A custom DNS server almost never lowers your in-game ping, and a VPN usually raises it, because ping is set by the network path between your PC and the game server, not by name lookups. A VPN can help only in specific cases, such as a poorly routed internet provider path, and DNS matters mostly for how quickly a game finds its servers when you first connect.
That answer surprises many players, since both tools are often advertised as ping fixes. This guide explains what each one changes, what actually controls latency, and how to measure the result on your own connection so you can decide with evidence. Results depend on your internet provider, your region and the game, so treat the explanations as general principles and check your provider and game documentation for specifics.
What Ping Really Measures
Ping is the round-trip time for a small message to travel from your PC to the game server and back. It is affected by physical distance, the number of network hops, the quality of each link, congestion along the route, and the load on your own home network. Packet loss and jitter, which is variation in delay, also affect how a game feels even when the average ping looks acceptable.
Once your game has connected to a server, each packet travels by IP address. The game does not look up a name for every packet, so the speed of your DNS server has no ongoing effect on the delay of those packets. That is the core reason DNS changes rarely change in-match ping.
What a Custom DNS Does
Where DNS Helps
DNS translates names such as a game’s login or matchmaking address into IP addresses. A slow or unreliable resolver can make logins, store pages, patch downloads and server lists take longer to start. Changing resolvers may speed up those moments, and a better resolver can reduce failed lookups.
Where DNS Does Not Help
After the connection is made, DNS is out of the picture. A different resolver does not shorten the route to the server, reduce packet loss or fix Wi-Fi interference. Some resolvers can occasionally return a different server address for services that use location-based answers, which may change which data center you reach, but that is not a guaranteed improvement and can be worse.
What a VPN Does
Why a VPN Usually Adds Ping
A VPN encrypts your traffic and sends it to a VPN server before it reaches the game. That adds at least one extra hop and extra processing, so the ping is typically higher than a direct connection unless the VPN path is better than the default one.
When a VPN Can Help
Sometimes an internet provider routes traffic to certain servers through a congested or indirect path. A VPN with a better route might bypass that path and lower ping or reduce packet loss. Specialized gaming routing services work on this idea. The benefit is situational and varies by game and provider, so the only reliable way to know is to measure.
Other Reasons People Use a VPN
A VPN can protect you from some forms of attack on your home address, such as denial-of-service attempts, and can protect traffic on public networks. It is also used to access different regions, but be careful: some games and platforms restrict or prohibit this in their terms, and bypassing region limits can risk account problems. Read the game’s rules before you try.
Comparison at a Glance
| Factor | Custom DNS | VPN |
|---|---|---|
| Effect on in-match ping | None in most cases | Usually higher, occasionally lower |
| Effect on login and server lookup | Can be faster | May be slower or faster |
| Packet loss | No direct effect | May improve if routing is poor |
| Privacy and security | Some resolvers offer filtering | Encrypts traffic to the VPN server |
| Risks | Low | Terms of service issues, added latency |
The table shows that neither tool replaces the basics. If your ping is high, the cause is more likely your connection type, router or distance to the server.
What Actually Lowers Ping
- Use a wired Ethernet connection instead of Wi-Fi. This removes wireless interference and reduces jitter.
- Select the nearest game server region available to you.
- Pause large downloads, cloud backups and video streams on the network while you play.
- Check router settings for features that reduce delay under load, often called smart queue management or quality of service, if your router supports them.
- Restart your modem and router to clear temporary issues, and update the router firmware.
- Contact your internet provider if ping spikes or packet loss are present at certain times of day.
Safety note: change router settings carefully and write down the original values, so you can restore them if something stops working. Do not install unknown tools that claim to cut ping, as some are bundled with unwanted software.
Choosing a DNS Provider or VPN Sensibly
If you decide to change DNS anyway, the safest approach is to pick a well-known public resolver, enter its addresses in your router so every device benefits, and keep a note of your previous settings. Many players also try the resolver their internet provider supplies first, because it is often physically close and fast enough. Some resolvers add filtering for malware or adult content, which is a privacy and safety choice more than a speed choice.
Questions to Ask About a VPN
Look for a provider with servers near the game server region, a clear privacy policy, and support for the protocols your device handles well. A VPN that uses a modern, lightweight protocol typically adds less delay than an older one. Free services are often limited in speed and may collect or sell data, so read the policy before you trust one with all your traffic.
Questions to Ask About Gaming Routing Services
Some paid services market themselves as gaming route optimizers. They work by sending only the game traffic through a managed path. Whether one helps depends on your provider and the game, so look for a trial or refund window and compare results using the measurement method below. Be skeptical of any service that guarantees a fixed ping reduction.
Other Causes of Lag That Neither Tool Fixes
Wi-Fi Interference and Distance
Wireless links share airtime with neighbors and household devices, and distance or walls increase retransmissions. The result is jitter, which feels like rubber-banding even when the average ping is low. A cable removes the problem, and a mesh system or a closer access point can reduce it if you must stay wireless.
Bufferbloat
When someone on your network uploads or downloads at full speed, your router’s queues can fill, and game packets wait behind them. Routers with queue management features reduce this effect, which you can recognize as ping that spikes only when other devices are busy.
Server Load and Tick Rate
Sometimes the game server itself is the bottleneck. A busy server or a low update rate can feel laggy no matter how clean your connection is. If many players report the same problem at once, the cause is probably not your setup.
How to Measure Before You Decide
Step 1: Record a Baseline
Play a few matches on your normal connection and note the in-game ping and packet loss display if the game has one. Do this at the time of day when you normally play.
Step 2: Change One Thing at a Time
Switch DNS or connect through a VPN, then repeat the same matches. Changing both at once makes the results impossible to interpret.
Step 3: Compare Averages and Stability
Look at both the average and the spikes. A slightly higher ping that is perfectly steady can feel better than a lower average with sudden jumps.
Before You Try Either Checklist
- Confirm you are on a wired connection if possible.
- Check the game’s rules on VPN use.
- Record your baseline ping and packet loss.
- Use reputable DNS providers and VPN services with clear policies.
Common Mistakes
- Expecting a DNS change to reduce ping inside a match.
- Using a free VPN with limited bandwidth and unclear privacy practices.
- Choosing a VPN server far from the game server.
- Changing several network settings at once and not knowing which helped.
- Ignoring Wi-Fi problems while looking for a software fix.

Frequently Asked Questions
Will changing my DNS lower my ping?
Almost always not during a match. It may help logins and server lookups start faster, but it does not change the route taken by game traffic.
Can a VPN reduce lag?
Occasionally, if your provider routes traffic badly and the VPN uses a cleaner path. In most cases it adds a little delay, so measure before relying on it.
Is it safe to use a VPN with online games?
It is generally possible, but some games and anti-cheat systems have rules about it. Check the terms of the game and your VPN service.
What is the best first step for high ping?
Use a wired connection and check which server region you are connecting to. These two changes address the most common causes.
