In this comprehensive step-by-step guide, we’ll explain what the Chrome DNS cache is, why it matters, how to clear it safely on Android devices, and the potential benefits and risks of doing so. Whether you’re a regular Android user or a tech enthusiast who loves optimizing performance, this article will help you understand everything about chrome //net-internals/#dns clear host cache android in simple, practical terms.
What Is DNS and Why Does It Matter in Chrome?
Before diving into the steps, it’s essential to understand what DNS is and how it affects your browsing experience.
What Is DNS?
DNS stands for Domain Name System — it acts as the phonebook of the internet. When you type a website like www.google.com your browser doesn’t understand names; it understands IP addresses (like 142.250.182.206).
The DNS converts that domain name into the corresponding IP address, helping your device find and connect to the right web server quickly.
How DNS Works in Simple Steps
| Step | Process | Example |
|---|---|---|
| 1 | You type a website name in Chrome. | www.youtube.com |
| 2 | Chrome checks its DNS cache to see if it already knows the IP. | If cached, it connects instantly. |
| 3 | If not cached, Chrome asks a DNS server to resolve it. | DNS server provides IP: 142.250.190.78. |
| 4 | The IP is stored (cached) for faster access next time. | DNS cache speeds up browsing. |
Understanding Chrome’s DNS Cache
Every browser, including Google Chrome, keeps a local DNS cache — a small temporary storage of IP addresses for the websites you visit.
When the cache is fresh, Chrome can load websites faster. However, when the cache becomes stale, corrupted, or outdated, it can lead to browsing issues such as:
- Websites not loading properly
- Wrong website IP resolution
- “This site can’t be reached” errors
- DNS probe errors (e.g.,
DNS_PROBE_FINISHED_NXDOMAIN)
That’s when clearing the cache via chrome //net-internals/#dns clear host cache android becomes useful.
What Is chrome //net-internals/#dns?
The URL chrome://net-internals/#dns is an internal Chrome tool used primarily for network debugging and analysis.
When accessed, it provides several advanced network functions, including:
- Viewing DNS host cache entries
- Clearing host cache
- Tracking network requests
- Testing connection behaviors
It’s part of Chrome’s Net Internals page — a developer-focused feature that helps diagnose network-related issues.
💡 Note: Although this tool is mostly used by developers, regular users can also safely use it to ṭ or to clear outdated DNS cache data.
Why You May Need to Clear DNS Cache on Android
You might wonder — why bother clearing the DNS cache?
Here are the most common reasons Android users need to use chrome //net-internals/#dns clear host cache android:
| Reason | Explanation |
|---|---|
| 1. Website not loading properly | Sometimes a site changes its IP address, but Chrome keeps using the old one from cache. |
| 2. Website moved to a new server | Clearing the cache forces Chrome to fetch the new IP from the DNS server. |
| 3. “DNS Probe” or network errors | Issues like DNS_PROBE_FINISHED_BAD_CONFIG can be resolved by clearing the cache. |
| 4. Privacy & security | DNS cache can temporarily store visited sites; clearing it removes that trace. |
| 5. Speed optimization | A clean DNS cache helps Chrome rebuild it efficiently, improving load times. |
In short, clearing your DNS host cache ensures Chrome always uses updated, accurate, and secure DNS information.
Step-by-Step Guide: How to Use chrome //net-internals/#dns Clear Host Cache Android
Now let’s get practical. Here’s the detailed step-by-step process to clear your Chrome DNS cache on Android.
Step 1: Open Google Chrome on Your Android Device
Launch your Chrome browser (make sure it’s updated to the latest version for best performance).
Step 2: Enter the Internal URL
In the address bar, type the following and hit Enter:
chrome://net-internals/#dns
If Chrome doesn’t accept it directly, you can type:

✅ Restart your phone periodically — helps refresh system-level DNS and sockets.
These small habits ensure smoother connectivity and fewer DNS-related issues in the long run.
Advanced Insight: How Chrome Handles DNS Internally
For advanced users, Chrome maintains DNS cache entries with time-to-live (TTL) values. Once TTL expires, entries are refreshed automatically.
However, if a DNS record changes before TTL expiration, Chrome may still use the old entry — causing connection issues.
That’s why chrome //net-internals/#dns clear host cache android acts as a manual override, forcing Chrome to drop all old entries regardless of TTL timing.
Internally, this command clears data from:
HostCache: DNS resolution table.DnsSession: Active DNS transactions.Socket Pools: Persistent TCP connections associated with cached domains.
This deeper level of clearing ensures no outdated IP references remain.
The Role of DNS over HTTPS (DoH) in Chrome
Chrome now supports DNS over HTTPS (DoH) — a feature that encrypts DNS queries for better privacy.
If you have DoH enabled, clearing the DNS cache using chrome //net-internals/#dns clear host cache android still works, but Chrome rebuilds it through encrypted channels.
To enable DoH:
- Go to Chrome Settings → Privacy and Security.
- Tap “Use secure DNS.”
- Choose a provider (Google DNS, Cloudflare, or custom).
With DoH, your DNS lookups become both private and faster, enhancing overall browsing security.
