That's a nice way of saying you did not understand 99% of the reply.

zen.spamhaus.org provides a service that depends the DNS client IP
address. Low-volume DNS clients get free service, but high-volume
DNS clients have to pay for a subscription.
For example, if you use the resolver at a big ISP, or a public
service like 8.8.8.8 or 4.4.4.4, then zen.spamhaus.org won't work
well for you, if at all.
