This software <https://github.com/SivanLiu/HwFrameWorkSource> seems to
use the string for in-band signaling:

|   if (dhcpResults != null) {
|       WifiStateMachine.this.stopIpClient();
|       dhcpResults.domains = "getCachedDhcpResultsForCurrentConfig";


I can't read the README file unfortunately, but perhaps it's
sufficiently widely deployed to explain the observations.
