good idea in principe but the problems on a privacy perspective outweigh the advantages. So let's build a system called MAC randomisation so people can get multiple address to access the internet with. '
The good news is you can turn off MAC randomisation.
In some parts of the world or before 2000 if you changed mobile providers, say from Vodafone to Telstra you had to get a new number. Since that change number routing has become a nightmare and it makes the BGPv4 table look sane in comparison.
This is a complex one due to NAT in the ipv4 space. NAT exists purely to allow devices to have the same private IPv4 address and hide behind a public v4 address.
If your laptop has a regular Sim slot it will have an IMEI. True we can't send messages via IMEI or serial because those systems were never designed for message routing.
