A pointer (PTR) record resolves an IP address (made up of numbers and decimals) into a domain name (such asokta.com). The act of translating an IP address into a domain name is known as areverse lookupin the Domain Name System (DNS). Let us explain how this process works. What do...

Reverse the remaining numbers (111.222.3->3.222.111). Add “in-addr.arpa” to your reversed IP address (3.222.111.in-addr.arpa). Your completed reverse zone domain is3.222.111.in-addr.arpa. Step 2) Create PTR Record Add a new PTR record. ...
The Domain Name System (DNS) is the component of the internet standard protocol responsible for converting human-friendly domain names into the internet protocol (IP) addresses computers use to identify each other on the network. Often called the “phonebook for the internet,” a more modern anal...
This zone is administered by whoever owns the block of IP addresses. In the example case, the zone for the PTR record would be 12.62.25.23.in-addr.arpa. The owner of the IP address is usually the Internet Service Provider (ISP) and if you want to add a PTR record to your IP address...
A Domain Name System (DNS) record is a set of instructions used to connect domain names with internet protocol (IP) addresses within DNS servers. DNS makes it possible for users to browse the internet with customizable domain names and URLs rather than complex numerical IP addresses. ...
So, an SPF record checker verifies whether only one record exists or multiple. Maximum Lookups: The maximum number of SPF lookups that must be done is limited to 10. Therefore, the SPF record checker finds out the total number of lookups and whether it exceeds 10 or not. PTR Mechanism: ...
A is the host record, and is the most common type of DNS record. It maps the domain or host name to the IP address. CNAME is a Canonical Name record that's used to create an alias from one domain name to another domain name. If you had different domain names that all accessed the...
