In short, no. There are very few cases where a static IP address is needed and using them can often cause far more issues than they solve. For most residential networks, the default settings of your router and dCS device are correct and do not need to be changed.
If you do need your unit to be on a specific IP address (such as when using a control system like Control4 or Crestron), it is normally better practice to set a ‘Reserved Dynamic’ address within the settings of the router. This avoids several potential issues and means if you move your unit onto another network or something about your network environment changes, the unit won’t become stuck outside of the network’s IP range and disappear.
