The CSM Tech organization has a substantial web presence with several publicly accessible web and application servers. You have DNS servers that handle Internet queries for all your publicly accessible resources. However, after doing some statistical analysis on your public DNS servers, you find that your servers are handling recursive lookups for clients that are not within your organization. Your public DNS servers should handle recursive queries only for your internal clients, but the servers should handle iterative (nonrecursive) queries from external sources. What do you recommend? What are the commands needed to implement the solution?
