No it is not required.

cisco says,

The IP address configured on the router interface is automatically excluded from the DHCP address pool.

More details are here (cisco official site)


No, the router is smart enough to not hand out is own IP address.


No need to include in excluded address . Instead of this include mentioned command in DHCP pool . This command will avoid allocating this ip address to hosts

Router(config) #IP dhcp default gateway
