parsing multicast-dns responses results in unreachable device

[catdad]

When I use this module, I get an ETIMEDOUT error connecting to a strange IP address 198.105.244.228. The real IP of my chromecast on my network, however, is 192.168.1.105. I did a bit of investigation and found that the host which is parsed from the multicast-dns results is 072d136d-9716-69e2-2758-36bf56482f43.local, and when I do a dns.lookup() on it, sure enough, it resolves to that strange IP address.

Looking a bit further, I saw what appears to be the issue in the multicast-dns responses. On my network, the answers and additionals that I get are these:

answers: [

    "name": "_googlezone._tcp.local",
    "type": "PTR",
    "class": 1,
    "ttl": 120,
    "flush": false,
    "data": "3e0de4d2-1dc6-b2b9-e93d-d3eadf2a301a._googlezone._tcp.local"
  }
]

    }
  },
  {
    "name": "072d136d-9716-69e2-2758-36bf56482f43.local",

  }
]

Looks like there is an A type additional that has the correct IP address. However, this additional is never even looked at. The SRV additional which is used has data.target strange address which resolves to the strange IP.

When I overload the player.host with the correct IP, the module works well and can cast media. However, since the A additional uses different name than the one in the rest of the additionals (and the one used to store cast devices), I am not totally sure how to fix it, since I don't know what other dns responses look like (since I assume this works well on other people's networks).

I added this code, which seems to make it work for me:

  if (a.type === 'A') {
    var aName = name.replace('.local', '');
    Object.keys(casts).forEach(function (castName) {
      if (castName.indexOf(aName) > -1) {
        casts[castName].host = a.data;
      }
    });
  }
