The rise of “Pi-hole in the cloud”—hosted DNS resolvers that block ads, trackers, telemetry, and phishing across every device without maintaining local home hardware—has centered around three major contenders in 2026: AdGuard DNS, NextDNS, and Control D.
While all three filter unwanted traffic at the DNS layer, their architectural upgrades across 2025 and 2026 carved out distinct strengths. AdGuard DNS rolled out post-quantum cryptography (PQC) across DoH, DoT, and DoQ and expanded enterprise MDM deployment for Android and iOS. NextDNS retained its crown for deep per-device analytics, massive third-party blocklist libraries, and selectable log storage jurisdictions (such as Switzerland or the EU). Control D, backed by Windscribe’s global network, surged among power users by combining low-latency filtering with VPN-free per-domain traffic redirection.
In this 2026 comparison, we evaluate Anycast latency, DNS over QUIC (DoQ) performance, privacy jurisdictions, free tier limits, and how to benchmark filtered DNS resolvers accurately on your own connection.

No (requires free profile ID) | Yes (76.76.2.0 unfiltered / 76.76.2.2 filtered) |
| Free Dashboard Tier | Up to 300k queries/mo (5 devices) | Up to 300k queries/mo (unlimited devices) | Public resolvers are free; custom dashboard is paid (with trial) |
| Supported Transports | UDP, DoT, DoH, DoQ, HTTP/3, DNSCrypt | UDP, DoT, DoH, DoQ, HTTP/3 | UDP, DoT, DoH, DoQ, HTTP/3 |
| Standout 2026 Advantage | Post-quantum encryption (PQC) on DoQ/DoH/DoT + native AdGuard lists | Deep blocklist library (OISD, Hagezi) + Swiss log storage option | Per-domain proxy redirection + ultra-fast Anycast routing |
| Block Response Behavior | Returns 0.0.0.0, NXDOMAIN, or custom rule response |
0.0.0.0 or NXDOMAIN + optional block page |
0.0.0.0 / NXDOMAIN or transparent proxy redirect |
1. Anycast Speed and the DNS over QUIC (DoQ) Advantage
Unlike pure unfiltered resolvers such as 1.1.1.1 or 8.8.8.8, cloud-filtering resolvers evaluate each query against hundreds of thousands of domain rules before answering. In 2026, that in-memory rule evaluation takes only microseconds; what actually determines real-world speed is Anycast point-of-presence (PoP) proximity and encrypted transport efficiency.
Why DoQ and DoH3 Matter on Mobile
All three providers support DNS over QUIC (DoQ, RFC 9250) and DNS over HTTP/3 (DoH3). That matters enormously if you configure encrypted DNS on a smartphone or laptop:
- Classic DoT (port 853 over TCP): a single lost packet on congested Wi-Fi or cellular links stalls every concurrent DNS lookup sharing that TCP stream until retransmission completes.
- DoQ (port 853 over QUIC/UDP): each lookup runs in an independent stream, transport + TLS 1.3 negotiation completes in 1 RTT (or 0-RTT on resumption), and connection migration keeps your session alive when switching from Wi-Fi to 5G.
AdGuard DNS was the earliest champion of DoQ and, across its 2025–2026 DnsLibs updates, integrated post-quantum cryptography (PQC) into its encrypted DNS endpoints to guard against harvest-now, decrypt-later threats. Meanwhile, NextDNS and Control D routinely trade first place in raw Anycast latency across North America, Europe, and South America thanks to dense regional peering.

2. Filtering Depth and Blocklist Ecosystems
Although all three block ads, trackers, and phishing domains, their day-to-day workflows target different users:
- AdGuard DNS: excels at clean, low-maintenance filtering. Because AdGuard maintains its own flagship filter lists, its account-free public endpoint (
dns.adguard-dns.comor94.140.14.14/94.140.15.15) blocks ads and trackers out of the box with minimal false positives. Its cloud dashboard adds scheduled parental controls, custom Adblock-syntax rules, and third-party list toggles. - NextDNS: remains the favorite for network enthusiasts who want granular control. Within seconds you can combine community gold-standard lists like OISD, Hagezi Multi Pro, and StevenBlack, block Newly Registered Domains (NRDs) younger than 30 days, and strip native OS telemetry (Windows, Apple, Samsung, Xiaomi).
- Control D: goes beyond blocking by acting as a programmable traffic router. In addition to curated category filters (Ads, IoT telemetry, Malware, Social), Control D lets paying users redirect specific domains or streaming services through proxy exit nodes in dozens of countries without running a system-wide VPN.
3. Privacy, Jurisdiction, and Log Retention
When using a customizable cloud DNS service, you control whether query logs are stored—but corporate jurisdiction and defaults still matter:
- AdGuard DNS (Cyprus / European Union): operates under strict EU GDPR data protection rules. Its public resolvers do not tie queries to personal accounts, and cloud dashboard users can disable query logging entirely or set short retention windows.
- NextDNS (US with selectable storage region): while incorporated in Delaware (US), NextDNS lets you choose where your logs are physically stored—Switzerland, the European Union, the United States, or the United Kingdom—or disable disk logging completely.
- Control D (Canada): built by the team behind Windscribe, Control D enforces a strict no-logging baseline by default; real-time analytics streaming is only active while you explicitly enable it in the dashboard for troubleshooting.

4. How to Benchmark AdGuard, NextDNS, and Control D Accurately
Testing filtered DNS servers requires a methodical approach so security and ad-blocking policies do not skew latency numbers:
- Never benchmark availability with ad domains: when a filtered resolver blocks a tracker, it intentionally returns
0.0.0.0orNXDOMAIN. Always run performance benchmarks against neutral domains so policy blocks are not miscounted as packet loss. - Compare public endpoints directly on your line: in the DNS Benchmark app, you can test AdGuard’s public resolvers (
94.140.14.14filtered and94.140.14.140unfiltered) and Control D’s public resolvers (76.76.2.0unfiltered and76.76.2.2filtered) side by side with Cloudflare (1.1.1.1) and Quad9 (9.9.9.9). - Watch P95 latency and jitter: a well-peered cloud resolver should deliver low jitter (< 5 ms on fiber) and 100% reliability on neutral lookups.

2026 Verdict: Which Filtered DNS Should You Choose?
- Choose AdGuard DNS if you want a “set-and-forget” blocker (including account-free public IPs and DoT/DoQ hostnames), prefer EU/GDPR jurisdiction, and want cutting-edge DoQ with post-quantum encryption.
- Choose NextDNS if you want the richest free analytics dashboard to inspect exactly what your devices query, combine lists like Hagezi and OISD, and store logs in Switzerland.
- Choose Control D if you are a power user seeking top-tier Anycast speed, fast account-free public resolvers (
76.76.2.2), or per-domain proxy traffic redirection.
