Hi,
I can't find a way to do the following although I invested plenty of time
in research - maybe you guys have an idea:
With bind, I'd need to serve a single A record with 30+ IP addresses and
these addresses have to be returned in random order round robin,
which is done with:
rrset-order { order random; };
and records like:
foo IN A 10.0.0.1
foo IN A 10.0.0.2
foo IN A 10.......N
Now I'd like bind to just return a random subset of e.g. 5 IP addresses
if someone requests this A record.
Reason for this are in my case some (thousands) older clients (that I can't
control)
that seem not being able to handle that many IPs - the OS resolver just returns
an error.
For my use case I absolutely need to make sure that each IP of that large
A record set is given out equally (statistically) and that at any time when
bind answers that one A record it only returns a random subset of all these IPs.
Has someone an idea on how to achieve the latter?
Thanks a lot in advance!
