Course Orientation: Intro to Domain Hosting7:09
Explore the essentials of public DNS, domain hosting, and domain registration, from hosting websites to integrating email services like Google Apps.
What You Will Learn?8:30
Learn how public DNS translates names to IPs, register a domain, host a website, connect your domain to email services, and protect it from domain theft and squatting.
Understanding DNS Hierarchy & DNS Tree Structure18:36
DNS resolution translates domain names to IP addresses through a DNS resolver and a root to TLD hierarchy, including forward and reverse lookups, zone files, and TTL propagation.
DNS Terminology & Resolution process (Recursive & Iterative Query)12:29
Dns terminology and the recursive and iterative resolution process, mapping domains from root to tld to host, and using dns resolvers and caches to connect users.
DNS Authorities and Operators9:57
Explore how DNS is operated by IANA, root servers, and registrars, and how 13 root servers manage the root zone and TLDs, with IPv4, IPv6, and quad A records.
Registering a Domain7:23
Register a domain by searching availability, selecting cyber security hub.io, adding to cart, and completing checkout, then manage hosting options and activate the domain after payment.
Purchasing Web Hosting Space and Connecting to the Domain6:28
Purchase Linux shared hosting and connect your cyber security hub.biz domain by adding an A record to the hosting IP, demonstrating DNS setup and domain-hosting linkage.
Connecting Domain to Email Services by Google Workspace9:30
Connect your domain to Google Workspace to route email through Gmail, update MX records in GoDaddy, activate a Google Workspace plan, and understand propagation timelines.
Manually Integrating Email Services using MX Records26:10
Learn how to connect a domain to Google Workspace by configuring DNS, adding and verifying MX records, and managing mail hosting for Cyber Security Hub online.
Demistifying Google MX Record change from 5 to 12:54
this session explains google workspace's april 2023 shift to a single mx record for new customers, using smtp.google.com with a verification record, with no impact on mail delivery.
DNS Records - Address Record (A and AAAA) Record6:03
Explore how the a record and the quad a record map a domain to IPv4 and IPv6 addresses, and how to configure them in a DNS control panel.
DNS Records - CNAME (Canonical Name) Record5:18
Demonstrate how a CNAME record creates an alias by pointing www.your-domain to your-domain, so both resolve to the same IP address via the A record in DNS management.
DNS Records - MX (Mail Exchange) Record4:44
discover how MX records deliver email for your domain by prioritizing mail servers, using Google Workspace MX records, and failing over to lower-priority servers when needed.
DNS Records - SOA Record6:47
Explain the soa record, the start of authority, as the primary dns zone information, including the name server, serial number, and timing parameters like refresh, retry, expiry, and ttl.
DNS Records - NS (Name Server) Record6:44
NS records delegate a DNS zone to authoritative name servers and identify the primary name server for a domain, with propagation and authoritative versus cached answers.
