DNS Records A, PTR, CNAME, NS, MX, SOA, TXT | Linux DNS Server | Part8

In this video, I go over the different DNS record types and how to use them with practical examples. I go over the most common DNS record types including A, PTR, CNAME, NS, MX, SOA, and TXT records. Read the Detailed Guide: https://mailserverguru.com/linux-dns-... A Record, A means address record. The forward zone file uses A record. A record associates a subdomain with a certain IP address. PTR record, found in the Reverse zone file. It's known as a reverse lookup, and it's most commonly used to verify the hostname of a mail server. If we search for a subdomain that is related to an IP, it will seek for the PTR record in the reverse zone and identify the IP associated with the subdomain. CNAME Record, CNAME stands for canonical name, and it is used to define each host record to point to the original A record if we wish to use the same server for different subdomains. This is referred to as aliasing. NS Record, NS records defines the Name Server or DNS server of the domain, if we want to know any domains DNS server, then we have to query the NS record. MX record, MX trans for mail exchanger, the domains mail server is specified by the MX record. MX record defined with its priority, if domains have multiple mail servers then we can set them with priority. SOA record, SOA trans for the start of authority. SOA contains administrative information about the zone, like responsible contact person for the zone, last update time, zone transfer timing to secondary DNS etc. TXT record, TXT records associates arbitrary text data with the zone, these records are for a special purpose, like for mail server security SPF, DKIM and DMARC records are provided in DNS as TXT record, sometimes special codes are provided as TXT record for domain verification by various organizations. #dnsserver #binddns #linuxdns Chapters: 00:00 DNS Records Introductions 01:00 A Record 03:10 PTR Record 05:14 CNAME Record 07:28 NS Record 08:54 MX Record 10:51 SOA Record 12:04 TXT Record 🔔 𝗩𝗶𝘀𝗶𝘁 𝗟𝗶𝗻𝘂𝘅 𝗗𝗡𝗦 𝗦𝗲𝗿𝘃𝗲𝗿 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻 𝗣𝗹𝗮𝘆𝗹𝗶𝘀𝘁: 👉    • Linux DNS Server   🔔 𝗟𝗶𝗻𝘂𝘅 𝗗𝗡𝗦 𝗦𝗲𝗿𝘃𝗲𝗿 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻𝘀 Install and Configure Linux DNS Server: 👉    • Install and Configure Linux DNS Server | L...   Primary DNS Or Master DNS Server Configuration: 👉    • Primary DNS Or Master DNS Server Configura...   Secondary DNS Or Slave DNS Server Configuration: 👉    • Secondary DNS Or Slave DNS Server Configur...   Caching DNS Server Configuration: 👉    • Caching DNS Server Configuration | Linux D...   DNS Forwarder Configuration with Caching DNS: 👉    • DNS Forwarder Configuration with Caching D...   Forward Zone Configuration For DNS Forward Lookup: 👉    • DNS Forward Zone Configuration For DNS For...   Reverse DNS Configuration For DNS Reverse Lookup: 👉    • Reverse DNS Configuration For DNS Reverse ...   DNS Records A, PTR, CNAME, NS, MX, SOA, TXT: 👉    • DNS Records A, PTR, CNAME, NS, MX, SOA, TX...   🔔 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/mailservergur... ★☆★ CONNECT ON SOCIAL MEDIA ★☆★ 👉 𝗟𝗶𝗻𝗸𝗲𝗱𝗜𝗻:   / munnavai   👉 𝗙𝗮𝗰𝗲𝗯𝗼𝗼𝗸:   / mailserverguru   👉 𝗧𝘄𝗶𝘁𝘁𝗲𝗿:   / mailserverguru   𝗔𝘂𝘁𝗵𝗼𝗿: 𝗠.𝗠.𝗥𝗮𝗵𝗺𝗮𝗻 𝗠𝘂𝗻𝗻𝗮 || 𝗺𝘂𝗻𝗻𝗮𝘃𝗮𝗶@𝗴𝗺𝗮𝗶𝗹.𝗰𝗼𝗺 || 𝟴𝟴𝟬𝟭𝟵𝟭𝟮𝟬𝟲𝟰𝟰𝟴𝟯
