    • getDnsLookupFamilyValue

      public int getDnsLookupFamilyValue()
       The DNS lookup family to use during resolution.

 [#comment:TODO(mattklein123): Figure out how to support IPv4/IPv6 "happy eyeballs" mode. The
 way this might work is a new lookup family which returns both IPv4 and IPv6 addresses, and
 then configures a host to have a primary and fall back address. With this, we could very
 likely build a "happy eyeballs" connection pool which would race the primary / fall back
 address and return the one that wins. This same method could potentially also be used for
 QUIC to TCP fall back.]
