I'm not the person you replied to, but I'll answer anyway :)

IPNS is essentially DNS over the IPFS network. IPNS domains point to a specific IPFS file (or a set of files, like we see here). IPNS domains are signed with a private key; when you want to update your IPNS entry, you add your new content to a new IPFS file and then you update the IPNS entry by signing it with a public key.
