LiveStream 5 Administration Guide

Valid Device Identifiers

Each Device Identifier that's added to a Device Group must match the criteria outlined by the relevant networking specification in order to match the data contained in the actual web requests.

LiveStream 5 simplifies this by automatically detecting the type of—and validating—each new identifier that's added. The interface will either automatically format the identifier for you, or let you know if there's a problem.

As discussed in the Device Group introduction, there are three types of network information you can use to identify devices on your LAN:

  • IP address or range — Great for when your client devices have either static IPs or separate DHCP ranges.
  • Subnet — Great for networks where multiple VLANs communicate with the proxy.
  • MAC Address — Great for networks with a limited number of devices where each device's MAC address can be pre-registered in a device group by an administrator.


Every identifier that's added is accompanied by a custom label which describes the type of device it's targeting.

ProTip: Be as specific as possible when labelling your Device Identifiers. For example, if your Device Group is called Guest Devices don't call the identifier within "Guest Devices" as well, refer to it by what it is e.g. Guest WiFi subnet or Guest DHCP range etc.

If the identifier is a specific IP or MAC address then you probably know who the device belongs to and can use a label like Frank's iPad or Gus' laptop etc.

IP Addresses and Ranges

No doubt you are familiar with IPv4 IP addressing dot-decimal format which is used by most operating systems and Local Area Networks. You can use this type of identifier to target devices by their static IP addresses or a range of them.

IP ranges should be entered in the format of start.address-end.address e.g.




If your LAN is separated into logical subnets—using VLANs or the like—then you are probably already familiar with CIDR notation.

In following this format, LiveStream 5 expects subnets to be entered accordingly: network.identifier.address/mask.bits e.g.



MAC Addresses

A MAC address is the most unique type of identifier in that it refers to the physical network hardware of a device. It is possible to spoof another device's MAC address, but in general MAC-based identifiers will be used to authorise access for a specific device whose IP address may change over time.

IMPORTANT: MAC addresses are transmitted over the network via ARP and therefore will not traverse VLANs.

You can typically locate the MAC address of a device on a sticker on the chassis or from within the operating system itself. Follow the links below for instructions on locating the MAC address in specific operating systems:
