Does Freenet have decentralized domain names or DNS?
Not currently, and mostly on purpose. Domain names do three different jobs: identification, human-readable naming, and discovery. We think DNS is the wrong fit for all three on a decentralized network.
So Freenet has no direct equivalent of decentralized domain names, because we don’t think DNS is the right tool for either identification or discovery.
