In case anyone else needs this information, I’ve just figured out that ipconfig /flushdns that we use in the Windows world translates to lookupd -flushcache in Unix/Linux/Mac OS X/BSD.
Flushing Stale DNS in Unix

It does?
I certainly don’t have any “lookupd” on any of my Linux boxes.
As far as I know, Linux (and most other Unix variants) doesn’t cache DNS lookups at all; however, individual applications might do so. Firefox is notorious for this.

Yeah and actually it’s on CentOS as well as OS X. I’ve used it quite a bit recently. Generally the times I need it come when I start hardcoding /etc/hosts to migrate blogs, etc. Happens in Firefox and Safari, so… yeah. :)

So how does that differ from rndc flush?
Aaron Brazell 02.07.07 at 11:13 am
Not saying it is different. It’s just how I do it.

rndc flush deals with the nameserver itself, not the workstations which use the nameserver.
In any case, I still haven’t even been able to FIND a lookupd on CentOS. What package is it in?
It certainly sounds like you’re doing absolutely nothing — or something quite different from Windows.

Michael, you’re right. My bad. I thought I had used it on our servers but I hadn’t and it’s not on Linux (will update entry). It’s a BSD sysutil (and thus on OS X).
