No, whatever it is at the time. The IP address will change if the AVR is disconnected for a seriously long time or if you change the router, but you can find the address if you download the Yamaha control app to your tablet and click on the gear on the display and then, use the Advanced Settings button.
Worst case, log into the router and look at the connected devices list. Once the AVR is found, it (the AVR) can be changed to static inside of the menu.
BTW- for anyone who likes other brands, Denon removed IP menu access years ago and they don't seem to have any plans to return it. That really sucks because having that really saves a lot of time, especially for dealers and integrators who have the luxury of using 'cookie cutter' configurations because the configuration could be saved to a thumb drive and used at the office or sent to the job site with the installers, who would then load it at the time of commissioning. Yamaha kept this and it really makes life better.
