Change your DNS without root for faster internet, lower ping in games and safer browsing.
DNS Changer by Protectstar™ is a lightweight Android app that lets you switch DNS servers on your phone or tablet in just a few taps. Use fast, privacy‑friendly DNS on Wi‑Fi and mobile data, improve loading times, help reduce ping and lag in many online games and use DNS services that can filter many advertising, tracking and malicious domains at DNS level – all without root access or complicated network settings.

Why change your DNS server?
• Your provider's default DNS can be slow or overloaded, so websites, apps and games open more slowly than they should.
• Some websites and services are blocked or filtered at DNS level and cannot be reached with standard settings.
• A faster DNS server reduces DNS lookup time and makes everyday browsing, search and streaming feel more responsive.
• Security‑focused DNS providers can block known phishing, malware and other unsafe domains before the page loads.
• A better DNS route can help lower latency and ping in many online and mobile games and make connections more stable.

Made for everyday use and gaming
• Speed up browsing, social media, streaming and cloud services on slow or unstable networks.
• Help reduce ping and packet loss in many online games with gaming‑oriented DNS profiles.
• Switch DNS profiles in seconds when you move between home Wi‑Fi, mobile data, work mode and gaming mode.
• Works on most Android phones and tablets without root or router changes.

Key features
• Change DNS for Wi‑Fi and mobile data (3G/4G/5G) without root.
• Supports IPv4 and IPv6 DNS servers.
• Ready‑made profiles: Security DNS, Privacy DNS, DNS that can filter many ad and tracking domains, Gaming DNS and Family‑filter DNS.
• Choose from popular public DNS providers such as Cloudflare, Google Public DNS, AdGuard DNS, Quad9 and CleanBrowsing, or add your own custom IPv4/IPv6 servers.
• Built‑in DNS speed test (PRO) to automatically find a fast DNS server for your network and location.
• Optional DNS request logging and monitoring (PRO) so you can see which domains your apps connect to and spot unusual activity.
• Save DNS profiles like “Home”, “Work”, “Gaming” or “Kids” and switch between them in seconds (PRO).

Privacy and security
• Use privacy‑friendly DNS providers to reduce tracking and some types of traffic analysis by third parties.
• DNS‑level filtering can block access to many malicious, phishing or suspicious domains before they reach your browser or apps – especially useful on public Wi‑Fi networks.

Family‑safe DNS and parental control
• Family‑oriented DNS profiles can help block adult websites, gambling pages and other categories that are not suitable for children.
• Filtering happens at DNS level, so protection applies to the whole device – all apps and browsers – with one central setting.

PRO features and technical details
• Per‑app control: choose which apps should use DNS Changer and which should keep the system default DNS (PRO).
• Advanced DNS logs and a WHOIS tool with map view help you analyse traffic and detect suspicious or unwanted domains (PRO).
• Create custom DNS profiles for gaming, work, streaming or family and switch quickly between them as needed (PRO).
• DNS Changer uses Android's VpnService API to create a local VPN interface and change only the DNS server address used by your device. It is not a full VPN service: your traffic is not tunnelled through remote VPN servers and your public IP address does not change. The app does not store your browsing history or sell your data; PRO features are offered as an optional in‑app subscription so you can have more control over DNS settings while keeping your connection fast and stable.
