Link-local address. In computer networking, a link-local address is a network address that is valid only for communications on a local link, i.e. within a subnetwork that a host is connected to. Link-local addresses are typically assigned automatically through a process known as link-local address autoconfiguration, [1] also known as auto-IP ...

Network-attached storage (NAS) is a file-level (as opposed to block-level storage) computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term "NAS" can refer to both the technology and systems involved, or a specialized device built for such functionality (as unlike ...
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1][2] IP addresses serve two main functions: network interface identification, and location addressing. Internet Protocol version 4 (IPv4) defines an IP ...
Classless Inter-Domain Routing (CIDR / ˈsaɪdər, ˈsɪ -/) is a method for allocating IP addresses for IP routing. The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet. Its goal was to slow the growth of routing tables on routers across the Internet, and ...
The RADIUS server searches through its resources and finds that the credentials are valid and notifies the NAS that it should grant the access. The NAS then grants the user access to the Internet. Another use of a NAS would be in voice over IP (VoIP). However, instead of using a username and password, many times a phone number or IP Address are ...
Network address translation between a private network and the Internet. 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 ...
