How to reverse DNS lookup for all related domain name and alias?

I am looking for a Unix/Linux command or a script to reverse DNS lookup for all related domain name and its alias for an IP address.

For example, domain name: "www.hp.com" points to IP: 10.10.100.100, and "www" has several alias pointing to the same IP address, like "aaa.hp.com", "bbb.hp.com" and even "ccc.hhpp.com".
If all these alias are in one DNS database, how can I find out ALL these domain names from the single IP address.
That is, from "10.10.100.100" to all:
www.hp.com
aaa.hp.com
bbb.hp.com
ccc.hhpp.com

Can "dig" do this?

Thanks a lot!
