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
What makes you think all phones have unique numbers? Some have no direct dial numbers.
As for each device getting a unique IP address this is somewhat in the spec for EUI-64 IPv6 address. Your IP is based on your interfaces MAC address but this becomes a privacy nightmare.
If the MAC address's of the wifi chip in your phone is 1122.3344.5566 your IPv6 address at home can be 2001:0db8:0000:00000:1122:33ff:fe44:5566 but when at work your address may be 2001:db8:1000:0000:1122:33ff:fe44:5566. No matter where you connect to the last 4 sections of the address is the same and companies will use that as one of the data points of your digital profile.
I meant "in the same way that phone numbers are unique to phones (not perfectly unique, some phones have dual Sim, some have no sim, sometimes a Sim changes numbers after contacting the provider, etc)"
Its just typing all that^ in a title is kinda long.
EUI-64 IPv6 (and why its not a reality) though is kinda what I'm curious about. But not really because, even under that spec, its still not static like a phone number. I want to know why networks were not created in a way where I can send a message to a laptop regardless of what WiFi its connected to (assuming it is connected and online).
Because it will be an ungodly thing to manage. The national phone databases are already a nightmare to manage. it would be far worse if we had a global one.
The IMEI is unique
