DNS propagation is the time Domain Name System servers worldwide take to update and propagate information about a domain name. It occurs when changes are made to the DNS information associated with a domain name, such as an IP address change or new DNS records being added. During Domain Name System propagation, different DNS servers can have different versions of the DNS information cached. This is why a website may appear inaccessible or show the wrong content sometimes. Domain Name System propagation typically takes between 24 to 48 hours to complete, depending on the number of DNS servers involved. Read more about the purpose of DNS propagation and what affects it?

DNS records: What do you need to know?
Computers use DNS records to locate each other and exchange data on the internet. Domain Name System records are stored in a Domain Name Server and can be viewed with a tool such as DIG. DIG is an acronym for Domain Information Groper, an easy-to-use command-line utility software that queries Domain Name System records for a given hostname. It can display various types of Domain Name System records, including but not limited to A, AAAA, CNAME, MX, NS, PTR, SOA, SRV, and TXT. By providing a hostname to DIG, a Domain Name System record lookup can be initiated, allowing the user to easily view, check and analyze the Domain Name System records of any domain. FInd detailed guide on how to check DNS records with DIG command.
rDNS: Detailed explanation
Reverse DNS (rDNS) is essential to the Domain Name System (DNS). While a forward DNS query uses an IP address to find the domain name of a specific website, rDNS does the opposite—it translates a domain name into its associated IP address. This helps validate an email address and ensures that the domain name’s owner is hosting an email server or a website. It is also essential for Internet Service Providers (ISP) to maintain a consistent history of WHOIS records, which provide details such as the contact name, address, and phone number associated with a domain name. rDNS is a key step toward ensuring the security of websites, email servers, and end users.
