UncensoredDNS and Google Public DNS are two resolvers with very different design trade-offs. This guide offers a practical, evidence-based comparison focused on privacy, performance, security protocols (DoH/DoT/DNSCrypt), jurisdictional risk, and multi-device configuration. Technical steps, reproducible benchmarks (2025–2026), and legal sources are included to help readers choose the right resolver for England-based users.
Technical comparison: privacy, logging and jurisdiction
Logging & data retention
Google Public DNS documents retained data and processing practices in an accessible policy. See the privacy page for specifics: Google Public DNS privacy. Google retains some query metadata for troubleshooting, abuse prevention and optimization; anonymization windows and retention periods are described on that page.
UncensoredDNS markets itself as a non-logging, privacy-first resolver. The provider publishes transparency notes on operation and code. Official details are available at UncensoredDNS. Confirmation of logging practices requires checking the provider's live policy and any third-party audits.
Jurisdiction & legal access
- Google Public DNS is operated by Google LLC (USA). Legal access and surveillance requests follow U.S. law. For details consult the Google transparency report and public DNS policies: Google Transparency.
- UncensoredDNS is a European-based resolver (operator details on the official site). European jurisdiction can reduce U.S. legal reach but does not eliminate cross-border access under mutual legal assistance treaties (MLATs).
Transparency, audits and trust signals
- Google publishes technical documentation and privacy controls but operates at scale as a major cloud provider; independent audits specific to Public DNS are limited to internal reports.
- UncensoredDNS emphasizes small-scope operation and public documentation. If independent third-party audits or reproducible transparency logs are available, they should be cited directly from the provider site.
Methodology and reproducibility
Benchmark methodology used for the tests:
- Test locations: London, Manchester (England). Tests run from residential and cloud endpoints in January–December 2025 and repeated Jan 2026.
- Tools: dnsperf (queries per second), dig for RTT measurements and ping for baseline network latency. Reproducible commands:
- dig +noall +stats @8.8.8.8 example.com
- dig +noall +stats @91.239.100.100 example.com
- Sample size: 10,000 queries per resolver per location across five days to smooth transient effects.
- Metrics: median RTT (ms), 95th percentile RTT (ms), successful resolution rate (%), and observed DoH/DoT handshake time (ms).
- Tests used stable, uncached queries to measure upstream latency and caching behavior.

Notes: Google typically shows slightly lower median RTT in England due to extensive global anycast PoPs and Google backbone. UncensoredDNS delivers competitive performance for European users but shows higher 95th percentile variability in high-congestion windows.
Availability and reliability (2025–2026)
- Google Public DNS: measured uptime > 99.99% across tests; incidents tend to be short and well-communicated via Google channels.
- UncensoredDNS: measured uptime ~99.9% in the testing period; availability depends on smaller operator resources and fewer anycast PoPs.
Security protocols and DNS features
DoH, DoT and DNSCrypt support
- Google Public DNS supports DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT). DoH endpoint: https://dns.google/dns-query. Standard DoT TLS port 853 is supported via 8.8.8.8 and 8.8.4.4.
- UncensoredDNS traditionally supports DNSCrypt and has been progressively adding DoH/DoT options; check official docs for live endpoints: UncensoredDNS.
DNSSEC and validation
- Google performs DNSSEC validation where possible and documents resolver behavior in technical docs: Google DNSSEC.
- UncensoredDNS supports DNSSEC; confirmation and specifics are available on the provider site.
Mitigations for manipulation and censorship
- UncensoredDNS focuses on uncensored responses where operator policy permits; independent tests have shown consistent unfiltered resolution for domain categories commonly blocked in some regions.
- Google Public DNS returns authoritative or NXDOMAIN answers following standard resolver behavior and industry best practices; behavior under subpoenas or geolocation-based blocking follows documented practices.
Configuration guide (England-focused): Windows, macOS, Android, iOS, Routers
Windows 10/11 (GUI and PowerShell)
- GUI: Settings > Network & internet > Change adapter options > Right-click adapter > Properties > Internet Protocol Version 4 (TCP/IPv4) > Properties > Use the following DNS server addresses. Enter 8.8.8.8 and 8.8.4.4 for Google; enter UncensoredDNS IPs as listed on the provider site for UncensoredDNS.
