[Opera-Linux] Flushing the DNS cache?

[Daniel Pittman]

G'day.

I run into occasional problems with Opera on my laptop, when I suspect
inside a client network and resume outside it.

Specifically, when I work inside the network a DNS lookup of
www.example.com returns a private 192.168.0.0 address, while a DNS
lookup outside their network returns the routable Internet address.

As far as I can tell Opera is caching these DNS results, even if the
local DNS resolver, etc, is returning the right stuff, and the only way
I can find to flush that cache is to restart opera.


Is this the expected behaviour, and if so, is there any way to disable
the DNS cache in Opera[1], or to flush it automatically or manually?

Regards,
        Daniel

Footnotes: 
[1]  I run bind9 local to the machine, so my DNS server is *really*
     close, and I don't object to using that instead of an in-process
     cache. ;)
