    Have you considered using powerdns www.powerdns.com. It uses MySQL for a
    backend, so there are no config files to maintain, and you can easily
    replicate the database to distribute the load.

    I can't yet testify to its ability to withstand a heavy loads, because I
    have not put it in production. So far in my testing, it is working
    flawlessly.
