Right now inflight DNS lookups are grouped together.

Since DNS resolution picks the first available IP, this has the side effect of resolving the same IP when there are bursts in traffic.

This was surprising to me since I expected load to be distributed amongst the resolved hosts, especially during these bursts (assuming equal RFC 6724 weighting).

Load distribution via DNS seems like a common use case/expectation - it would be nice to be able to enable randomized DNS resolution. Being able to disable DNS query grouping or customize the way the group key is generated would also work.
