- The DNS is critical to the Internet, serving as a stable endpoint identifier and common referential framework.
- Centrality refers to market dominance, often arising from early-comer advantage, as seen in Internet search.
- DNS registration shows low concentration; GoDaddy has 10.9% market share, indicating no centralization.
- Recursive DNS resolution is decentralized, with 65-80% of users relying on ISP resolvers, and open resolvers (like Google and Cloudflare) holding 21.7% collectively.
- Open recursive resolver market is centralized, with Google dominating, but ISP services balance this globally.
- Authoritative DNS server hosting shows consolidation, with the top 10 providers handling 67% of queries, and all top entities based in the US.
- Geopolitical centrality is evident, as US entities dominate authoritative server hosting.
- The DNS resolution market is not centralized overall, but concerns exist for authoritative services and specific national markets.
- Economic aspects of DNS resolution challenge monopoly risks, as services are generally free to users.