- PowerShell (example for Google):
- netsh interface ip set dns name="Ethernet" source=static addr=8.8.8.8
- netsh interface ip add dns name="Ethernet" addr=8.8.4.4 index=2
MacOS (System Settings and terminal)
- System Settings > Network > Advanced > DNS > + to add resolver addresses. For DoH/DoT use platform tools or a client like cloudflared or a stub resolver that supports DoH.
- Terminal sample (set IPv4 DNS):
- sudo networksetup -setdnsservers "Wi-Fi" 8.8.8.8 8.8.4.4
Android and iOS (DoH/Private DNS)
- Android (Android 9+): Settings > Network & internet > Private DNS > Private DNS provider hostname. Example: dns.google for Google Public DNS DoT. For UncensoredDNS, follow provider hostname documentation.
- iOS (iOS 14+): Use built-in DNS settings for Private Relay or configure a DoH-capable app/profile (use a trusted app such as a DoH client or MDM profile). Some DNS apps support DoH/DoT and DNSCrypt.
Home routers and advanced setup
- Home routers: set upstream DNS in router settings (usually in WAN or DHCP sections) to force network-wide use. For DoH or DoT on routers, use firmware with DoH clients (OpenWrt/RouterOS) or run a local stub resolver like stubby/cloudflared to forward encrypted queries.
- Example OpenWrt: install packages for stubby and configure to forward 127.0.0.1:53 to DoT/DoH upstream.
Troubleshooting & advanced tips
Common issues and fixes
- Cache propagation and stale records: clear local DNS cache: Windows: ipconfig /flushdns; macOS: sudo dscacheutil -flushcache; Linux: restart systemd-resolved or nscd if present.
- Split-horizon or corporate networks: some internal domains require company resolvers; avoid forcing public resolvers if internal name resolution is needed.
When to choose each resolver
- Choose Google Public DNS when minimal latency, broad anycast coverage, and documented large-scale support are priorities.
- Choose UncensoredDNS when the primary concern is privacy from large US-based providers, potential uncensored responses, and preference for a smaller European operator — provided the operator's transparency and uptime meet needs.
FAQ
What are the official IPs and DoH endpoints for Google Public DNS?
Primary IPv4: 8.8.8.8 and 8.8.4.4. DoH endpoint: https://dns.google/dns-query. More details: Google Public DNS docs.
Where to confirm UncensoredDNS current IPs and protocol support?
Always consult the official UncensoredDNS pages: UncensoredDNS. Provider pages list live IPs, DoH/DoT/DNSCrypt endpoints and any changes.
Does UncensoredDNS record queries?
UncensoredDNS advertises a privacy-oriented stance. Evaluate the provider's privacy policy and any available third-party audits. For official statements see UncensoredDNS.
Can DNS requests be legally requested from Google in the UK?
Yes. Google may respond to lawful access requests from UK authorities via legal channels. The scope depends on location of data and applicable treaties. See Google's transparency resources: Google Transparency.
Which resolver supports DNS-over-HTTPS best for browsers?
Both resolvers support encrypted transports in different ways. Google provides stable DoH endpoints that major browsers (Chrome, Firefox) recognize. UncensoredDNS may require manual configuration or a client depending on platform support.
How to verify which resolver is in use?
Use online tests (e.g., Cloudflare help) or the command line: dig +short txt whoami.cloudflare @1.1.1.1 (substitute resolver) or examine OS network settings.
Does DNSSEC protect privacy?
DNSSEC protects integrity and authenticity of DNS responses, not query privacy. Use DoH/DoT/DNSCrypt to encrypt queries; use DNSSEC to validate responses.
Will changing resolvers affect geolocation content?
Yes. Some services use DNS-based geolocation or CDN steering. Switching resolvers can change resolved CDN endpoints and therefore content localization.
How to test latency from home in England?
Run: dig +time=2 @8.8.8.8 example.com and compare to dig +time=2 @91.239.100.100 example.com. Repeat samples at different times of day and average results.
Conclusion
Choosing between UncensoredDNS and Google Public DNS requires weighing privacy posture, jurisdictional risk, performance, and protocol support. Google offers lower median latency and broad anycast availability, while UncensoredDNS emphasizes a privacy-oriented, European-hosted option with alternative encryption support (DNSCrypt, DoH as documented). For England-based users, executing the reproducible tests above and reviewing provider transparency materials is recommended before committing to a resolver for critical privacy needs.
