I like this idea a lot more than needing name servers. But I can't tell if this is a solution or not.
This does not appear to complete with DNS.
This operates at the link layer and aims to provide a decentralized authentication mechanism for hosts and DoS prevention during address discovery.
afaict a scheme that operates somewhat like this could probably be developed as an alternative to certificate authorities. Key diagram of the protocol:

The concept of IPv6 Bitcoin-Certified Addresses aims to simplify the connection between Bitcoin nodes by using IPv6 addresses. This proposal aims to streamline the process, potentially eliminating the need for name servers in the Bitcoin network. However, the effectiveness and practicality of this approach require thorough analysis, testing, and community adoption to ascertain its viability as a solution for node connectivity and network management within the Bitcoin ecosystem.
