A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [1] In data communication, a physical network node may either be data communication equipment (such as a modem , hub , bridge or switch ) or data terminal equipment (such ...
Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
IP provides re-ordering of fragments received out of order. [19] An IPv6 network does not perform fragmentation in network elements, but requires end hosts and higher-layer protocols to avoid exceeding the path MTU. [20] The Transmission Control Protocol (TCP) is an example of a protocol that adjusts its segment size to be smaller than the MTU.
Any type of IP address that changes is called a dynamic IP address. In home networks, the ISP usually assigns a dynamic IP. If an ISP gave a home network an unchanging address, it is more likely to be abused by customers who host websites from home, or by hackers who can try the same IP address over and over until they breach a network.

In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. It serves as the default gateway for all network devices. Enterprise network systems may require many internal network segments. A device wishing to communicate with a host on the public ...
These suggestions are designed to help with broadband connections only. If you don't have broadband, you'll need to try other steps to fix problems with a dial-up internet connection.
When packets are sent over a network, the destination IP address is examined. If the destination IP is outside of the network, then the packet goes to the gateway for transmission outside of the network. The gateway is on the same network as end devices. The gateway address must have the same subnet mask as host devices. Each host on the ...
