Installing router
If you have an older router it’s almost a guarantee that your router uses the 192.168.0.0 block, much less commonly the 172.16.0.0 block, and very rarely the 10.0.0.0 block. Most newer routers, however, ship with the 10.0.0.0 block set as their default private network address space. From a technical standpoint, that’s a reasonable change.
