The Domain Name System (DNS) is a hierarchical, distributed naming system that translates human-readable domain names into the numerical addresses used to locate computers and services on a network. It is a foundational component of the Internet, resolving names through a delegated tree of authoritative servers, recursive resolvers and caching layers. DNS also carries service, security and routing metadata that many higher-level protocols depend upon.
Overview
- Domain Name System is situated within the infrastructure domain and is defined as a subclass of Networking Infrastructure.
- It connects to the wider knowledge graph through 17 typed relations spanning structural, functional and contrastive predicates.
- As a mature concept, it represents established knowledge with stable terminology and well-understood boundaries.
Key aspects
- Relationship to Networking Infrastructure situates this concept within its operational and conceptual context.
- Relationship to DNS situates this concept within its operational and conceptual context.
- Relationship to Network Protocol situates this concept within its operational and conceptual context.
- Relationship to Name Resolution situates this concept within its operational and conceptual context.
- Relationship to Service Discovery situates this concept within its operational and conceptual context.
Mechanisms
- The concept is realised through its constituent parts and the standards, methods and dependencies enumerated in its relations.
- It both requires upstream capabilities and enables downstream capabilities, forming part of a directed chain of dependencies in the graph.
Applications
- Practical use of Domain Name System appears wherever its enabled and supported concepts are deployed.
- It is referenced by existing classes in the graph, anchoring those edges to a defined, rooted node.
