01.Introduction: What Does DNS Actually Do?
DNS is effectively the internet's phonebook. It translates human-friendly addresses like "valorant.com" into machine-readable IPs like "104.16.1.1." A slow DNS server takes longer to find the destination, while a fast DNS provides an instantaneous connection.

02.Chapter 1: Running the DNS Jumper Benchmark
Finding the Fastest Provider
1. Download DNS Jumper (Portable version, no installation required).
2. Open the utility and select "Fastest DNS" from the sidebar.
3. Click "Start DNS Test."
The tool will ping dozens of global servers to find which one offers the lowest latency (ms) for YOUR exact location.
Typically, Cloudflare or Google will win, but occasionally a local ISP's internal DNS may prove superior.
03.Chapter 2: Implementing Changes in Windows
Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings.
Right-click your active connection (Ethernet/Wi-Fi) > Properties.
Select Internet Protocol Version 4 (TCP/IPv4) > Properties.
Select "Use the following DNS server addresses" and input the winning results from your benchmark.
04.Chapter 3: IPv6 DNS Configuration (Critical for Stability)
Many users ignore the IPv6 protocol. If your ISP utilizes IPv6, your gaming traffic may prioritize it over IPv4.
Configure Internet Protocol Version 6 (TCP/IPv6) as well:
- Cloudflare IPv6: 2606:4700:4700::1111
- Google IPv6: 2001:4860:4860::8888
A1.Chapter 4: Flushing the DNS Cache
After switching providers, you must clear the old entry cache to ensure the new settings take priority.
Open the Command Prompt (CMD) as Administrator.
Type: ipconfig /flushdns and hit Enter.
You should receive a success message: "Successfully flushed the DNS Resolver Cache."
A2.Chapter 5: Does DNS Improve In-Game Ping?
The Myth: DNS directly lowers your ping during a match.
The Reality: DNS only functions during the initial CONNECTION (Login, Matchmaking). Once the game establishes a connection to the server's IP, the DNS service is no longer active.
However, a poor DNS may fail to resolve the nearest server correctly, routing you to a distant region with high ping. In this specific scenario, a fast DNS helps indirectly.
A3.Chapter 6: DNS Over HTTPS (DoH)
Modern browsers (Chrome/Edge) often use encrypted DNS.
While excellent for privacy, this adds a few milliseconds of decryption overhead. For competitive gaming, the traditional UDP DNS (Port 53) remains the gold standard for raw speed.
A4.Chapter 7: DNS-Based Ad Filtering
Providers like AdGuard DNS filter ads at the network level.
This can save bandwidth, but use it with caution: some free-to-play titles may fail to load reward videos or in-game stores if their domains are blocked by the filter.
Chapter 8: Router-Level Configuration
The most efficient method is configuring your DNS directly on your Home Router.
This ensures your PC, consoles, and mobile devices automatically benefit from the faster resolver without manual per-device setup.
Chapter 9: Avoiding Default ISP DNS
ISP-provided DNS servers are often unreliable, slow to update entries, and can be subject to regional censorship. Furthermore, many ISPs track and sell browsing history; third-party providers like Cloudflare offer significantly better privacy.
Chapter 10: ExitLag and DNS Interaction
Software like ExitLag or NoPing bypasses your Windows DNS settings entirely, utilizing their own resolution systems to find the most direct routing for your specific game's traffic.
