 While having peers that cannot talk to each other may sound like an oddity, two prevalent causes of unreachability are network address translators (NATs) and firewalls. Having asymmetrical networks where peers `X`, `Y`, and `Z` can connect to `A`, but `A` cannot connect to them is fairly common. Similarly, it is _extremely_ common that peers `A` and `B`, which are both behind NATs, cannot talk to each other. To deal with this, IPFS nodes ignore other nodes assumed to be unreachable by the general public. Nodes also filter themselves out of the network if they suspect they are not reachable.
 
-To do this, we use [libp2p's AutoNAT](https://github.com/libp2p/go-libp2p-autonat), which acts as a distributed _session traversal utility for NAT_ (STUN) layer, informing peers of their observed addresses and whether or not they appear to be publicly dialable. Only when peers detect that they are publicly dialable do they switch from client mode (where they can query the DHT but not respond to queries) to server mode (where they can both query and respond to queries). Similarly, if a server discovers that it is no longer publicly dialable, it will switch back into client mode.

 IPFS exposes a _rate-limited_ AutoNAT service on all IPFS nodes that have discovered that they are publicly dialable. These requests are infrequent and do not have a noticeable overhead.

 When you add a _file_ to IPFS, it might be too big to fit in a single block, so it needs metadata to link all its blocks together. UnixFS is a [protocol-buffers](https://developers.google.com/protocol-buffers/)-based format for describing files, directories, and symlinks in IPFS. This data format is used to represent files and all their links and metadata in IPFS. UnixFS creates a block (or a tree of blocks) of linked objects.

 ### js-ipfs being discontinued
-Development of the [js-ipfs project](https://github.com/ipfs/js-ipfs) is being discontinued to focus on [Helia](https://github.com/ipfs/helia), a leaner, more modular, modern implementation of IPFS in JavaScript scheduled for release in 2023. To learn more about Helia and the current state of IPFS in JS, see the [blog post](https://blog.ipfs.tech/state-of-ipfs-in-js/).
