an IPv4 address can end in 255 without being a broadcast address

. For it to be a broadcast address, all bits in the host part need to be ones. … 0.0/17 network is not a broadcast address, since the netmask is 255.255.

Is 255.255 255.255 IP address valid?

In general, using 255.255.

255.255 is a bad idea

the number of bits that are fixed (would not change) in a range of addresses of a network

Why is IPv4 32-bit?

Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because

of the growth of the Internet and the depletion of available IPv4 addresses

, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998.
