What is DNS and why it matters Creating a second dns server everything you need to know
- DNS stands for Domain Name System. It’s like the phonebook of the internet, translating human-friendly domain names example.com into machine-friendly IP addresses 1.2.3.4 so your browser can load the right server.
- The primary DNS server address you see on your device is the first place your computer asks to translate a domain name. If that server is slow, unreliable, or blocks certain sites, your browsing experience can feel laggy or fail altogether.
- Public DNS providers often offer faster lookups, improved privacy, and extra features like DNS over HTTPS DoH or DNS over TLS DoT. If you’re curious about performance or privacy, it’s worth knowing what DNS you’re using and what alternatives exist.
Where to find your primary DNS server address on each platform
Windows
- Quick check via Command Prompt:
- Open Command Prompt cmd.exe.
- Type: ipconfig /all
- Look for the “DNS Servers” line under your active network adapter. The first IP listed there is your primary DNS server.
- Quick check via Network Settings:
- Go to Settings > Network & Internet > Wi‑Fi or Ethernet > your network > Properties.
- Scroll to IP settings and select Edit or IPv4 properties. If you’re using a manual DNS configuration, you’ll see the DNS server addresses listed there.
- Pro tips:
- For a quick, ongoing check, you can run: nslookup example.com
- If you’re using VPN or a corporate network, the DNS you see might be the VPN’s DNS, not your local router’s.
Mac macOS
- System Settings approach macOS Ventura and later:
- Open System Settings > Network > select your active connection Wi‑Fi or Ethernet > Advanced > DNS tab.
- The DNS Servers list shows the primary DNS as the first address.
- Older macOS Menu bar method:
- Hold the Option key and click the Wi‑Fi icon, then choose “Open Network Preferences.” From there, click Advanced and go to DNS.
- Quick verify:
- Open Terminal and type: dig +short example.com
- The response comes from the DNS server you’re using.
Linux
- Common approach using resolv.conf:
- Open a terminal and view the file: cat /etc/resolv.conf
- The lines starting with “nameserver” show the DNS addresses. The first one is typically your primary DNS.
- Systemd-resolved users:
- If your distro uses systemd-resolved, run: systemd-resolve –status
- Look for “Current DNS Server” under your active interface.
- NetworkManager users:
- You can also check via GUI: Network settings > your connection > IPv4 or IPv6 > DNS; the first address listed is your primary DNS.
IOS iPhone and iPad Create a new login in sql server step by step guide
- Steps:
- Open Settings > Wi‑Fi.
- Tap the information button i next to your connected network.
- Scroll to DNS and tap Configure DNS. If it’s set to Automatic, your device uses the DNS provided by the router or network.
- If you’ve set it to Manual, you’ll see the DNS servers listed there, with the first one as the primary DNS.
- Quick check:
- You can also run a quick network test using a third-party app, but the built-in settings give you the authoritative answer.
Android
- Steps devices may vary slightly by vendor:
- Open Settings > Network & Internet > Wi‑Fi > your connected network gear icon.
- Tap Advanced or DNS and you’ll see the DNS 1 and DNS 2 fields. The first value is your primary DNS.
- If your device is set to DHCP, sometimes you’ll only see the DNS values after switching to Static IP settings temporarily to view the fields.
- Quick tip:
- Some Android versions show the DNS values under your Wi‑Fi details directly without making changes.
Testing your DNS to confirm it’s working
- nslookup or dig:
- Windows: nslookup example.com
- macOS/Linux: dig +short example.com
- If you get an IP address back, DNS resolution is working. If you get an error, try again with a different domain e.g., google.com or check your network connection.
- Ping test:
- ping example.com not always reliable for DNS health, but can confirm name resolution is happening
- Traceroute:
- Windows: tracert example.com
- macOS/Linux: traceroute example.com or tracert on Windows
- This helps you see where DNS resolution or routing might be failing.
How to change your DNS safely and effectively
Why switch DNS?
- Speed: Some public DNS providers offer lower latency than typical ISP DNS.
- Privacy: Some providers have stricter privacy policies and don’t log as much data.
- Reliability: Redundant networks can improve uptime if your ISP’s DNS has outages.
- Filtering and parental controls: Some services offer built-in controls.
Steps to switch general approach Create Calculated Columns in SQL Server Like a Pro: 7 Techniques You Need to Know
- Windows:
- Settings > Network & Internet > Ethernet/Wi‑Fi > Properties > IPv4 > Use the following DNS server addresses.
- Enter a primary DNS and an alternate DNS e.g., 1.1.1.1 and 1.0.0.1 for Cloudflare; 8.8.8.8 and 8.8.4.4 for Google.
- Save changes and flush DNS cache: ipconfig /flushdns
- macOS:
- System Settings > Network > select connection > Advanced > DNS > Add + the new DNS addresses.
- Remove or reorder old addresses to set the new primary and secondary servers.
- Flush DNS cache: sudo killall -HUP mDNSResponder
- Linux:
- Edit /etc/resolv.conf or use NetworkManager/systemd-resolved depending on your distro.
- Add or replace with: nameserver 1.1.1.1; nameserver 1.0.0.1
- Restart networking or flush caches if applicable e.g., sudo systemd-resolve –flush-caches.
- iOS:
- Settings > Wi‑Fi > i next to your network > Configure DNS > Manual.
- Add DNS servers, set primary and secondary, then save. If you switch back to Automatic, the device will revert to the network’s DNS.
- Android:
- Settings > Network & Internet > Wi‑Fi > your network > Advanced > DNS 1 and DNS 2.
- Enter the new primary and secondary DNS, then reconnect to the network.
