Private DNS

This article describes how to configure a private DNS.  

Private DNS will enable you to reach an internal resource by its hostname (as published by your local DNS server). This can ease your workflow, as you will no longer need to specify the resource's IP address and will be able to resolve resources that are not directly exposed to the Perimeter 81 Network.

You can assign Private DNS on two different levels: on the Network level (for the entire Network) or on the Region level (for a specific region in your Perimeter 81 Network). 

The Private DNS will allow you to utilize your organization’s DNS servers, as well as local domain names while the Regional DNS will allow your users to resolve resources via a local DNS server rather than waiting for a response from a remote one.

Connecting a Private DNS to a Network

A Private DNS server can be connected to the Perimeter 81 Network by following those steps: 

Before you proceed
If your private DNS server(s) do not have a public IP address, you'll need to set up a Site-to-Site connection to the internal network containing the server(s).

  1. Click on the (...) icon on the Network section.

2. Click on Private DNS.

3. Turn-on the Enable Private DNS toggle.

If your Private DNS Server(s) supports DoT you'll need to turn the DNS over TLS on (otherwise your requests will be sent over HTTPS).

4. Enter the IP address of each one of your DNS servers. You can enter up to four different IP addresses.

All private DNS servers should be fully synced as the system will only be resolving addresses through one of the servers.
Do not configure public DNS servers (such as 8.8.8.8, 1.1.1.1, etc.), as all requests will be forwarded to them if the private DNS server won't resolve the address.

5. Wait for the Network status to change from Deploying... to Active.

Connecting a Private DNS server to a Region

  1. Click on the (...) icon on the desired Region.

2. Turn-on the Enable Private DNS toggle.

If your Private DNS Server(s) supports DoT you'll need to turn the DNS over TLS on (otherwise your requests will be sent over HTTPS).

3. Enter the IP address of each one of your DNS servers. You can enter up to four different IP addresses.

All private DNS servers should be fully synced as the system will only be resolving addresses through one of the servers.
Do not configure public DNS servers (such as 8.8.8.8, 1.1.1.1, etc.), as all requests will be forwarded to them if the private DNS server won't resolve the address.

4. Enter any suffix that you'd like to add to the DNS query (for example, if you enter perimeter81.com as a search domain, and then type in the address bar support, you'll be directed to support.perimeter81.com).

5. Select apply, then wait for the Network status to change from Deploying... to Active.
