 ## Public
 
 A _public_ node is used as a fallback for gateway functionality when an external node is offline or an embedded node is used. It does not expose the API port. This type of node is not included as an option in Companion's preferences.

 IPFS Companion detects and tests requests for IPFS-like paths, such as `/ipfs/{cid}` or `/ipns/{peerid_or_host-with-dnslink}`, on any website. If a path is a valid IPFS address, it is redirected to load from your local gateway, which converts data from one protocol to another. The gateway at `localhost` will also automatically switch to a subdomain to provide a unique origin for each website. Providing a unique origin accommodates operations that are restricted to content that shares the same protocol, domain, and port, also known as [same-origin content](https://en.wikipedia.org/wiki/Same-origin_policy#:~:text=In%20computing%2C%20the%20same%2Dorigin,pages%20have%20the%20same%20origin).

 ### Detect DNSLink-enabled URLs
 
 IPFS Companion detects DNSLink info in the DNS records of websites. DNSLink is a simple protocol that links content and serviceability from DNS and leverages the DNS distributed architecture. See [Glossary > DNSLink](../concepts/glossary.md#dnslink). If a site uses DNSLink, IPFS Companion redirects the HTTP request to your local gateway:
