How to Release and Renew IP Address on Windows, Mac, Linux

Situatie

Release/Renew IP address is a procedure meant to solve network connectivity issues related to cached IP information. It can be done via Command Line on Windows or System Preferences on Mac OS. Release and Renew IP address means giving up the lease of DHCP IP address of the host computer and making a request for a new IP address. First of all, the ipconfig /release command is used to give up current IP lease and send the server a DHCP alert to mark the old IP address as available.