- Quick note:
- Some corporate or school networks push their own DNS settings via DHCP or a VPN. If you’re on such a network, you may need to adjust this through the VPN app or consult your IT administrator.
Tips for choosing a DNS provider
- Speed and latency: Public resolvers like Google Public DNS, Cloudflare 1.1.1.1, and Quad9 have global networks designed for fast responses.
- Privacy: Look for providers that publish their logging policies and offer minimal data retention. Cloudflare emphasizes privacy protections; others may have different policies.
- Security features: DoH DNS over HTTPS or DoT DNS over TLS can help protect your DNS queries from eavesdropping.
- Reliability and uptime: Reputable providers invest in redundant infrastructure and monitoring to minimize outages.
Common issues and quick troubleshooting
- DNS server not responding
- Check the network status, try a different DNS provider, and ensure you didn’t mistype the DNS address.
- DNS server not found for a domain that should exist
- Verify network connectivity, check for DNS leaks, and test with a known good domain e.g., google.com.
- Slow DNS responses
- Run a latency test, compare multiple providers, and consider moving to a provider known for lower latency in your region.
- Problems after changing DNS
- Flush DNS cache, restart devices, and ensure there are no conflicting DNS entries on the router or VPN.
- Router DNS vs. device DNS
- Some devices use router DNS by default. If you want to override, configure DNS settings directly on the device or set a static DNS in the router.
DNS caching explained
- DNS caching stores recent lookups to speed up repeated requests. This means changes you make may not take effect immediately.
- Flushing DNS caches on your devices and router ensures new DNS settings take effect quickly.
- Typical commands where applicable:
- Windows: ipconfig /flushdns
- macOS: sudo killall -HUP mDNSResponder
- Linux: sudo systemd-resolve –flush-caches or sudo /etc/init.d/nscd restart depending on distro
Security and privacy considerations
- DoH and DoT can help keep your DNS queries private from networks you’re connected to, but be aware that the DNS provider will see your queries.
- If you’re concerned about surveillance, read the privacy policy of your chosen DNS provider and consider using a DNS that supports DoH/DoT with minimal data retention.
- Be cautious with free public DNS services that may have aggressive logging or data sharing policies. Always review the provider’s transparency reports or privacy pages.

Frequently Asked Questions
How do I know if my DNS change is working after I switch providers?
After you change DNS, test by loading a site you know the previous DNS struggled with, run nslookup or dig for a domain, and compare response times. If you see fast resolutions and the site loads normally, you’re likely good to go.
Can I use a different DNS for streaming devices like smart TVs?
Yes. Many devices allow you to set DNS per network or per device. Check the device’s network settings to specify the DNS servers you want to use.
Is it safe to use public DNS services?
Public DNS services can be safe and beneficial for privacy and performance, but you should review their privacy policies and features. Prefer providers that support DoH/DoT and publish clear data-retention policies.

What is DNS over HTTPS DoH and why should I care?
DoH encrypts DNS queries, preventing eavesdroppers on the network from seeing which domains you’re visiting. It improves privacy but can be abused if implemented by software that bypasses system-level protections. Consider your threat model when enabling DoH.
What’s the difference between primary DNS and secondary DNS?
The primary DNS is the first server your device queries for resolution. The secondary DNS is a backup if the primary cannot answer. It’s good practice to provide both.
How often should I flush my DNS cache?
You don’t need to flush it routinely. Do so after DNS changes, when you suspect stale records are causing issues, or if you’re troubleshooting DNS resolution.
How can I test DNS performance across providers?
Use tools like DNSPerf or run real-world tests by measuring page load times and time-to-first-byte before and after switching. In some regions, latency to public DNS resolvers may differ significantly.
What should I do if a site loads over HTTPS but not via DNS resolution?
This points to a DNS resolution issue or a blocked domain. Test with a different domain, verify DNS settings, and consider switching to a more reliable DNS provider. Joining a public discord server a step by step guide: How to Find Public Discord Communities, Join Safely, and Participate
Can I set DNS on my router so all devices use it by default?
Yes. Changing DNS on your router affects all connected devices by default. It’s a quick way to enforce a single DNS for the entire network, but individual devices can still override if they’re configured to specific DNS servers.
Is there a risk of DNS hijacking?
Yes, if you’re on an untrusted network or if your router is compromised, DNS requests can be redirected. Protect your router with a strong admin password, keep firmware up to date, and consider using DoH/DoT where supported.
What’s the best DNS provider for gaming or streaming?
Latency matters most. Providers like Cloudflare and Google Public DNS often perform well in many regions, but latency varies by location. Test a couple of options from your home network to see what feels fastest in your area.
How do I revert to my ISP’s DNS if I don’t like the public option?
Return to DHCP-provided DNS or manually set the DNS back to the ISP’s primary and secondary addresses, then flush caches and reboot devices or the router to ensure changes propagate.
Do DNS changes affect VPN connections?
Some VPNs route DNS requests through the VPN tunnel. If you switch DNS while connected to a VPN, you may see DNS changes reflected inside the VPN or overridden by the VPN’s own settings. If you rely on VPN DNS for privacy, check your VPN provider’s documentation. How to create maintenance cleanup task in sql server a step by step guide
Can DNS changes improve privacy on mobile data networks?
Yes, using privacy-focused DNS providers and enabling DoH/DoT can reduce the amount of data your mobile carrier can observe about your DNS queries. However, always review the mobile provider’s policies and the app permissions you grant.
If you want a simple, practical takeaway: your primary DNS server is the first address listed under DNS Servers for your active connection. You can view it quickly, test it, and switch to a provider that better matches your speed and privacy needs. Keeping a basic awareness of DNS settings helps you troubleshoot faster when networks misbehave, and it lets you customize your online experience without getting bogged down in tech jargon.
