Only one entry returned for servers with the same name

[andreynech]

If there are multiple instances of the same server (same name) running either on different hosts or, for example, on the same host listening on different ports, then only one entry is returned by resolver.

I think it is the same problem as described by closed issue 39

Same problem...maybe only one server can accept the query packet，code
one server with one entry, other server can't accept the query packet and response the entry.
I guess.
