Troubleshooting Dante IP Address Configuration

All devices in a Dante network, including Dante Virtual Soundcard, must be using IP addresses from the same network. When using Dante Virtual Soundcard or Dante Controller, your PC or Mac must be connected to the Primary and/or Secondary Dante network, and must have a correct IP address.

Note:  If a device name is shown in red, it means Dante Controller has automatically detected an error condition, such as an IP address configuration issue, or the device has entered failsafe. Double-click the red device name to see more information.

Correct IP configuration

Dante hardware devices are set to obtain their IP address automatically from the network. They will either:

  • Automatically assign themselves an address in the range 169.254.*.* (172.31.*.* for the secondary network if present), or
  • Obtain an IP address from a DHCP server if it is present on the network

Your PC or Mac TCP/IP network configuration set should be set to 'Obtain an IP address automatically'. This way it will automatically acquire a Link Local automatic IP address in the same network as other Dante devices. If a DHCP server is present, the computer and Dante devices will all acquire their IP addresses via DHCP.

Possible IP network configuration mistakes

Possible network configuration errors are listed below. Dante Controller will try to automatically detect these. If detected the offending device will be displayed in red.

Incorrect PC/Mac IP configuration

  • Accidentally having multiple network interfaces with addresses in the same subnet
  • If your secondary network is using Link Local (no DHCP server), all devices on that network will be in the 172.31.*.* range. The secondary network interface for the computer must be manually configured (using static IP addressing) to the same range.

Incorrect general IP configuration

  • Accidentally having multiple DHCP servers on the same network

Unusual – for example, someone may have a PC connected to the network with a DHCP server running that they’re not aware of.

  • Incorrectly configured static IP addresses

You shouldn’t typically need to configure static IP addresses at all. If for some reason you do, it must be in the same subnet as the rest of the network.

Incorrect redundant network configuration

Setting up a redundant network is described in 'Routing Audio'. There are a few ways to incorrectly configure a redundant network. More than one of these can be present at the same time.

  • Connecting the secondary interface of a Dante device to the primary network

Most commonly by either misunderstanding how redundancy works, and using only one switch with all cables connected to it; or correctly using two switches or networks, but accidentally connecting one secondary cable to a primary network switch

  • Joining the primary and secondary Dante networks

By connecting primary and secondary switches, or perhaps just using one switch.

  • Multiple interfaces on the same device using the same IP address subnet

Possibly by having the same DHCP server on both primary and secondary networks, or both DHCP servers configured to serve the same IP addresses. Also, mixing DHCP and Link Local on the same network can cause issues. It is often necessary to have all devices and the computer on either DHCP or Link Local.

What are the symptoms of using the wrong network interface on my computer?

If you have more than one wired network interface, and Dante Controller is not using the interface the rest of the Dante devices are connected to:

  • Dante Controller cannot see any Dante devices
  • Dante Virtual Soundcard is not sending or receiving any audio when it is expected to

How do I check which network interfaces Dante Controller is using?

  • The selected network interfaces can be viewed or changed via the 'interface selection' button in the Network View toolbar of Dante Controller.

  • If the Dante network is standalone and does not have a DHCP server installed, the addresses should be in the range 169.254.*.*
  • If the Dante network is using a DHCP server, the IP addresses should conform to the addressing scheme it is using (as shown in the image above)

How do I check IP addresses for all devices on my network?

  • Use the Device Info tab to view the IP addresses of all the devices on your network.

  • The Primary Address of all devices should follow the same IP address scheme (e.g. 169.254.*.* or 10.12.0.*). Same for secondary addresses…
  • Note that some older Dante devices or devices running older firmware may not show this information.
