Windows Dns Adding A Ptr Record
Because of its purpose, a PTR record is sometimes called Reverse DNS Record. The purpose of a PTR record is mostly administrative - it shows an IP is in fact used with a particular domain. SiteGround provides PTR records only on Cloud and Dedicated servers. Nov 13, 2013 Click on the Create associated pointer (PTR) record and select Add Host. This will display the successful creation of the record. Select OK and bring back the Add Host window in case multiple. In order to create a PTR record, at first need to be created a Reverse DNS zone (read more about the reverse dns zones here). The reverse DNS zone depends on the size of your IP network. In our example we will use an IPv4 /24 network. In the /24 network, you have 255 unique IP addresses. I have however moved all the A records over to the Windows setup and made sure they are cleaned up. Now I have empty reverse zones. What I am wondering is if there is a relatively easy way to tell the DNS server (Windows 2008 R2, Active Directory integrated), either via GUI or cmd line, to go ahead and create PTR records for all of the A records.
- I created a new PTR record for this IP/hostname and it's showing up with the correct name of '10.1.1.10' on all my servers, except for the one I actually first created it on - on that server, it's showing up as a PTR record with the name '(same as parent folder)'.

- What is 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.
Syntax
Description
The Add-DnsServerResourceRecordPtr cmdlet adds a specified pointer (PTR) record to a specified Domain Name System (DNS) zone.
PTR resource records support reverse lookup based on the in-addr.arpa domain.PTR records locate a computer by its IP address and resolve the address to the DNS domain name for that computer.
Examples
Example 1: Add a PTR record
This command adds a type PTR DNS record in the zone named contoso.com.The record maps IP address 192.168.0.17 to the name host17.contoso.com.The command includes the AllowUpdateAny and AgeRecord parameters, and provides a TTL value.Because the command includes the AgeRecord parameter, a DNS server can scavenge this record.
Parameters
Indicates that the DNS server uses a time stamp for the resource record that this cmdlet adds.A DNS server can scavenge resource records that have become stale based on a time stamp.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Indicates that any authenticated user can update a resource record that has the same owner name.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
The cmdlet immediately returns an object that represents the job and then displays the command prompt.You can continue to work in the session while the job completes.To manage the job, use the *-Job
cmdlets.To get the job results, use the Receive-Job cmdlet.
For more information about Windows PowerShell background jobs, see about_Jobs.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Runs the cmdlet in a remote session or on a remote computer.Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet.The default is the current session on the local computer.
Type: | CimSession[] |
Aliases: | Session |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies a DNS server.If you do not specify this parameter, the command runs on the local system.You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.
Type: | String |
Aliases: | Cn |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Prompts you for confirmation before running the cmdlet.

Type: | SwitchParameter |
Aliases: | cf |
Position: | Named |
Default value: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies part of the IP address for the host.You can use either an IPv4 or IPv6 address.For example, if you use an IPv4 class C reverse lookup zone, then Name specifies the last octet of the IP address.If you use a class B reverse lookup zone, then Name specifies the last two octets.
Type: | String |
Aliases: | RecordName |
Position: | 2 |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Returns an object representing the item with which you are working.By default, this cmdlet does not generate any output.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies an FQDN for a resource record in the DNS namespace.This value is the response to a reverse lookup using this PTR.
Type: | String |
Position: | 3 |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Specifies the maximum number of concurrent operations that can be established to run the cmdlet.If this parameter is omitted or a value of 0
is entered, then Windows PowerShell速 calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.The throttle limit applies only to the current cmdlet, not to the session or to the computer.
Type: | Int32 |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies the Time to Live (TTL) value, in seconds, for a resource record.Other DNS servers use this length of time to determine how long to cache a record.
The Start of Authority (SOA) record defines the default TTL.
Type: | TimeSpan |
Position: | Named |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Specifies the virtualization instance in which the zone will be added.A virtualization instance is logical partition in a DNS Server, which is capable of independently hosting zones and zone scopes.Same name zones and zone scopes can be hosted in different virtualization instances.This parameter is optional and if not provided it will add the zone into the default virtualization instance which is functionally equivalent to a standard DNS server.
Type: | String |
Position: | Named |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Shows what would happen if the cmdlet runs.The cmdlet is not run.
