      Description of problem:

      https://github.com/j-keck/arping/blob/c50f4319d307d95d1e2b344c4504158705e919de/arping.go#L227 doesn't support IPV6
      
      We use it here:
      
      func GetMACAddressFromARP(neighIP net.IP) (net.HardwareAddr, error) { 
         hwAddr, _, err := arping.Ping(neighIP)   
         if err != nil { 
             return nil, err   
         }    
         return hwAddr, nil
      }
      
      and so we get errors like:
         2022-08-09T20:35:57.615015621Z E0809 20:35:57.614974   33417 node.go:664] Failed to lookup hardware address for gatewayIP fd13:f100:e876:a09::4: not a valid v4 Address: fd13:f100:e876:a09::4
