System setup

To ensure that all DNS Edge features work properly, ensure that your network configuration meets the following requirements.


You must operate DNS Edge in an IPv4 environment. DNS Edge isn't supported in IPv6 environments.

Cloud Access

Your firewall should allow for:

  • Inbound and outbound access as described in DNS Edge ports.
  • HTTPS proxy bypass (if relevant).

For service points to successfully register and communicate with the DNS Edge cloud, they must be able to connect to and resolve the endpoints listed in the cloud access requirements.

Finally, if the service point isn't configured with a custom static NTP server, it needs to be able to communicate with the default group of NTP sources:
  • * (include the asterisk)

Virtual Machine

Minimum requirements for your virtual machine:

  • 4GB of memory, 2 vCPU @ 2GHz, 25GB of disk space
  • BlueCat recommends upgrading the memory capacity to 8GB when using Threat Protection policies.
  • DNS Edge does not support the oversubscription of resources.

It's best to deploy the virtual machine in a network with access to a DHCP server.

Client devices

You should configure client devices on your network to point at the DNS Edge site IP address as the resolver. Deploy the site in the same network as the DNS clients (or in such a way that no translation of address is performed) so the site can see the client IP addresses part of UDP datagrams.

DNS Edge administration device

The client device from which you log in to the DNS Edge web application must have unrestricted HTTPS access to the following end points (where <customerURL> is the URL of your DNS Edge instance):
  • <customerURL>
  • api-<customerURL>
  • You must add security exceptions for the DNS Edge web application in any privacy browser extensions.
  • You must enable third party cookies on your browser to access the DNS Edge web application.
Note: To upload a list of domains, the client device from which you log in to the DNS Edge web application must allow multipart/form-data uploads.

Forwarding DNS

The default DNS forwarder is set to After you log in to DNS Edge, you can customize the default DNS forwarders for your organization to save time when you create your sites. See Namespaces and forwarders.
