Resolve domain name

[fazibear]

When I'm start a server with following records:

[
  # create domain for an ip
  %Mdns.Server.Service{domain: "somedomain.local", data: :ip, ttl: 450, type: :a},

  # make service discoverable
  %Mdns.Server.Service{domain: "_services._dns-sd._udp.local",data: "_ssh._tcp.local",ttl: 4500, type: :ptr},

  # register ssh service
  %Mdns.Server.Service{domain: "_ssh._tcp.local",data: "SOME NAME._ssh._tcp.local",ttl: 4500, type: :ptr},

  # point service to our domain and port (22)
  %Mdns.Server.Service{domain: "SOME NAME._ssh._tcp.local",data: {0,0,22, 'somedomain.local'},ttl: 4500,type: :srv},

  # empty txt service (some tools expext that)
  %Mdns.Server.Service{domain: "SOME NAME._ssh._tcp.local",data: [],ttl: 4500,type: :txt})
] |> Enum.each(&Mdns.Server.add_service/1)

Tools like Avahi Discovery, Avahi SSH Server Browse, mdns-scan works fine.

But when I'm trying to find device with Mdns.Client the domain is nil.

After a little research this condition https://github.com/rosetta-home/mdns/blob/master/lib/mdns/server.ex#L106 prevent to send :a record witch Mdns.Client is looking for. On the other side other tools resolve domain correctly.

Should Mdns.Server always send :a record od Mds.Client should resolve domain in a different way?

I'm not sure, and haven't been using the library much, but I would love to resolve these issues.

Anyway you could provide a PR? I might be beneficial to fix it on both sides.
