dns flushing question.

[Jiggy]

I understand that the client sends a DNS query to your ISP DNS server and if that doesnt know it querys the ROOT DNS server, my question: If I use this C:\>ipconfig /flushdns command, which DNS server does it flush ?

Thanks Jiggy.

If you are talking about Windows (at least the latest versions), then it flushes the local cache...

I'm going from memory here, but XP looks up addresses something like this...

HOSTS file -> local DNS cache -> local network DNS server (if there is one) -> first listed/ISP server -> root servers

Hello mjc,

So using ipconfig /flushdns flushes your ISP DNS server, I`ve been reading this site http://www.firewall.cx/dns-resolution.php I use for study. I ask because their seems to be alot of people on the net using ipconfig /flushdns to resolve connection problems but it never says what it flushes, can it flush Windows DNS cache..?

Searching more i`ve found as mjc said it flushes the DNS Windows XP cache or hosts file of negative entries that could stop you accessing a site.
