How does DNS caching handle fixed order records
If my BigIP LTM DNS Cache receieves a response from the DNS pool with three A records, and caches it, would all subsequent queries recieve the same response ie in the same order
DNS response recieved and cached:
www.example.com 10.10.10.10 10.10.10.20 10.10.10.30
Will later consecutive responses answered from the cache be:
www.example.com 10.10.10.10 10.10.10.20 10.10.10.30
www.example.com 10.10.10.10 10.10.10.20 10.10.10.30
www.example.com 10.10.10.10 10.10.10.20 10.10.10.30
Or will the cache do some kind of random/round-robin technique, eg
www.example.com 10.10.10.10 10.10.10.20 10.10.10.30
www.example.com 10.10.10.20 10.10.10.30 10.10.10.10
www.example.com 10.10.10.30 10.10.10.20 10.10.10.10
Thanks for your help
