What is my PTR record?
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.
How do I find the DNS name of an IP address?
Type “nslookup %ipaddress%” in the black box that appears on the screen, substituting %ipaddress% with the IP address for which you want to find the hostname. Find the line labeled “Name” underneath the line with the IP address you entered and record the value next to “Name” as the hostname of the computer.
How do I view PTR record in Linux?
Method 1 – Checking PTR with nslookup or dig

Why do we need reverse DNS lookup?
Reverse DNS Lookup. DNS is typically used to resolve a domain name to an IP address. This act is known as a forward resolution and enacted every time you visit a site on the internet. Reverse DNS (rDNS), as its name implies, is a method of resolving an IP address to a domain name.
What is reverse IP lookup?
What is a Reverse IP Lookup? The technique known as Reverse IP Lookup is a way to identify hostnames that have DNS (A) records associated with an IP address. A web server can be configured to server multiple virtual hosts from a single IP address. This is a common technique in shared hosting environments.
Where are PTR records stored?
The A record for www is stored within the zone file for wordtothewise.com. PTR records are not stored within your domain zonefile, they are stored in a zonefile usually managed by your service provider or network provider.
Do I need a PTR record?
There should be exactly one PTR record per IP address/name pair. Each IP address should have a PTR record. The convention is, that name’s IP address must have a PTR record that resolves back to the name used in the MX record. There should be an A record for every PTR record (but not necessarily vice versa).
What is the purpose of PTR records?
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.
How do I identify the owner of an IP address?
If you have the IP address you are trying to find the owner for, you can go to a database website such as http://ws.arin.net/whois/ to find the owner. Merely type the IP address (making sure to get all the numbers and periods correct) into the field provided, and you will get the owner of the address.
How do I find my FQDN?
To find the FQDN
- On the Windows Taskbar, click Start > Programs > Administrative Tools > Active Directory Domains and Trusts.
- In the left pane of the Active Directory Domains and Trusts dialog box, look under Active Directory Domains and Trusts. The FQDN for the computer or computers is listed.
How do I find out what my DNS is?
Type or paste the “ipconfig /all” command (without the quotation marks) into the Command Prompt and press “Enter” to run it and get detailed information about the network. Locate the IP address of the computer in the “IPv4 Address” field. Locate the primary DNS IP address in the “DNS Servers” field.
What is DNS AAAA record?
The record A specifies IP address (IPv4) for given host. A records are used for conversion of domain names to corresponding IP addresses. IP Version 6 Address records (AAAA) The record AAAA (also quad-A record) specifies IPv6 address for given host.
What is nslookup command?
nslookup is a network administration command-line tool available in many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping, or other DNS records.
How do I setup a PTR record?
Go to DNS menu and select Managed DNS.
- Either search for or select the domain you just created.
- Click the plus sign in the PTR records table to add a new record.
- Enter the following values for the PTR record: A. The name value of the PTR record will be the last octet of your mail server’s IP address.
What is a reverse check?
Reverse a check if there was an error and the employee has already cashed the check or has deposited it via ACH. A reversal will create an Advance Bank transaction which will deduct or add funds to the employee’s future paycheck to remove the outstanding balance. Taxes are always tied to the date on the check.

- Enter your domain name in the search field and click Lookup.
- In the results page, look for the Registrar section for the name of your domain host and website.
Do you need reverse lookup zone DNS?
You need reverse DNS to match IP Addresses to Host Names. You don’t need to set up another DNS server for reverse lookup, your existing DNS server should be configured to do it – i.e. if it doesn’t exist, create a Reverse Lookup Zone.
