 ### Checking providers
 
-When requesting content with Kubo, nodes search the DHT for 'provider records' to see who has what content. Let's manually do that on `node b` to make sure that `node b` is able to determine that `node a` has the data. Run `ipfs dht findprovs <hash>`. We expect to see the peer ID of `node a` printed out. If this command returns nothing (or returns IDs that are not `node a`), then no record of A having the data exists on the network. This can happen if the data is added while `node a` does not have a daemon running. If this happens, you can run `ipfs dht provide <hash>` on `node a` to announce to the network that you have that hash. Then if you restart the `ipfs get` command, `node b` should now be able to tell that `node a` has the content it wants. If `node a`'s peer ID showed up in the initial `findprovs` call or manually providing the hash didn't resolve the problem, then it's likely that `node b` is unable to make a connection to `node a`.

 ### Checking addresses
 
-In the case where `node b` simply cannot form a connection to `node a`, despite knowing that it needs to, the likely culprit is a bad NAT. When `node b` learns that it needs to connect to `node a`, it checks the DHT for addresses for `node a`, and then starts trying to connect to them. We can check those addresses by running `ipfs dht findpeer <node a peerID>` on `node b`. This command should return a list of addresses for `node a`. If it doesn't return any addresses, then you should try running the manual providing command from the previous steps. Example output of addresses might look something like this:
