Here is the translated text into American English:
The 1.1.1.1 DNS resolution service from Cloudflare, launched on April 1, 2018, has grown significantly over the years, currently managing an average of 1.9 trillion daily queries from 250 locations worldwide. As a high-performance, privacy-focused DNS service, 1.1.1.1 has become a key component of Internet infrastructure. Analyzing this traffic allows Cloudflare Radar to provide unique insights into network activity, beyond simple web traffic trends.
Launch of the DNS Page on Cloudflare Radar
Building on previous analysis of DNS resolution service data, Cloudflare has now introduced a dedicated DNS page on Cloudflare Radar. This new section enhances visibility into DNS trends, covering traffic at a global, location, and Autonomous System (ASN) level. The analysis also includes protocol usage, query and response characteristics, and DNSSEC adoption.
This feature complements previous initiatives, such as Cloudflare’s participation in Project AS112 (since December 2022) and the launch of AS112 traffic statistics in March 2023. The goal is to provide deeper insights into DNS activity across different networks and geographic regions.
DNS Traffic Trends and Metrics
As part of the Cloudflare Radar analysis, the new DNS page offers:
- Normalized query volume: Displays global traffic trends and comparisons over different time periods.
- ASN-level information: Lists the networks generating the most DNS queries in specific regions.
- Analysis of country code top-level domains (ccTLDs): Tracking query volumes for domains like .ai (Anguilla), .io (British Indian Ocean Territory), .fm (Micronesia), and .co (Colombia).
- Detection of Internet outages and blocks: Aids in identifying disruptions by observing sudden drops in query volume, such as the reported blocking of 1.1.1.1 by providers in Venezuela.
Query and Response Analysis
Beyond traffic, Cloudflare’s DNS page delves into the characteristics of queries and responses:
- Transport protocol distribution: Monitoring the adoption of UDP (86.6%), DoT (9.6%), TCP (2.0%), and DoH (1.7%) according to recent global statistics.
- Response code analysis: Highlights the most common DNS responses, including NOERROR (successful queries) and NXDOMAIN (non-existent domains).
- Cache efficiency: Shows how often DNS responses come from the cache instead of requiring new lookups.
- Time-to-live (TTL) distribution: Examines how long DNS records remain cached, providing insights into domain stability.
DNS Security and DNSSEC Adoption
Cloudflare continues to prioritize privacy and security in its DNS operations. The new Radar insights include:
- DNSSEC adoption rates: Identifies whether queries come from DNSSEC-capable clients and assesses the percentage of correctly signed domains for validation.
- End-to-end security metrics: Measures the fraction of DNS queries that are encrypted and protected from tampering.
Access and Sharing of DNS Information
The new DNS page on Cloudflare Radar is interactive and provides access to detailed analytics through:
- API and Data Explorer: Users can filter and analyze DNS trends by different networks, locations, and time periods.
- Embeddable charts: DNS analyses can be shared on blogs, dashboards, and reports.
- Social Media Sharing: Users can tag Cloudflare Radar (@CloudflareRadar) to share information on Twitter, Mastodon, and Bluesky.
Conclusion
DNS is a fundamental component of the Internet, and the new DNS page on Cloudflare Radar provides valuable transparency regarding its global impact. By offering detailed analytics, security insights, and real-time monitoring, Cloudflare continues its mission to make the Internet more open, secure, and efficient. Those interested in enhancing their online experience can explore Cloudflare’s 1.1.1.1 DNS resolution service and the WARP app for added security and performance.
