The initial value amounts to a maximum of 255. A ping flood is a DOS attack from like 1995, these days it requires a heavily coordinated attack to bring down a normal broadband connection. The -4 option forces the use of IPv4 and is only employed if the recipient is addressed via the hostname. This is especially the case in large networks, where devices are constantly changing and the manual assignment of IP addresses is a never-ending task.
