What the DHT does
DHT stands for Distributed Hash Table. In IPFS, DHT-style routing helps clients find provider records for content-addressed data.
For a CID availability check, the important question is whether routing systems can find peers that claim to provide the requested content.
Why lookup results vary
DHT and delegated routing results can vary because provider announcements expire, peers go offline, and routing indexes update over time.
HiDHT treats provider discovery as a current network signal rather than a permanent guarantee.
