But typically the router will be assigned the first device address in the subnet so a typical setup would be:
192.168.0.0 /26 will have
subnetwork address 192.168.0.0 /26
router address 192.168.0.1
available device addresses range 192.168.0.2 - 192.168.0.62
subnet broadcast address 192.168.0.63
192.168.0.64 /26
subnetwork address 192.168.0.64 /26
router address 192.168.0.65
available device addresses range 192.168.0.66 - 192.168.0.126
subnet broadcast address 192.168.0.127
192.168.0.128 /26
subnetwork address 192.168.0.128 /26
router address 192.168.0.129/26
available device addresses range 192.168.0.130 - 192.168.0.190
subnet broadcast address 192.168.0.191
192.168.0.192 /26
subnetwork address 192.168.0.192 /26
router address 192.168.0.193/26
available device addresses range 192.168.0.194 - 192.168.0.254
subnet broadcast address 192.168.0.255
