_tick seems to do the cache clean up based on the ttl on first set.

After deletion, the dns query doesn't get refreshed until the next query invocation. This means that http clients will still occasionally pay the cost of a dns lookup on their hot path. For comparison, coredns does this.

Would it make sense for this library to support a refresh mechanism prior to query expiration?
