IPFS allows you to request data from any IPFS node with a copy using the data's CID or content identifier. This process usually involves a lookup on the distributed hash table and may also require establishing new connections to the nodes storing the content.
If you're running an IPFS node that serves many requests, like a public HTTP gateway, for example, you may be able to speed up queries by maintaining long-lived connections to nodes that provide a large volume of data.
Prioritizing connections to certain peers is called Peering, and you can tell IPFS which peers to prioritize by editing the Peering configuration in your IPFS config file.
To peer with nodes from Cloudflare, you could update your config to include a Peering section like that consists of the ID and addresses for their node:
Generally speaking, users running IPFS at home won't need to set up peering and can ignore this page!
Peering is most helpful for nodes that have a lot of concurrent connections since it prevents the connection manager from dropping connections it thinks aren't "useful" any longer. If you find yourself running near the connection manager's limit, you may benefit from peering with content providers.
