Does this give me a new IP address to my computer?  What exactly does ipconfig /flushdns do?  I'm trying to assign a new IP address

Guest Says:
No it wont.  Your computer keeps ip address matching internet addresses for faster access via cache.  Lookups occur against DNS if it doesn't know them already. DNS is the "Domain Name System" that maps IP and addresses.  This will flush the cache so that it has to look them up again, it won't hurt anything using flushdns but you wont get a new IP address.  Years ago it used to work with dialup as new IP addresses were always assigned each time, then with cable or dsl it used to help shutting off the router and turning back on.  Today that doesn't work anymore, your IP is set by the company and changing on your computer will not give you a new IP.

Why do you want to use flushdns anyways?
