According to my experience, less restriction is imposed by TLD operator because TLD servers have sufficient ability and it is not secure for their service to limit, especially when too much limitations are added.

Subject: querying TLD nameservers - limitations
I am developing a monitoring script for internal use and this requires extensive querying of TLD nameservers (a .. m).tld servers.
1. Are there any rate limitations imposed by TLD servers i.e these servers allows only certain number of DNS queries per IP per second?
2. Are there other limitations I should be aware of while developing my script?
Any experience among this group members in developing these kind of scripts using Net::DNS::Resolver perl module?
