A Service (SRV) record in DNS is used to specify hostnames and port numbers for specific services, such as VoIP, email, or game servers. It allows service discovery and load balancing across multiple servers.

A tool used to determine the maximum data transfer rate of a network by considering bandwidth, latency, and packet loss. Useful for optimizing streaming performance and server capacity planning.

The process of estimating total data transfer based on factors like bitrate, number of users, and streaming duration. This helps in planning CDN resources and avoiding overage charges.

A security feature used in CDN and web applications to allow or block specific IP addresses or ranges. It helps restrict access, prevent attacks, and ensure compliance with regional regulations.

VLC Media Player supports live and on-demand streaming through its “Open Network Stream” option. Users can input a streaming URL (RTSP, HLS, etc.) to play video content from online sources.

CNAME (Canonical Name): A DNS record that maps an alias domain name to the true (canonical) domain. Useful for pointing multiple subdomains to a primary domain. Alias Record: Similar to CNAME but works at the root level, allowing domains to point to services like CDNs or load balancers while preserving the original domain name.

The SOA record is a crucial DNS record that specifies authoritative information about a domain, such as the primary name server, contact email, domain serial number, and DNS refresh intervals. It is the first record in a DNS zone file.

Another term for the Start of Authority (SOA) record, which defines key settings for domain management in DNS.

A video file format used by Adobe Flash, similar to MP4 but optimized for streaming.

The process of determining the data transfer required for streaming or hosting content, often based on bitrate, audience size, and duration.
