Azure SQL Server Firewall IP address range

Moving from Azure MySQL to SQL Server I'm required to specify a range of IP addresses that can access the Db.

Will a range of 0.0.0.0 to 255.255.255.255 be OK to enter? Is there a range of IP addresses that will give me an 'Allow All'. Its not practical for me know where requests will be coming from and be constantly updating the Database firewall rules.
