THE DEFINITIONS
Open a term for a plain-language explanation, a technical explanation, and a practical example.
Border Gateway Protocol is the routing protocol used by autonomous systems to exchange reachability information across the Internet.
Carrier-grade NAT is address and port translation operated by an internet provider so multiple customers can share public IPv4 addresses.
Manipulation of DNS information so a name resolves to an unintended destination.
An event or attack that prevents legitimate users from accessing a service.
A distributed system that translates domain names into DNS records such as IP addresses.
Dynamic Host Configuration Protocol automatically supplies network settings such as an IP address, subnet information, gateway, and DNS servers to a device.
A numeric address used to identify a network interface in Internet Protocol communication.
An intrusion prevention system monitors activity for signs of attack and can automatically block or interrupt traffic that matches its detection logic.
Network access control checks whether a device or user is allowed to join a network and may assign access based on identity or device state.
Network address translation changes IP address information as packets cross a network boundary, often letting multiple private devices share public connectivity.
Dividing a network into zones with controlled communication between them.
Packet inspection is the examination of network packet headers, metadata, or payloads to classify traffic and apply monitoring or security policy.
A private IP address is an address from a range reserved for use within private networks rather than routing directly on the public Internet.
A proxy server is an intermediary selected by a client to make requests to another service on the client's behalf.
A public IP address is an Internet address intended for globally reachable routing, subject to network policy and address allocation.
A reverse proxy is an intermediary that receives client requests as the public-facing endpoint and forwards them to one or more backend services.
Transmission Control Protocol is a connection-oriented transport protocol that provides an ordered, reliable byte stream between applications.
User Datagram Protocol is a lightweight transport protocol that sends datagrams between application ports without guaranteeing delivery or ordering.
A virtual local area network is a logical grouping of network ports and traffic within a bridged network, independent of physical cabling.
Technology that creates an encrypted network tunnel between endpoints over another network.
