In my internal work network, whenever I launch
dig against a particular hostname, I get result similar to this:
;; ANSWER SECTION: some.internal.host.com. 10 IN A 10.210.54.121
If I keep spamming the same
dig some.internal.host.com command, the response always has a single A record, but the IP address is changing between calls.
I assume it is some form of load-balancing, but the full list of IP addresses in the pool is hidden from inquisitive persons.
What could be the technique that is used here to achieve the described result?
