> Reverse DNS (PTR) records are not stored in a forward private DNS zone. Reverse DNS records are stored in a reverse DNS (in-addr.arpa) zone. The default reverse DNS zone associated with a vnet isn't viewable or editable.

You can disable the reverse DNS function in a virtual network by creating your own reverse lookup zone using [Azure DNS private zones](../dns/private-dns-overview.md), and then linking this zone to your virtual network. For example, if the IP address space of your virtual network is 10.20.0.0/16, then you can create an empty private DNS zone **20.10.in-addr.arpa** and link it to the virtual network. This zone will override the default reverse lookup zones for the virtual network and since this zone is empty you'll get **NXDOMAIN** for your reverse DNS queries, unless you manually create these entries. Auto-registration of PTR records isn't supported, so if you wish to create entries, these must be entered manually. You must also disable auto-registration in the vnet if it's enabled for other zones due to [restrictions](../dns/private-dns-autoregistration.md#restrictions) that permit only one private zone to be linked if autoregistration is enabled. See the [private DNS quickstart guide](../dns/private-dns-getstarted-portal.md) for details on how to create a private DNS zone and link it to a virtual network.

> Since Azure DNS private zones are global, you can create a reverse DNS lookup to span across multiple virtual networks. To do this, create a reverse lookup zone (in-addr.arpa) [Azure DNS private zones](../dns/private-dns-overview.md) and link it to the virtual networks. You'll have to manually manage the reverse DNS records for the VMs.
