IPFS peers, finding CIDs etc

Hey guys, I was just playing around with IPFS and have it set up with some files, and have confirmed that my CIDs are working via shared links anywhere in the world, and that is awesome!

My primary question is how to find other CIDs hosted by peers. I’m connecting to several peers using the interface and bootstrap address (eg:
/dnsaddr/bootstrap.libp2p.io/p2p/QmeYHKeYvPDSfuN9T9PvXzi7L6EdK2aQbmwerw3Ae8T7JM), however when I go to browse ‘QmeYHKeYvPDSfuN9T9PvXzi7L6EdK2aQbmwerw3Ae8T7JM’ I get a 404 error, and if I try to inspect I just get a little endless triangle gif that fails to load anything.

Should I be able to access context peers have on IPFS by querying the Peer ID’s in the QmHash/bafyHash search window?

Is there any other way to find other CIDs peers have on IPFS? I’m not finding a great repository of such online which makes me think there must be a way via current peer connections…

Thanks for any advice,
c
