Glossary Terms
Anycast
Anycast advertises the same IP address from multiple locations and uses BGP routing to send traffic to the nearest or best network point.
Bandwidth
Bandwidth is the maximum data capacity a connection can carry per second; it does not define perceived speed by itself.
BGP (Border Gateway Protocol)
BGP is the internet routing protocol where autonomous systems announce which IP prefixes can be reached through which paths.
CNAME (Canonical Name Record)
A CNAME record maps one domain name to another as an alias, commonly used for subdomains, SaaS apps, and CDN endpoints.
DKIM (DomainKeys Identified Mail)
DKIM adds a cryptographic signature to email so receiving servers can verify that a domain authorized and preserved the message.
DMARC (Domain-based Message Authentication, Reporting, and Conformance)
DMARC combines SPF and DKIM results with domain policy and reporting so email senders can reduce spoofing and phishing risk.
DNS (Domain Name System)
DNS maps readable domain names to IP addresses so browsers, email servers, and APIs can reach the right destination without hard-coded numbers.
DNS Propagation
DNS propagation is the period during which a changed DNS record spreads through recursive resolvers and caches around the world.
DNS Record
A DNS record is an instruction that tells a domain where to send web traffic, email, verification checks, or other internet requests.
Firewall
A firewall filters traffic between devices and networks using rules, allowing approved connections while blocking suspicious or unauthorized access.
FTP (File Transfer Protocol)
FTP is an older protocol for transferring files over a network; because it lacks encryption, SFTP or HTTPS is usually preferred today.
HTTP/2
HTTP/2 speeds up web pages and API responses by using multiple streams and compressed headers over a single connection.
HTTP/3
HTTP/3 runs HTTP semantics over QUIC and UDP, reducing connection setup time and limiting the impact of packet loss.
IMAP (Internet Message Access Protocol)
IMAP keeps email on the server and synchronizes folders, read state, flags, and mailbox changes across multiple devices.
IoT (Internet of Things)
IoT connects sensors, machines, and devices to the internet so they can collect data, share status, and be managed remotely.
IP Address
An IP address is a numeric label used to identify devices on a network and route data packets to the correct destination.
IPv6
IPv6 is the IP version with 128-bit addressing, expanding beyond IPv4 limits for broader and more efficient modern networking.
Latency
Latency is the time it takes for a network request to travel from source to destination and back; low latency is key to performance.
MQTT
MQTT is a lightweight publish-subscribe protocol that lets IoT devices exchange topic-based messages through a broker.
Mutual TLS (mTLS)
Mutual TLS verifies both client and server certificates during a TLS connection, reducing trust in network location alone.
NAT (Network Address Translation)
NAT translates private network addresses to public addresses or ports, allowing local devices to communicate across the internet.
NAT64
NAT64 translates traffic so IPv6-only clients can reach IPv4 services, usually together with DNS64 in transition networks.
QUIC Protocol
QUIC is a modern UDP-based transport protocol with built-in TLS 1.3 encryption that gives HTTP/3 faster connection setup and recovery.
SFTP (SSH File Transfer Protocol)
SFTP transfers files over an SSH connection through encrypted command and data channels, supporting key-based authentication.
SMTP (Simple Mail Transfer Protocol)
SMTP is the standard transfer protocol that sends email from clients to mail servers and relays it between servers toward the recipient domain.
SPF (Sender Policy Framework)
SPF is an email authentication control that publishes approved sending servers in DNS, helping receivers spot spoofed domain mail.
SSH (Secure Shell)
SSH is a network protocol for encrypted remote login, command execution, and secure file transfer on remote servers.
Subnet
A subnet divides an IP address range into smaller network sections for routing, security boundaries, and address management.
TCP/IP
TCP/IP is the protocol suite that defines addressing, packet routing, and reliable data transfer across internet-connected networks.
TTL (Time to Live)
TTL defines how long DNS records or cache entries are considered valid before they must be requested or generated again.
UDP (User Datagram Protocol)
UDP sends datagrams without establishing a connection, choosing low latency and low protocol overhead over delivery guarantees.
VLAN
A VLAN separates devices into logical network groups on shared hardware, isolating traffic and tightening access control.
VPN (Virtual Private Network)
A VPN creates an encrypted tunnel between a device and a target network, protecting traffic and enabling private access.
WebRTC
WebRTC is a real-time communication standard for plugin-free audio, video, and data channels between browsers and mobile apps.
