3.1 cm (1.2 in) (d)[2] Mass. 301g (BT Home Hub 5) [2] The BT Smart Hub (formerly BT Home Hub) is a family of wireless residential gateway router modems distributed by BT for use with their own products and services and those of wholesale resellers (i.e. LLUs) but not with other Internet services. Since v 5 Home/Smart Hubs support the faster Wi ...
A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (layer 3 for OSI ...
The O2 Wireless Box IV (available to new "O2 Premium" customers during 2010) is a rebadged Thomson SpeedTouch TG587nv2, which has additional support for 802.11n, dual antennas, and also has two USB ports for connection to an external USB hard disk for sharing of files direct to the wifi or Ethernet network, or printer sharing.
A residential gateway is a small consumer-grade gateway which bridges network access between connected local area network (LAN) hosts to a wide area network (WAN) (such as the Internet) via a modem, or directly connects to a WAN (as in EttH), while routing. The WAN is a larger computer network, generally operated by an Internet service provider.
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 ...
ICMP Router Discovery Protocol. In computer networking, the ICMP Internet Router Discovery Protocol (IRDP), also called the Internet Router Discovery Protocol, [1] is a protocol for computer hosts to discover the presence and location of routers on their IPv4 local area network. Router discovery is useful for accessing computer systems on other ...
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 ...
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 ...
