Flush the DNS cache in Mac OS X Leopard

Can anyone tell me the benefits of the following:

==

To flush the DNS cache in Mac OS X Leopard:-

- type lookupd -flushcache in your terminal to flush the DNS resolver cache.

ex: bash-2.05a$ lookupd -flushcache

- Once you run the command your DNS cache (in Mac OS X) will flush.

==

I am on BB with sustained 8 to 9 meg speed. I found this item about flushcache on my hosting service information page.

When and why would you carry out this intruction and what would be the result?

Ciao

Hello:

I have no clue why your ISP hosting service would suggest such an action. Without background, it looks like some sort of troubleshooting step. If you are not having problems with performance, I would not use those arcane terminal commands.

Thanks for feedback. I found out it is a troubleshooting step only if your problem is with their servers and only should the need arise.

"Johnson Creek" sound like a great place.
