The contract is easily found under ipfsreg.eth. The public resolver only took namehashes, how I understood it, ipfsreg.eth uses a name, for example danakil (.eth), as input, and computes the namehash. The ipfsreg.eth contract defines "ipfs" within the setText field in the public resolver as where IPFS hashes are stored.

Why I created ipfsreg.eth

I patented a thesis I worked on for a year, using Ethereum, and put it under danakil.eth,

I wanted an easy way to search for it online, did not find that in the Ethereum Name Service, so, I put up ipfsreg.eth where I can type in "danakil" and get back the IPFS hash to my thesis.
