I agree with some people there to say that a person don't have to put DNS records of all IP he/she has. The IPs has already been signed but don't have to be resolved. Some might have an interest to protect the information of an IP he/she has. I saw a network which route the IP inside their internal network a bit dynamicly. And for a special purpose, it's open only for a certain time.
