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?

What is the definition of a PTR record?
A PTR record (also known as a Pointer record) is a type of DNS record used to map an IP address to a domain name. Most commonly, PTR (“Pointer”) records are used for reverse DNS lookups, which map an IP address to a domain name for the purpose of verification and audit logging. The PTR record is usually associated with an A record, which maps the domain name to its associated IP address. The Pointer record is usually stored on the name server for the IP address’s reverse domain. To create a Pointer record, it’s necessary to configure the appropriate settings on the name server for the reverse domain. This may involve contacting the hosting provider sometimes, or if the settings are already available, it may include configuring the record directly.
