 The InterPlanetary Name System (IPNS) is a system for creating such mutable pointers to CIDs known as **names** or **IPNS names**. IPNS names can be thought of as links that can be updated over time, while retaining the verifiability of content addressing.
 
+By analogy, IPNS names are like tags in git, which can be updated over time, and CIDs are like commit hashes in Git, which point to a snapshot of the files in the repository.

 ::: callout
 An IPNS name can point to any arbitrary content path (`/ipfs/` or `/ipns/`), *including another IPNS name or DNSLink path*. However, it most commonly points to a fully resolved and immutable path, i.e. `/ipfs/[CID]`.

-Due to the ephemeral nature of the DHT, peers forget records after 24 hours. This applies to any record in the DHT, irrespective of the `validity` (also referred to as `lifetime`) field in the IPNS record.
+Due to the ephemeral nature of the DHT, records expire [after 48 hours](https://github.com/libp2p/specs/tree/b5f7fce29b32d4c7d0efe37b019936a11e5db872/kad-dht#content-provider-advertisement-and-discovery). This applies to any record in the DHT, irrespective of the `validity` (also referred to as `lifetime`) field in the IPNS record.
 
 Therefore, IPNS records need to be regularly (re-)published to the DHT. Moreover, publishing to the DHT at regular intervals ensures that the IPNS name can be resolved even when there's high node churn (nodes coming and going.)

 #### IPNS record validity
 
-When setting the `validity` (referred to as [`lifetime` by Kubo](https://github.com/ipfs/kubo/blob/master/docs/config.md#ipnsrecordlifetime)) field of an IPNS record, you typically need to choose whether you favor **consistency** (short validity period, e.g. 24 hours) or **availability** (long validity period, e.g. 1 month), due to the inherent trade-off between the two.

 ### No providers returned
 
-If no providers are returned, the issue may lie in the content publishing lifecycle, specifically _reprovider runs_, the continuous process in which a node advertises provider records. _Provider records_ are mappings of CIDs to network addresses, and have an expiration time of 24 hours, which accounts for provider churn. Generally speaking, as more files are added to an IPFS node, the longer reprovide runs take. When a reprovide run takes longer than 24 hours (the expiration time for provider records), CIDs will no longer be discoverable.

    - **Enable the [Accelerated DHT Client](https://github.com/ipfs/go-ipfs/blob/master/docs/experimental-features.md#accelerated-dht-client) in Kubo**. This configuration improves content publishing times significantly by maintaining more connections to peers and a larger routing table and batching advertising of provider records. However, this performance boost comes at the cost of increased resource consumption.
 
    - **Change the reprovider strategy from `all` to either `pinned` or `roots`.** In both cases, only provider records for explicitly pinned content are advertised. Differences and tradeoffs are noted below:
       - The `pinned` strategy will advertise both the root CIDs and child block CIDs (the entire DAG) of explicitly pinned content.
       - The `roots` strategy will only advertise the root CIDs of pinned content, reducing the total number of provides in each run. This strategy is the most efficient, but should be done with caution, as it will limit discoverability only to root CIDs. In other words, if you are adding folders of files to an IPFS node, only the CID for the pinned folder will be advertised. All the blocks will still be retrievable with Bitswap once a connection to the node is established.
