How do PTR records work?
While the main purpose of the Domain Name System is to point domains to IP addresses, a PTR record works in the opposite way – it associates an IP with a domain name. Because of its purpose, a PTR record is sometimes called Reverse DNS Record. … One PTR record can be configured per IP, linking that IP to a single domain.

Why PTR record is created in DNS?
A PTR record (Pointer Record) connects an IP address to a host name. A PTR record is therefore sometimes called Reverse DNS Record because it converts an IP address into a name. A PTR record can only be created on the nameservers managed by the owner of the IP address, and is only valid for static IP addresses.
Are PTR records necessary?
You need a PTR record because many mail servers will reject email that comes from a mail server without one. After all, the goal is to keep the spam out of your inbox.
What is Reverse DNS used for?
A reverse DNS lookup is a DNS query for the domain name associated with a given IP address. This accomplishes the opposite of the more-commonly-used forward DNS lookup, in which the DNS system is queried to return an IP address.
What is my DNS server number?
The easiest way to find out your dns server IP address is to go through the router’s admin interface status page. All routers have a built-in web-based setup page that allows the user to customize settings and set view properties such as IP address and dns settings.
Why do we need reverse DNS lookup?
The reason we use reverse DNS is the same as why we use the standard (forward) DNS. It is easier to remember and identify a domain name than a string of numbers. rDNS is less crucial than forward DNS, as forward DNS records are required to resolve a website. Domains will still load without a reverse DNS record.
What are the DNS record types?
What are the most common types of DNS record?A record – The record that holds the IP address of a domain.CNAME record – Forwards one domain or subdomain to another domain, does NOT provide an IP address.MX record – Directs mail to an email server.TXT record – Lets an admin store text notes in the record.More items…
Where are PTR records stored?
PTR records are not stored within your domain zonefile, they are stored in a zonefile usually managed by your service provider or network provider. Some service providers provide an interface where you can create the PTR record yourself, others require you to submit a support request to create or change the PTR record.
Why are PTR records important?
A PTR record, or pointer record, enables someone to perform a reverse DNS lookup. This allows them to determine your domain name based on your IP address. Because generic domain names without a PTR are often associated with spammers, incoming mail servers identify email from hosts without PTR records as spam.
