What Is My DNS Server? How to Check Your DNS Settings
Every time you open a site, a quiet handoff happens in the background: your device asks a name-translation service to turn a name like example.com into the numbers a computer can actually connect to. Most people never think about which service they use — until pages load slowly, a site won’t open, or a privacy tool flags something odd.
This guide explains what a DNS server is, how to find the one your device is using, and how to check it on any operating system. You’ll also learn how to read common records, why some updates take time to show up, and how to keep your requests private.
What Is a DNS Server?
DNS stands for Domain Name System. A DNS server is the part of that system your device talks to when it needs to look up a website. Think of it as the internet’s address book: you know the name of a place, and the server hands back the exact location.
When you type a domain into your browser, your device doesn’t magically know where that site lives. It sends a small request to that server, which replies with the matching IP address. Only then can the page open. Your device usually gets one automatically from your provider, but you can configure it to use a different service whenever you like.
How DNS Works: From Request to Website
The moment you visit a website, your device fires off a DNS query. Here is the short version of what happens next.
First, a recursive resolver — usually run by your internet provider or a public service — receives the request and works out how to resolve it. This recursive DNS resolver acts as the middleman: if it already knows the answer, it replies instantly; if not, it goes looking.
The resolver then works down the chain. It asks a root server, which points it to the servers for the correct top-level domain (the TLD, such as .com or .org). Those TLD servers pass it along to the authoritative name servers for the exact domain name. These nameservers hold the real records and return the server IP address for the hostname you asked about.
Your device and the service parse that reply, and the page loads. All of this — the back-and-forth these systems use to communicate — finishes in a fraction of a second, and those DNS queries repeat for every asset on the page. If you want the bigger picture of how machines find each other, our guide on what a VPN is and how to use one puts it in context.
How to Find Your DNS Server Address
Want to know which DNS server your device is actually using? The steps depend on your platform, but each one takes under a minute.
On Windows
Open Command Prompt and type ipconfig /all, then press Enter. Scroll to your active connection and look for the “DNS Servers” line — that’s the address your Windows PC is requesting right now.
On macOS
Open System Settings → Network, pick your connection, and click Details → DNS. The listed addresses are the ones your Mac uses. You can also run scutil --dns in Terminal for the full configuration.
On Android
To find your DNS server on Android, open Settings → Network & internet → Private DNS. If it shows a provider name, that’s what’s active; if it shows “Automatic,” your phone is using the network’s default. Some phones display the current address under the Wi-Fi network’s advanced details.
On Your Router
Because your home gateway hands DNS to every device on the local network, its admin panel is the one place that affects everyone at once. Log in through your browser, then look under DHCP or WAN settings to see which service the whole private network is pointed at. Not sure of the login address? Our walkthrough on how to find your gateway’s IP address covers it, and if you want to swap providers there, see how to change your DNS.
Using an Online DNS Checker
Reading a settings screen tells you what should be in use. An online tool tells you what your connection is really doing. It sends a request and shows which server answered — handy when you want to verify that a VPN or a new provider took effect.
To test this way, open a DNS lookup tool in your web browser and run a request against a domain. The result confirms the server in play and can reveal DNS leaks, where DNS requests slip outside an encrypted tunnel and expose the sites you look up. our DNS leak test does exactly this in one click, and our what-is-my-IP tool pairs well when you compare results — it even answers the common “check my DNS” question at a glance.
Two quick habits help here. Check the DNS answer for the provider you expect, not your internet provider, and confirm the DNSSEC validation flags where the tool reports them — that signals the answer wasn’t tampered with in transit. If you spot a mismatch, a fix like preventing a WebRTC IP leak is the usual next step.
DNS Propagation: When DNS Changes Take Time
Update a domain’s records and the change doesn’t reach everyone instantly. That delay is called propagation. Resolvers around the world hold the old answer until it’s allowed to expire, so it can take a while for new DNS data to propagate globally.
