In the world of IPFS data is accessed, instead, by a Content ID ("CID") — a name that is derrived from, and unique to, the data it points to, rather than where it's located. The way this works is fairly technical, but the same data _always_ produces the same CID, and the CID unquely refers to that data[^1].
My site (as I write this) has the CID of `/ipfs/QmWSnMtmfh78EdKjztRMRLFufk4BMKN3nSvqZBR5g8aDWF`. You can see exactly it at [ipfs.io](https://ipfs.io/ipfs/QmWSnMtmfh78EdKjztRMRLFufk4BMKN3nSvqZBR5g8aDWF), at [Cloudflare](https://www.cloudflare-ipfs.com/ipfs/QmWSnMtmfh78EdKjztRMRLFufk4BMKN3nSvqZBR5g8aDWF), [dweb.link](https://dweb.link/ipfs/QmWSnMtmfh78EdKjztRMRLFufk4BMKN3nSvqZBR5g8aDWF) or any other IPFS server.
Another of my sites (a 3D model of my brain) has the CID `QmPgEidvA67eUxtSgLQy2N5cWXh8WQ8r7iYQn1ecjrL8Mz`. You can see it at [ipfs.io](https://ipfs.io/ipfs/QmPgEidvA67eUxtSgLQy2N5cWXh8WQ8r7iYQn1ecjrL8Mz), at [Cloudflare](https://www.cloudflare-ipfs.com/ipfs/QmPgEidvA67eUxtSgLQy2N5cWXh8WQ8r7iYQn1ecjrL8Mz), [dweb.link](https://dweb.link/ipfs/QmPgEidvA67eUxtSgLQy2N5cWXh8WQ8r7iYQn1ecjrL8Mz) or any other IPFS server, as I have it stored on an IPFS server connected to the internet.
This means that if Jo Bloggs makes a copy of my site ("pins" that CID), and then my site goes down forever, everyone can still view my site, _exactly_ as it was meant to be, by getting it from Jo Bloggs instead of me. I'm glossing over some details here but, broadly, so long as someone cares about the data in question: link rot defeated.
