#connect(family = Socket::AF_UNSPEC, addrinfo_flags = 0) ⇒ Object

Connects to this Reply. If #target and #port are missing, DNSSD.resolve is automatically called.

family can be used to select a particular address family (IPv6 vs IPv4).

addrinfo_flags are passed to DNSSD::Service#getaddrinfo as flags.
