ifconfig is a Linux/Unix command, ipconfig is for Windoze. –  Anthon Nov 18 at 11:01

The ifconfig command is used to get the information of active network-interfaces in a Unix-like operating system such as Linux, whereas ipconfig is used in the Windows OS.

It seems your post add nothing to what is already included Eugene's answer, does it? –  Stéphane Gimenez Sep 17 '12 at 18:53

ipconfig (internet protocol configuration) in Microsoft Windows is a console application that displays all current TCP/IP network configuration values and can modify Dynamic Host Configuration Protocol DHCP and Domain Name System DNS settings.

ifconfig (short for interface configuration) is a system administration utility in Unix-like operating systems to configure, control, and query TCP/IP network interface parameters from a command line interface (CLI) or in system configuration scripts.

dhcpcd is a DHCP client. It is used to obtain an IP address and other information from a dhcp server, renew the IP address lease time, and automatically configure the network interface. The program performs a similar function as dhclient.

dhcpd is a server side implementation of the DHCP protocol (the ending d usually means "daemon" which is the Unix equivalent of Windows services). –  Ouki May 28 '12 at 8:10

ipconfig is also the name for an linux dhcp client/tool to configure network device with klibc. This is mostly used in early user space, e.g. initramfs –  Ulrich Dangel May 28 '12 at 12:42
    
ipconfig is used in initramfs by Ubuntu et al, not by Fedora et al. –  fpmurphy1 May 28 '12 at 13:29
