It would be nice if the device tracker search had the option for Regex usage within it. This came up recently to search for mac addresses on the network that may come from randomized MAC address generated from android / ios devices. Searching manually isn't feasible, however with Regex it would be simple to change the filter to MAC address only for the search and maybe check a regex box or something to indicate you are using Regex for your search and enter your criteria. It can even be used to search for IP address of specific subnets across multiple locations using the similar technique.
