What is DNS and why you should check it

DNS, or Domain Name System, is basically the phonebook of the internet. It translates friendly names like example.com into IP addresses that computers use to talk to each other. If your DNS server is slow, blocked, or unreliable, your browsing might feel sluggish, or you could be directed to inaccurate results. Some people also want DNS privacy protections like DoH or DoT to reduce the chance that their DNS queries get snooped on a network you’re using.

In this chapter, you’ll learn three simple steps to identify the DNS server your device is actually using, verify it with quick checks, and learn options to switch to a provider that fits your needs—without getting overwhelmed.

Step 1: Find the DNS settings on your device

The first step is to identify what DNS servers your device is configured to use. It’s normal for a device to have multiple DNS servers listed, with one actively used depending on the network path.

Windows

• Open Command Prompt type cmd in the Start menu and press Enter.
• Run: ipconfig /all
• Look for the “DNS Servers” line under your active network adapter. The addresses listed are your DNS servers. If you see more than one, Windows will try them in order.

Tip: You can also run nslookup to see which DNS server responds when you query a domain:

• Run: nslookup example.com
• In the output, you’ll see a line that starts with “Server:” and another line with “Address:”. The Address shows the DNS server that answered.

macOS

• Open System Preferences > Network.
• Choose your active network Wi‑Fi or Ethernet and click Advanced.
• Go to the DNS tab. You’ll see a list of DNS servers your Mac is configured to use.

• Open Terminal and run: scutil –dns | grep -i ‘nameserver’
• You’ll see lines like “nameserver : 8.8.8.8” showing the listed DNS servers.

Linux

• Different desktop environments show this a bit differently, but common paths include:
  • Check resolv.conf: cat /etc/resolv.conf
  • For systems using systemd-resolved: systemd-resolve –status
• For NetworkManager users: nmcli device show | grep IP4.DNS
• The DNS server addresses you see are the ones your system will try first.

iOS iPhone/iPad

• Open Settings > Wi‑Fi.
• Tap the “i” next to your connected network.
• Scroll to DNS and you’ll see the DNS servers listed there. If you’re using a VPN or DoH, these settings can differ, so check in the VPN app or DoH configuration as well.

Android

• Open Settings > Network & internet > Wi‑Fi.

• Tap your connected network, then Advanced or DNS. You’ll see the DNS addresses listed.

• Some devices route DNS through a VPN or DoH app, so you may also check in those apps for a fallback or override.

• Quick tip for all devices: if you don’t see DNS servers listed explicitly, your device might be using DHCP-provided settings or a VPN/DoH configuration. In that case, moving to a known DNS provider like Google 8.8.8.8, Cloudflare 1.1.1.1, or Quad9 9.9.9.9 usually requires explicit changes in the network settings or in the VPN/DoH configuration.

Step 2: Confirm the active DNS server for your current connection

Knowing the configured DNS servers is one thing. knowing which one actually answered your most recent DNS query is another. This helps you confirm the path your traffic is taking. Clear remote desktop issues on server with these expert tips and RDP troubleshooting best practices

• Open Command Prompt and run: nslookup

• Then type a domain you want to check, for example: example.com

• The output shows the server that answered, with lines like:
  Server: dns-server-name
  Address: x.x.x.x

• If you want to force a query to a specific server, you can run: nslookup example.com 8.8.8.8

• This will return the response from Google’s DNS server or whichever IP you specify. Get Your Dns Server Working In 3 Simple Steps Troubleshooting Guide

• Open Terminal and run: dig +short example.com

• You’ll get the IP addresses as responses, but to see which server is used by your machine, you can run:
  dig @ example.com

• If you want to check the default resolver, you can query:
  dscacheutil -q host -a name example.com
  or
  scutil –dns | grep -i ‘nameserver’

• Use dig or nslookup similarly:
  dig +short example.com
  nslookup example.com

• To see which DNS server responded:
  dig +trace example.com
  The first server in the trace is the root server, and the chain shows the path. the last hop is your final resolver. How to insert gridview data in sql server

iOS and Android DoH/VPN scenarios

• If you’re using DNS over HTTPS DoH through a browser or app, your DNS requests might be encrypted and not visible through typical OS-level DNS viewer.
• In this case, open the DoH or VPN app settings to see which resolver is configured for example, Cloudflare, Google, or your enterprise resolver.

