Editor's Notes
- #3: INTENT: Give the audience (enterprise IT, ISP product managers, ISP strategy) a high-level understanding of where Recursive DNS fits in the overall DNS ecosystem. This sets the stage for the next slide. The user types “www.bestdomainnameever.com” into browser. Browser sends query to the Recursive resolver (ISP). Recursive knows which other servers it needs to ask in order to answer query “What is the IP address of www.bestdomainnameever.com?” Recursive talks to the Root, asks for information about .com Root knows DNS information about TLDs TLD Name Server stores the information for Second Level Domains (bestdomainnameever) under the TLD. TLD Name Server answers with IP address for tne Domain’s Name Server Recursive then sends the query to the Domain’s Name Server Name Server knows the IP address for the full domain (www.bestdomainnameever.com) Returns answer to Recursive server Recursive tells the browser the IP address and the browser retrieves content for user.
- #4: INTENT: These are the four positions that the product is built upon. Performance is not mentioned here because, although the service performs at a commensurate level to the competition, it doesn’t matter how well it performs if it isn’t stable and secure (hence available). Copy can be edited down to key words/elements.
