DNS Changer: Net Optimizer

Net Optimizer finds and connects to the fastest DNS server for your network in one tap. Faster web browsing, lower ping in online games, and a snappier connection — without changing your data plan or rooting your device.

 

★ ONE-TAP DNS OPTIMIZATION

Tap once. We scan top public DNS resolvers in real time, rank them by live latency on your current Wi-Fi or mobile data, and switch you to the winner automatically.

 

★ REAL SPEED TEST, NOT GUESSWORK

Every provider is probed with proper RFC 8484 DNS-over-HTTPS queries. The result is your actual measured latency, not a marketing number.

 

★ WORKS ON WI-FI & MOBILE DATA

Detects network changes automatically. Re-scans and re-connects when you switch between Wi-Fi and mobile data (3G / 4G / 5G).

 

★ 18+ TRUSTED DNS PROVIDERS

Cloudflare (1.1.1.1), Google (8.8.8.8), Quad9, OpenDNS, AdGuard, NextDNS, Mullvad, Control D, CleanBrowsing, Cloudflare for Families, OpenDNS FamilyShield, DNS.WATCH, Verisign, Yandex DNS, Comodo Secure DNS, Alternate DNS, UncensoredDNS, OpenNIC.

 

★ FILTERS THAT MATCH YOU

• Fastest 5 — speed-only ranking

• No-logs — privacy-focused providers

• Family — adult-content blocking

• Ad-block — ad and tracker filtering

 

★ HOW IT WORKS

Your default DNS resolver controls how fast every domain on the internet maps to an IP address. ISPs often run slow or congested resolvers, which adds noticeable delay to every web request and online-game connection. Net Optimizer measures public DNS providers from your device, then switches your phone to the fastest one. Browsing feels snappier and games see lower ping.

 

★ NO ROOT REQUIRED

Uses Android's VpnService to safely route DNS queries — no root, no third-party VPN server. Your IP and browsing stay private to your normal network.

 

★ FULLY PRIVATE

• No account required

• No tracking

• No backend server — every probe is direct from your device to each public DNS provider

• Open about its limits: DNS optimization improves response time, not download or upload speed

PERMISSIONS

• VpnService — used only to redirect DNS queries to the resolver you choose. No traffic is sent to a remote VPN server.

• Network state — to detect Wi-Fi vs mobile data and trigger re-scans on change.

• Notifications — to surface the active DNS in the notification shade.

• Display over other apps (optional) — for the Auto-Optimize popup when the network changes.

 

NOT A MAGIC BULLET

DNS settings do not change your download or upload speed. They change the time before a request even starts. On slow or congested ISPs the improvement is dramatic; on already-fast networks it's modest.
