Caching DNS Server Configuration | Linux DNS Server | Part4

Caching DNS Server Configuration is demonstrated in this video. I've gone through every component of the Caching-Only DNS Server Configuration and Setup. Read the Detailed Guide: https://mailserverguru.com/linux-dns-server DNS servers are divided into three categories: primary, secondary, and caching-only. In this video, we'll look at how to configure caching DNS servers. The default mode for the Linux DNS Server is caching DNS. The DNS Service on the System will operate as a caching DNS Server if we simply start it. When we don't require the DNS server to host any authoritative zones, we can set it up as Caching-Only DNS. We can set up a Caching DNS Server if we only need a DNS Server for name resolution. The caching DNS Server will receive any query from clients and will cache the result on the DNS cache, and it always replies from the cache. All DNS Servers reply from the cache by default, however caching DNS is exclusive for this reason. When the DNS cache expires, we must flush the cache to reflect the most recent DNS record modifications. Otherwise, the DNS cache will return obsolete values. Caching-Only DNS can be configured as a Forwarding DNS also, in which case it will accept client DNS queries and, rather than travelling to the internet for name resolution, will forward the queries to the Upstream DNS Server. However, the primary goal of caching will remain the same. #dnsserver #binddns #linuxdns Chapters: 00:00 Caching DNS Server Introduction and Design. 01:08 Caching DNS Server Configurations 07:50 DNS Cache Testing & Cache Flush 🔔 𝗩𝗶𝘀𝗶𝘁 𝗟𝗶𝗻𝘂𝘅 𝗗𝗡𝗦 𝗦𝗲𝗿𝘃𝗲𝗿 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻 𝗣𝗹𝗮𝘆𝗹𝗶𝘀𝘁: 👉 https://www.youtube.com/playlist?list=PL291a0KYQZSK6E_1j9xkkieCOi_867pyc 🔔 𝗟𝗶𝗻𝘂𝘅 𝗗𝗡𝗦 𝗦𝗲𝗿𝘃𝗲𝗿 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻𝘀 Install and Configure Linux DNS Server: 👉 https://youtu.be/FeZjRF-aVlc Primary DNS Or Master DNS Server Configuration: 👉 https://youtu.be/fb41xuax8xU Secondary DNS Or Slave DNS Server Configuration: 👉 https://youtu.be/jygerYi-Ytk Caching DNS Server Configuration: 👉 https://youtu.be/y_PUUwY0vwc DNS Forwarder Configuration with Caching DNS: 👉 https://youtu.be/nDJ8WsXYtMs Forward Zone Configuration For DNS Forward Lookup: 👉 https://youtu.be/4ghXAJvI-t4 Reverse DNS Configuration For DNS Reverse Lookup: 👉 https://youtu.be/ButSB33dXtA DNS Records A, PTR, CNAME, NS, MX, SOA, TXT: 👉 https://youtu.be/tpQReHosCD4 🔔 If you want to learn more about DNS Server Configurations Please visit the website: 👉 http://www.mailserverguru.com 🔔 Please Subscribe to my Channel, to get my latest videos: 👉 https://www.youtube.com/mailserverguru?sub_confirmation=1 ★☆★ CONNECT ON SOCIAL MEDIA ★☆★ 👉 𝗟𝗶𝗻𝗸𝗲𝗱𝗜𝗻: https://www.linkedin.com/in/munnavai 👉 𝗙𝗮𝗰𝗲𝗯𝗼𝗼𝗸: http://www.facebook.com/mailserverguru 👉 𝗧𝘄𝗶𝘁𝘁𝗲𝗿: http://www.twitter.com/mailserverguru 𝗔𝘂𝘁𝗵𝗼𝗿: 𝗠.𝗠.𝗥𝗮𝗵𝗺𝗮𝗻 𝗠𝘂𝗻𝗻𝗮 || 𝗺𝘂𝗻𝗻𝗮𝘃𝗮𝗶@𝗴𝗺𝗮𝗶𝗹.𝗰𝗼𝗺 || 𝟴𝟴𝟬𝟭𝟵𝟭𝟮𝟬𝟲𝟰𝟰𝟴𝟯
