Nowadays, anyone setting up a network will generally use the Dynamic Host Configuration Protocol (DHCP) to assign IP addresses. Connecting devices are therefore integrated into the home network without any user input through the automated assignment of IP addresses. If you encounter any problems when using this type of dynamic network configuration or if you want to manually modify the address assignment for other reasons, ipconfig can help.
You can manage and modify DHCP routines with ipconfig. For example, you can release and renew an IP address if it was assigned incorrectly by the DHCP server during the automated assignment process or if it is not what the user intended. You can also find information about DHCP leases and therefore about when a DHCP address was assigned and how long it will be valid. IP addresses are not permanently assigned by DHCP; they are only valid for a specific period of time. Servers and clients can terminate, modify, or renew this assignment at any time.
