winipcfg on Windows is most commonly used to find out your current IP address.
umm, depends on what you really want.. but you could start with:
Applications -> Utilities -> Terminal -> then type "ifconfig"
which stands for interface configuration.. I think
winipcfg is all good in a Windows 9x world but try that command on a new install of an NT based system. NT based platforms you use ipconfig and for a Unix based platforms are ifconfig.
Thanks for clarifying. I could have sworn I used winipcfg on Windows XP, but apparently not. What about Windows 2000?
What's the OS X equivalent to ipconfig/flushdns?
If You Want The MAC Address You Need To Use The Command ipconfig /all in Windows NT Based Systems and ifconfig -a in Linux Based Systems and i would assume this applies to Mac OS As It Is A Linux Variant At Its Core
dscacheutil -flushcache
