IPConfig originally came about in at least as far back as NT 4.0, maybe even further. In that older version it was only a
handy display tool, showing the network hosts current IP
configurations. The equivalent version in Windows 9X is
'winipcfg' which no longer exists in these newer operating
IPconfig commands in NT 4.0 and newer
Displays current IP settings in detail
Instructs the network host to release the DHCP assigned.
Instructs the network host to request a new IP address from the DHCP server.
NOTE: using the renew command implies a release.
IPconfig commands in Win2k and newer
Instructs the network host to dump all cached DNS entries.
Instructs the network host to display all cached DNS entries.
Instructs the network host to register its hostname and IP dynamically to the local DNS servers.
For me, the "flushdns" command is the most commonly used command besides ping.
With the Win9X and NT4.0 platforms, whenever I made an IP change to a DNS entry I had to reboot the machine
for it to get the new address because the machine would cache the old one until it was rebooted.
