On Windows 2000 and XP systems the ipconfig command can
be used to establish if a NIC has successfully bound to the required IP
address.
Sometimes a
NIC will not release an old IP address. Using the ipconfig
/release command option forces the NIC to release the currently held
address. Following with the ipconfig /renew command causes
the NIC to attempt to bind to an address supplied by a DHCP server, or to a
manually configured IP address.
For UNIX and Mac OS X end-systems the
ifconfig –a command can be used to establish if a NIC has
bound to the correct IP address.
