What should my PTR record be?
PTR records are used for the Reverse DNS (Domain Name System) lookup. Using the IP address you can get the associated domain/hostname. An A record should exist for every PTR record. The usage of a reverse DNS setup for a mail server is a good solution.
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.
How do I find my DNS name?

Where are DNS records stored?

How does a PTR record 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.
What is the use of PTR in DNS?
A pointer (PTR) record is a type of Domain Name System (DNS) record that resolves an IP address to a domain or host name, unlike an A record which points a domain name to an IP address. PTR records are used for the reverse DNS lookup. Using the IP address, you can get the associated domain or host name.
Where is PTR record 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.
Are PTR records necessary?
You need a PTR record because many mail servers will reject email that comes from a mail server without one.
What is A and AAAA record?
An AAAA record maps a domain name to the IP address (Version 6) of the computer hosting the domain. An AAAA record is used to find the IP address of a computer connected to the internet from a name. … As with the A records, you can use multiple AAAA records for the same domain in order to provide redundancy.
What is a PTR record in DNS?
A DNS pointer record (PTR for short) provides the domain name associated with an IP address. A DNS PTR record is exactly the opposite of the ‘A’ record, which provides the IP address associated with a domain name. DNS PTR records are used in reverse DNS lookups.
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.
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…
How long does it take for a PTR record to propagate?
24 hoursThe general rule is propagation takes 24 hours to complete worldwide. However, in some cases, this can take up to 48 hours, depending on DNS record TTLs.
What is an A record domain?
A Records. A Records are the most basic type of DNS record and are used to point a domain or subdomain to an IP address. Assigning a value to an A record is as simple as providing your DNS management panel with an IP address to where the domain or subdomain should point and a TTL.
