Manually Flushing DNS Cache

G

Guest

Hi,

I have my pc set to flush dns cache automatically but when I do it myself,
Start > Run > cmd > ipconfig/ flushdns, my pc run runs much faster until the
next time I do it a few days later. Someone thinks that it may harm her pc
but, from my experience, I don't think it can. Could any negative side
affects be expected by doing this?

The default time period for keeping an address in the cache is 30 minutes.
So what are you hurting? Nothing.