Two things control the wait. The TTL (time to live) value tells each resolver how long to keep a record in the DNS cache before fetching a fresh copy, and each server’s own cache holds the answer until that clock runs out. Lower the value before a planned move and the reload happens faster afterward.
If you’ve just made an edit and want to watch it spread, run a check DNS propagation test. A global DNS propagation checker queries servers in many regions at once, so a single DNS propagation check shows you where the new value is live and where the old one lingers — often broken down by server location. These global DNS checks are the quickest way to confirm a move finished. To force your own machine to drop stale entries sooner, our note on how to flush old DNS entries walks through it per platform.
Common DNS Record Types
Each record is a single instruction stored for a domain. When a tool returns “records,” these are the types you’ll meet most often:
- A / AAAA — map a name to its numeric address. This is the core translation your device needs.
- CNAME record — points one name at another, so several hosts can share a single target.
- MX record — tells mail servers where to deliver a domain’s email.
- NS record — lists the authoritative servers responsible for the domain.
- PTR record — the reverse lookup, matching an address back to a name.
- SOA — the “start of authority,” holding admin details and the zone’s timing values.
- SRV — points to the server and port for a specific service.
Reading these tells you almost everything about how a zone is set up.
Public DNS Servers and Providers
Your ISP assigns a default one, but you’re free to choose from many DNS providers. These shared servers are open for anyone to use and often bring faster or more consistent results than the ones ISPs hand out. Popular free DNS options include Cloudflare at 1.1.1.1 and Google at 8.8.8.8.
Switching to a different DNS service changes where your requests go and, with it, who can see the domains you request. That’s a real privacy detail worth understanding — the DNS information a service logs can reveal a lot. If you’re weighing the newer addressing standard too, our IPv4 vs IPv6 comparison explains what changes, and changing your IP address without a VPN is a related tweak. Whichever route you pick, remember that even the best public option still hands your requests to a company somewhere.
Take Your DNS Privacy One Step Further with Planet VPN
Checking and switching your provider is a smart start — but on its own it only changes who translates your names.

Planet VPN closes that gap: it encrypts your traffic and routes every request through its own protected servers, so your activity stays with you.
Core protection is free, forever — no credit card, no trial clock. You get encrypted connections across the free locations, with the option to add more locations and speed whenever you want.
Download Planet VPN free and set it up in a couple of clicks on any device. Pair it with a trusted provider, and you cover both halves of the privacy picture.
Frequently Asked Questions (FAQs)
Is 8.8 8.8 the fastest DNS?
8.8.8.8 is Google’s public resolver, and it’s one of the quickest and most reliable options in many regions — but the best pick always depends on where you are and how your network routes traffic. Cloudflare’s service often measures just as well, so the only way to know the right choice for your connection is to test a couple and compare.
Is your DNS your IP address?
No — they’re two different things. Your IP address identifies your device on the internet, while your DNS is the service your device asks to translate website names into addresses. You can change your provider without changing your IP, and vice versa.
What is my DNS server on Android?
Open Settings → Network & internet → Private DNS to see it. If a provider name is listed, that’s what’s active; if it’s set to “Automatic,” your phone uses whatever the current network assigns. For a specific Wi-Fi network, you can also view the address in that network’s advanced settings.
How do I change my DNS server?
On most devices you edit the network’s DNS field and enter a new address — for example a public option like 8.8.8.8. The exact path differs per platform, so our step-by-step guide on how to change your DNS covers Windows, Mac, Android, and the network’s admin panel in detail.
Is changing DNS to 8.8.8.8 safe?
Yes. 8.8.8.8 belongs to Google’s well-maintained public service, used by millions of people. Pointing your device to it doesn’t add extra risk. Keep in mind that whichever provider you choose can see the domains you look up, which is why pairing a public option with encryption matters if privacy is your goal.
How can I find my DNS server address?
Use your device’s network details or an online tool. On Windows, run ipconfig /all; on a Mac, open Network → DNS; on Android, check Private DNS. For an outside view of what your connection is really using, run an online DNS leak test, which reports the server answering your requests.
