Dns Server Request Throttling

Hi,
I have an application which processes many dns lookup requests at quite a
pace although this is spread over many dns servers.
I know that dns servers in general will throttle requests from unique ip
addresses in order to counter denial of service attacks.
I would like to know what guidelines I should follow to make sure that I'm
not mistakenly identified as a DoS attack; i.e. is there some number of
requests within a certain time period that I must stay below?, is this
variable and if so can I query the server to get this value?
Are there any guidelines in general as to how many requests I should be
making within a particular time period irrespective of whether a server
blocks at some other threshold?

Many thanks,
N

No one can say for sure, but you might do better in
one of the BIND developer or other network developer
groups.
