Explore key networking, router, and switch terms to get familiar with essential concepts and make the most of Cudy products.
Networking¶
Internet
The logical interface representing the router’s upstream connection to a public network, typically an ISP, responsible for IP address acquisition, routing, and default gateway assignment.
WAN
(Wide Area Network) A network interface that connects the local routing domain to external networks across large geographic distances, serving as the primary ingress and egress point for Internet traffic.
DHCP
A method where the ISP's server automatically assigns an IP address to your router upon connection.
Router¶
DDNS
(Dynamic DNS) Maps a static domain name to a changing public IP address, allowing remote access to your network.
Firewall
A security system that monitors and controls incoming and outgoing network traffic based on predetermined rules.
IPv6
(Internet Protocol Version 6) A network-layer protocol designed to replace IPv4, providing a vastly expanded address space, simplified header structure, and native support for auto-configuration.
Switch¶
Broadcast
A network transmission method where data is sent from one sender to all devices on the same local network segment.
Duplex
Refers to the data transmission mode. Half-duplex allows one-way communication at a time; Full-duplex allows simultaneous two-way communication.
Uplink
A port, often with higher speed, used to connect a local switch to a core switch, router, or the wider network.
