About DNS records...

I was wondering how does cloudflare can get your domains every sub domain and ip address associated with it Like you enter a domain and cloudflare fetches ever dns record set on the domain in a moment The NSLookup command only shows the ip of the specific domain that i entered it doesn't show sub domains unless I enter it HOW can I get info about a sites dns record the way that Cloudflare does it? And how can I prevent others from accessing it Since cloudflare can access it it means others can access it too I'd like to know the way to stop others from accessing it easily
