use of DNS query ID in connection map key is probably going to lead to issues

[Phillipmartin]

DNS ID is a 16 bit value. In large environments this may not be enough space to prevent collisions. We split the traffic up over an arbitrary number of goroutines, so a simple fix is to spin up more goroutines such that each routine gets fewer values and lowers the chances of collision. A long term solution probably involves adding some other items to the map key.
