+
+Computers use DNS to determine the IP address associated with a domain name. *Reverse* DNS lookup does the opposite by resolving an IP address to a designated domain name. You should always set the reverse DNS, even if your Linode hosts more than one domain.
+
+Reverse DNS uses a *pointer record* (PTR) to match an IP address with a domain or subdomain. PTR records are generally set with a hosting provider, so reverse DNS is set in the Linode Manager.
+
+Before setting the reverse DNS for your Linode, configure your domain zone and DNS records through Linode's [DNS Manager](/docs/platform/manager/dns-manager/). See our [Introduction to DNS Records](/docs/networking/dns/dns-records-an-introduction/) and [Common DNS Configurations](/docs/networking/dns/common-dns-configurations/) guides for more information about PTR and DNS.
+
+## Setting Reverse DNS
+
+1.  Select the Linode you wish to set up reverse DNS for from your Linodes tab.
+2.  Click the **Remote Access** tab.
+3.  Select the **Reverse DNS** link:
+
+    [![The Reverse DNS link](1709-remoteaccess_reversedns.png)](1709-remoteaccess_reversedns.png)
+
+4.  Enter your Linode's fully qualified domain name in the **Hostname** field:
+
+    [![Adding the domain name for reverse DNS](1706-ptr_lookup_marked.png)](1706-ptr_lookup_marked.png)
+
+5.  Click **Look up**. A message will appear indicating that a match has been found for both your IPv4 and IPv6 addresses:
+
+    [![Reverse DNS Match found](1707-ptr_lookup_match_found.png)](1707-ptr_lookup_match_found.png)
+
+6.  Click **Yes** beneath the desired address. Note that you can select only one address at a time. If you want to set up reverse DNS for both the IPv4 and IPv6 addresses, you can perform another lookup and select the other address.

+Reverse DNS uses a *pointer record* (*PTR*) to match an IP address with a domain or subdomain. PTR records are generally set with a hosting provider, so reverse DNS is set in the Linode Cloud Manager.
+
+## Before You Begin
+
+Before setting the reverse DNS for your Linode, configure your domain zone and DNS records through Linode's [DNS Manager](/docs/platform/manager/dns-manager-new-manager/). See our [Introduction to DNS Records](/docs/networking/dns/dns-records-an-introduction/) and [Common DNS Configurations](/docs/networking/dns/common-dns-configurations/) guides for more information about PTR and DNS.
+
+Specifically, you will need to create an *A record* for the domain name (or subdomain) that you want to assign your reverse DNS to. The value of this A record should be the IP address that you're setting up reverse DNS on.
 
 ## Setting Reverse DNS
 
-1.  Select the Linode you wish to set up reverse DNS for from your Linodes tab.
-2.  Click the **Remote Access** tab.
-3.  Select the **Reverse DNS** link:
+1. Click on the **Linodes** link in the sidebar to access a list of all your Linodes.
+
+1. Select the Linode whose reverse DNS you would like to set up and click on its **Networking** tab.
+
+1. Find the IP address whose reverse DNS you would like to set up and click on its **more options ellipsis**. Then, select **Edit RDNS** from the dropdown menu.
+
+    ![Selecting reverse DNS](rdns-edit-select.png "Selecting reverse DNS")
+
+1. In the **Edit Reverse DNS** field, add your Linode's fully qualified domain name and click on the **Save** button.

+If you did not previously set up an A record for your domain that matches your Linode's IP address, you will see an error like the following:
 
-4.  Enter your Linode's fully qualified domain name in the **Hostname** field:
+{{< output >}}
+We were unable to perform a lookup for 'example.com' at this time.
+{{< /output >}}
 
-    [![Adding the domain name for reverse DNS](1706-ptr_lookup_marked.png)](1706-ptr_lookup_marked.png)
+You may also see this error if you very recently created your A record, as it can take some time for your DNS changes to propagate.
+{{< /note >}}
 
-5.  Click **Look up**. A message will appear indicating that a match has been found for both your IPv4 and IPv6 addresses:
+1. You should now see the domain name you entered listed under the **Reverse DNS** column.
