Explanation

Windows TCP/IP settings include an 'Alternate Configuration' tab. The correct approach is to set the primary adapter configuration to 'Obtain an IP address automatically' (DHCP) for use at home, and enter the static work IP address in the Alternate Configuration tab. When the laptop is at work and a DHCP server does not respond (or is not present on that segment), Windows automatically falls back to the static alternate configuration. When the laptop is at home, DHCP responds and assigns an address normally. This eliminates the need to manually change settings each day. Installing a second NIC, using a VPN just for IP settings, or splitting by connection type are all more complex or impractical solutions.
