V6 Gateway is not reported in the UI. However, in this case, the probe has it and reports it. Probe 2285, the gw start with fe80 and ends wiht 341c.  

At the moment the only way to add V6 resolver is add it statically; you can add just resolvers(add both v4 adn v6). 
Probe Settings
 Change Probe's Network Configuration. 
  Change DNS servers.
