Please take a look at this Cisco document regarding
Scaling DNS services and CSM:

It a while since I had such a good laugh.
The cisco doc above requires more than one device, but as IOS is
incapable of running BIND they have come up with their kludge.
p.s.- long ago read DNS & BIND but this book assumes
tolerance to DNS timeouts and availability of more
than two DNS IP addresses. :)
If you are CARPing, you have more than 1 box, so you can put caching
resolvers on them, or other boxes.
If you are serving zones, use a hidden master and have slaves pull from
that to serve to the Internet.
You are wasting your time trying to load balance DNS with hardware or
software when the protocol was designed to withstand major problems.
If your leased line your cisco/carp boxes goes down to then what?
DNS is designed to be globally redundant, with multiple servers serving
the same zones. Work with it, not against it.
