Cloudflare’s 1.1.1.1 often tops DNS speed charts. Yet it hands back answers to known malicious domains without hesitation. A few extra milliseconds can mean the difference between loading a clean page and fetching malware. The numbers don’t lie. Tests show clear trade-offs.
MakeUseOf tested 30 malicious domains pulled from URLhaus. Cloudflare’s plain 1.1.1.1 resolved every one of them. Average latency sat at 32.4 milliseconds. Switch to its filtered 1.1.1.2 option and latency rose to 34.7 ms. That 2.3-millisecond penalty blocked 22 out of 30 threats. (MakeUseOf, May 14, 2026)
Quad9 achieved the same 22 blocks but at 66.1 ms. Its Swiss nonprofit structure stores no IP addresses tied to queries. Nothing sits on disk for subpoenas. Google Public DNS at 8.8.8.8 clocked 41.8 ms and stopped just one malicious domain. NextDNS landed at 35.7 ms and blocked 18. Flexibility defined its edge. Users adjust filters through profiles, block lists and category sliders.
These gaps matter. DNS handles the first step for every web request. Slow or unsafe resolution ripples across browsing, apps and backend systems. Enterprise teams and power users learned this years ago. Consumers switching from ISP defaults often chase raw speed first. They miss the fuller picture.
Benchmarks Reveal More Than Milliseconds
Recent 2024 and 2025 DNSPerf data still crown Cloudflare the global leader in raw query response times across regions. MilesWeb’s analysis of those studies confirms the pattern. Cloudflare posts the lowest average times worldwide. Google follows closely for reliability and uptime. (MilesWeb, May 2026)
ElderNode’s February 2026 review echoes the same hierarchy for basic performance. Cloudflare and Google dominate speed tests. Yet both pieces stress context. No single resolver wins every scenario. Location influences real-world latency more than headline rankings suggest. ISP resolvers sometimes beat public ones simply because they sit closer on the network. (ElderNode, Feb 21, 2026)
FlashStart claimed the fastest protective DNS title in recent benchmarks with 13.45 ms average resolution. It beats Cloudflare’s 15.12 ms in that specific protective category while posting 99.95% uptime. Such specialized services target threat blocking without the broad consumer focus. They appeal to organizations that accept managed filtering.
But speed measurements capture only part of the story. DNSPerf and independent tools rarely weigh blocking accuracy, logging policies or configurability in the same ranking. A resolver that answers quickest to bad domains fails its core job for security-conscious users.
And privacy adds another layer. Cloudflare deletes full logs after 24 hours and submits to annual KPMG audits. It never sells query data. Quad9 goes further. No query data tied to individuals is stored at all. Google logs some diagnostic information even if anonymized. These differences shape risk for users in regulated industries or those wary of data requests.
NextDNS stands apart for control. Default settings block 18 malicious domains in the MakeUseOf test. Users tweak far more. Tracking domains from Google, Meta and Amazon can be dialed up or down. Parental filters, safe search and per-device profiles turn the service into a tailored gateway. Logs stay off by default. When enabled they tie to user-chosen regions and retention periods from one hour to two years.
Such options come with overhead. Setup requires a dashboard. Casual users balk at the steps. Cloudflare’s filtered variants need only an IP change. 1.1.1.2 for malware. 1.1.1.3 for malware plus adult content. Plug and play. The modest latency cost buys immediate protection.
Real-world impact shows in load times. Studies cited by MilesWeb attribute 15 to 20 percent of first-visit page delays to DNS lookups. Faster resolution shaves visible wait time. Yet a resolver that blocks threats upstream prevents worse problems. Phishing attempts drop sharply with proper DNS-layer filtering. Cisco’s 2024 Cybersecurity Threat Report noted nearly 40 percent reduction in malicious domains reached when endpoint protection includes DNS controls. CISA advisory data points to 80 percent drop in some phishing vectors.
Quad9 blocks over 100 million malicious requests daily according to its own transparency data. That volume underscores the volume of bad traffic public resolvers see. Organizations gain breathing room. Home users avoid drive-by downloads and ransomware calls home.
But not every filtered resolver fits every need. False positives happen. Legitimate domains occasionally get caught in broad threat intelligence feeds. Gaming setups sometimes suffer added latency that affects competitive play. Enterprise environments demand DNSSEC validation, ECS support or custom forwarding rules that free public options may lack.
Control D, AdGuard DNS and CleanBrowsing appear in 2026 roundups for users wanting ad blocking or family safety without NextDNS complexity. They balance features differently. Some prioritize encrypted DNS protocols. Others focus on zero-log guarantees under specific jurisdictions.
ISP defaults still dominate for most consumers. Convenience explains it. No configuration needed. Yet performance and safety often lag. Public alternatives reduce risk of visiting malicious sites by 25 percent or more per Global Cyber Alliance findings referenced in recent analyses.
So how should teams decide? Test from actual locations. Tools like DNSPerf, GRC’s benchmark or browser-based DoH testers reveal local winners. Factor in threat model. Developers chasing pure performance might stick with unfiltered Cloudflare. Security teams choose Quad9 or filtered variants. Privacy maximalists audit policies and pick non-profits. Power users configure NextDNS or Control D profiles.
Location still rules. European users often see Quad9 perform better than North American benchmarks suggest. Asian and Latin American networks flip rankings again. Anycast networks help. They don’t erase geography.
Encrypted protocols add another consideration. DNS over HTTPS or TLS hides queries from ISPs and snoops. Most major resolvers support them now. Cloudflare pushed early adoption. Adoption reduces one privacy leak but doesn’t solve upstream logging or blocking gaps.
The industry has matured. In 2018 Cloudflare launched 1.1.1.1 with privacy promises that reshaped expectations. Competitors responded with stronger guarantees and features. Benchmarks evolved. Users gained choices. Yet the core tension remains. Pure speed appeals to marketing. Real protection demands trade-offs that benchmarks rarely headline.
Recent discussions on X highlight the same split. Users praise Cloudflare for domain pricing and integrated security yet debate long-term privacy versus specialized protective services. Gaming communities test multiple resolvers to shave ping. Enterprises mix internal resolvers with public fallbacks.
Bottom line stays simple. Measure what matters for your traffic. Speed alone misleads. Combine latency data with blocking rates, privacy commitments and configuration needs. The resolver that wins on paper can lose where it counts. Pick accordingly. Test regularly. The internet’s address book updates constantly. So should your choice.