Quick tests you can run anywhere

• Query a domain you know has multiple DNS records e.g., example.com and compare results from different DNS servers you’ve tested.
• Use an online DNS checker see Resources section below to verify that your DNS server appears as your current resolver from outside your device.

Step 3: Verify with an online check and consider privacy

After you’ve confirmed the DNS settings, it helps to verify that your browser traffic is using the DNS resolver you expect and that there are no leaks leaking to another provider. This is especially important if you’ve enabled DoH/DoT or switched to a privacy-focused provider.

• Do a quick DNS leak check: Visit dnsleaktest.com Extended Test or ipleak.net and run the test. You’ll want to see your chosen DNS servers listed rather than a random ISP server. If you see a different server, you might be using a VPN, DoH, or a misconfigured network path.
• Verify encryption for DNS queries: If privacy matters, enable DNS over HTTPS DoH or DNS over TLS DoT where supported. This ensures your DNS queries aren’t easily observed on the network.
• Consider testing latency and reliability: You can compare response times from different DNS servers. For example, Google DNS 8.8.8.8, Cloudflare DNS 1.1.1.1, and Quad9 9.9.9.9 each have their own performance profiles depending on your location and network path.
• Check for DNSSEC support: Some DNS providers offer DNSSEC validation, which helps verify the authenticity of DNS responses and prevent certain types of spoofing.

Optional: DNS providers and DoH/DoT encouragement

• Google Public DNS: fast, reliable, broad coverage. supports DoH.
• Cloudflare 1.1.1.1: privacy-focused, strong DoH/DoT support, fast in many regions.
• Quad9 9.9.9.9: security-focused, blocks access to known malicious domains, supports DoH/DoT.
• For enterprise or advanced users, DoH and DoT can be configured at router level or VPN level for consistent protection across devices.

Quick tips and best practices

• If you’re experiencing slow browsing, switching to a different primary DNS server can dramatically improve response times. Try Cloudflare 1.1.1.1 or Google 8.8.8.8 as a starting point and see if there’s improvement.
• If you’re concerned about privacy, enable DoH or DoT where possible. Some devices require a browser extension or a specific app to route DNS queries over HTTPS.
• Use a consistent DNS setup across devices in a household or office for uniform security and troubleshooting simplicity.
• For travelers or mixed networks home, coffee shops, airports, consider a DoH-capable app or VPN that automatically uses encrypted DNS, rather than manually reconfiguring every device.
• Keep your firmware and OS up to date. DNS-related features and DoH/DoT implementations improve with updates.

Frequently asked topics and scenarios

• Do I need to change my DNS to be faster? Not always, but many people see noticeable improvements with public DNS providers that have optimized networks and global nodes. If you’re often around the world or on slow networks, testing a few options can be worth it.
• How can I know if my ISP’s DNS is slow or unreliable? Run a quick test by setting a different DNS like 1.1.1.1 or 8.8.8.8 for a day or two and compare page load times and responsiveness.
• Will changing DNS affect content filtering or parental controls? It can, depending on how those controls are implemented. Some parental controls operate at the DNS level. changing providers may bypass or require reconfiguration of those controls.
• Is DNS over HTTPS required to protect privacy? It’s a strong privacy feature, but not a silver bullet. DoH encrypts DNS queries between you and the DoH resolver, but the resolver itself might still log data. Combine with a privacy-conscious provider and good network practices.
• Can I use multiple DNS servers? Yes. Most devices support a primary DNS and a secondary fallback DNS. If the primary fails, the system will try the secondary automatically.
• How do I revert changes if something goes wrong? Keep a note of the original DNS addresses. Reapply them or use system restore points where available if you’re on a desktop OS.
