Hi,

We've got a number of boxes we'd like to consolidate - this could mean upward of 1,500 IP's on a single box (9.1 amd64).

Last time we did anything like this we hit at issue at around 900 (ntpd 'binds' by default to all available IP's - I think we had a workaround for that).

But is there any hard limit we're likely to encounter putting so many IP's on a single machine? - Are there any limits that would likely need tuning to support that many IP's?


all on one interface?
do you really need so many addresses?
what are you trying to achieve?
you can make a machine accept work for many addresses without actually assigning those addresses to any interface on the machine (see ipfw fwd)


Thanks,

-Karl
