I have my primary DOMAIN through the Ethereum Name Service. I see documentation that shows you can set subdomains as I would like to do this for security for an up-coming ICO.
So I would like to register ICO.DOMAIN.eth to point to the contract for the ICO that way the address can't get changed on my site like has happened in the past. Plus it seems easier for ICO participants to enter the ICO.DOMAIN.eth.
Is there a way to do this? On the ENS site I see a mysterious section "CONTENT HASH FOR APPS (IPFS/SWARM)", is this where I register the ICO subdomain and if so how?
