TCP/IP defines the addresses 192.168.4.0 (network ID address) and 192.168.4.255 (broadcast IP address). The office's hosts send packets to addresses within this range directly, by resolving the destination IP address into a MAC address with the Address Resolution Protocol (ARP) sequence and then encapsulates the IP packet into a MAC frame ...
Note that using a reserved IPv4 address, such as those provided by RFC 1918, is undefined, since these networks are disallowed from being routed on the public Internet. For example, using 192.168.1.1 as the router's WAN address would be invalid since a return packet would not be able to determine the destination IPv4 address of the actual sender.
In Internet networking, a private network is a computer network that uses a private address space of IP addresses. These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments. Both the IPv4 and the IPv6 specifications define private IP address ranges.

IPv6 address. An Internet Protocol version 6 address (IPv6 address) is a numeric label that is used to identify and locate a network interface of a computer or a network node participating in a computer network using IPv6. IP addresses are included in the packet header to indicate the source and the destination of each packet.
Wireless security. Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network. The most ...
To obtain the broadcast address, the host bits get set to all 1's, while the network address prefix bits remain intact. 1. Network IP Address 10101100.00010000.00000000.00000000: 172.16.0.0 2. Subnet Mask, or just "Netmask" for short (The '/12' in the IP address in this case means only the left-most 12 bits are 1s, as shown here.
The Freifunk-Initiative installing Wi‑Fi antennas in Berlin-Kreuzberg in 2013.. Wireless community networks or wireless community projects or simply community networks, are non-centralized, self-managed and collaborative networks organized in a grassroots fashion by communities, non-governmental organizations and cooperatives in order to provide a viable alternative to municipal wireless ...
Network address translation. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1] The technique was originally used to bypass the need to assign a new address to every host when ...
