Common uses for ifconfig include setting the IP address and subnet mask of a network interface and disabling or enabling an interface. [1] At boot time, many Unix-like operating systems initialize their network interfaces with shell scripts that call ifconfig. As an interactive tool, system administrators routinely use the utility to display ...
Clients may solicit an IP address from a DHCP server when they need one. The DHCP server then offers the "lease" of an IP address to the client, which the client is free to request or ignore. If the client requests it and the server acknowledges it, then the client is permitted to use that IP address for the "lease time" specified by the server.

Linux IP Firewalling Chains, normally called ipchains, is free software to control the packet filter or firewall capabilities in the 2.2 series of Linux kernels. It superseded ipfirewall (managed by ipfwadm command), but was replaced by iptables in the 2.4 series.
On Linux and all Unix-like operating systems, the utilities ifconfig and the newer ip (from the iproute2-bundle) are used to configure IEEE 802.3 and IEEE 802.11 hardware. These utilities configure the kernel directly and the configuration is applied immediately. After boot-up, the user is required to configure them again.
An IP hopper is an unregistered or anonymous editor whose IP address changes. Mostly this would be completely outside the user's control. Some ISPs automatically assign their users a different IP address with every edit. Others may change IP address every few minutes, every few hours, every few days, or less frequently.
Originally, Red Hat's enterprise product, then known as Red Hat Linux, was made freely available to anybody who wished to download it, while Red Hat made money from support.
