      Use Case

      As a Node.js Driver user
      I want the driver to attempt to use all A and AAAA records for each hostname
      So that the driver automatically handles connecting to exclusively IPv4 or exclusively IPv6 bound servers without needing configuration changes.

      User Impact

      • Users will be able to connect to servers bound to IPv4 or 6 or both addresses
      • Driver will prefer IPv6 addresses

      Dependencies

      • Node 18.13+ required

      Unknowns

      • None

      Acceptance Criteria

      Implementation Requirements

      • Allow autoSelectFamily and autoSelectFamilyAttemptTimeout options on MongoClientOptions
      • Default autoSelectFamily to true
      • Pass the options through to socket and TLS socket connection.

      Testing Requirements

      • Add spy to ensure options are passed through to regular and TLS sockets.

      Documentation Requirements

      • Remove note about handling for IPv4/6 from readme

      Follow Up Requirements

      • None.
