- CSM Tech has a sizable web presence, with multiple publicly accessible web and application servers. All of your publicly available resources are served through DNS servers. However, after performing some data analysis on your public DNS servers, you discover that your servers are handling recursive lookups for customers outside of your business. Your public DNS servers should only accept recursive requests from internal clients, but iterative (nonrecursive) inquiries from external sources. What do you think? What commands are required to put the solution into action?You have the option of categorizing DNS records by category. Every single one of them has to be segmented into manageable pieces and accompanied with examples and arguments.
