DNS 3 and 4 = redundancy?

If I were to have two hosting accounts with two different providers and had the name servers like so:

DNS1: Host 1
DNS2: Host 1
DNS3: Host 2
DNS4: Host 2

Would this add any redundancy to my site? Would this help prevent it from becoming overloaded?

Two DNS servers on the same server is redundant. All you really need is DNS1 on Host1 and DNS2 on Host2. However, you should probably have a 2nd DNS server on each machine that is only available to localhost that does the lookups for sites that you do not run DNS for. The actual public name servers should not do lookups for sites you do not run (for bind set recursion no and fetch-glue no).
