# Content Hash Overview

The content hash is the ENS record that links your name to your website's content. These pages explain the concepts behind it:

* [Understanding Content Hashes, IPNS, and IPFS for ENS](/documentation/beginner/configuring-your-ens-name/content-hash-overview/understanding-content-hashes-ipns-and-ipfs-for-ens.md) — how the three fit together and when to use IPFS vs IPNS
* [Understanding IPFS Content Identifiers (CIDs)](/documentation/beginner/configuring-your-ens-name/content-hash-overview/understanding-ipfs-content-identifiers-cids.md) — CIDv0 vs CIDv1, and why your CID looks different after saving

For the full list of supported content hash protocols and their encodings, see [Record Types](/documentation/advanced/record-types.md).
