Tangential by related technical question:

Does something exist out there which is equivalent to a domain name for a website (or an any entity) which is independent of a external entities, like DNS or DNS like servers.

I know that in some sense public/private keys in asymmetric cryptography mimic that feature (the public key being the address of the receiver), but is there anything out of the box? Does Tor have a similar feature?

I do understand that this equivalent to which I'm alluding to, may be an unintelligible string of characters, unlike current website user friendly names. I also understand that the underlying ip address change can be a challenge , but probably not an insurmountable one.
