Yes. Just be aware that you will now generate one new DNS query FOR EACH AND EVERY httpd request you receive. If you have a fair amount of traffic, you will generate a lot of new DNS traffic. This can cause additional load on your server, and will use up some additional bandwidth.
Normally it's not something to be alarmed about, but just know that there is no free lunch. Along with the benefits come some costs. Also, the benefit is not that great since most people come in from dial-up lines labeled ip045-183.ispdomain.com (which is not that useful anyway).
