To indicate what IP addresses should be permitted or denied in access control lists (ACLs). A wildcard mask can be thought of as an inverted subnet mask. For example, a subnet mask of 255.255.255.0 (11111111.11111111.11111111.00000000 2) inverts to a wildcard mask of 0.0.0.255 (00000000.00000000.00000000.11111111 2).
Reserved for future use (formerly "Class E" [5]). 255.255.255.255 is reserved for "limited broadcast" destination address. [ 6 ] [ 7 ] List of assigned /8 blocks to commercial organisations
A special definition exists for the IP address 255.255.255.255. It is the broadcast address of the zero network or 0.0.0.0, which in Internet Protocol standards stands for this network, i.e. the local network. Transmission to this address is limited by definition, in that it is never forwarded by the routers connecting the local network to ...
The 232.0.0.0 / 8 (IPv4) and ff3x:: / 32 (IPv6) blocks are reserved for use by source-specific multicast. GLOP [13] The 233.0.0.0 / 8 range was originally assigned as an experimental, public statically-assigned multicast address space for publishers and Internet service providers that wished to source content on the Internet. [14]
All receivers capture the network packet. The address 255.255.255.255 is used for network broadcast. In addition, a more limited directed broadcast uses the all-ones host address with the network prefix. For example, the destination address used for directed broadcast to devices on the network 192.0.2.0 / 24 is 192.0.2.255. [24]
The columns Network destination and Netmask together describe the Network identifier as mentioned earlier. For example, destination 192.168.0.0 and netmask 255.255.255.0 can be written as 192.168.0.0/24. The Gateway column contains the same information as the Next hop, i.e. it points to the gateway through which the network can be reached.

The DHCP client broadcasts a DHCPDISCOVER message on the network subnet using the destination address 255.255.255.255 (limited broadcast) or the specific subnet broadcast address (directed broadcast). A DHCP client may also request an IP address in the DHCPDISCOVER, which the server may take into account when selecting an address to offer.
