In computer networking, a broadcast address is an IP address that allows information to be sent to all machines on a given subnet rather than a specific machine. The exact notation can vary by operating system, but the standard is laid out in RFC 919. To meet Wikipedias quality standards, this article or section can be improved by converting lengthy lists to text. ...
An IP address (Internet Protocol address) is a unique number that devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP). ...

In internetworking and computer network engineering, Request for Comments (RFC) documents are a series of memoranda encompassing new research, innovations, and methodologies applicable to Internet technologies. ...
Generally, the broadcast address is found by taking the bit complement of the subnet mask and then OR-ing it bitwise with the IP address. Bit Complement The Complement of a given bit is its reverse bit. ...

In computer programming, a bitwise operation operates on one or two bit patterns or binary numerals at the level of their individual bits. ...

Example: to broadcast a packet to an entire class B subnet using a private IP address space, the broadcast address would be 172.16.255.255. Classful networking is the name given to the first round of changes to the structure of the IP address in IPv4. ...

This can be found from the subnet mask (255.255.0.0) and the IP address (eg. 172.16.48.196) - the complement of the subnet mask is 0.0.255.255, and 172.16.48.196 | 0.0.255.255 = 172.16.255.255.
A special type of IP address is the limited broadcast address 255.255.255.255. A broadcast involves delivering a message from one sender to many recipients. This broadcast is 'limited' in that it does not reach every node on the Internet, only nodes on the LAN.
Other protocols
IPX The Novell IPX protocol allows broadcast as well. When the network address is specified as FFFFFFFF, the packet is to be sent to all the networks available. When the target node address is specified as FFFFFFFFFFFF, the packet is intended to be received by all the computers in the network. Internetwork Packet Exchange (IPX) is at the Network layer of the OSI model and is part of the IPX/SPX protocol stack. ...
Ethernet layer Broadcast is possible also on the underlying data link layer. Ethernet frames can be addressed to every computer on a given LAN segment if they are addressed to MAC address FF:FF:FF:FF:FF:FF. Ethernet frames that contain IP broadcast packages are usually sent to this address. ARP typically uses segment-wide broadcast for its queries.
