What happens when DNS service is down? I have ControlD Family Friendly free DNS service in Network Adapter on Windows 11 and its DoH DNS in AdGuard Pro on the iPad. Would the internet stop working if the ControlD service was down? If not, what can you do to achieve this?

When the DNS (Domain Name System) service is down, it can have various impacts on your internet connectivity and browsing experience. Here are some possible scenarios and solutions related to your setup:
1. **Impact on Internet Connectivity**:
- If the DNS service provided by ControlD Family Friendly or AdGuard Pro is down, your devices may have trouble resolving domain names to IP addresses. This means that you might not be able to access websites by their domain names (e.g., www.example.com).
- Your internet connection may still be active, but you may experience delays or timeouts when trying to access websites due to the DNS resolution issues.
2. **Fallback DNS Servers**:
- To mitigate the impact of a DNS service outage, you can configure fallback DNS servers on your devices. Fallback DNS servers are alternative DNS servers that your devices can use if the primary DNS service is unavailable.
- In Windows 11, you can configure multiple DNS servers in the Network Adapter settings. By adding backup DNS servers (e.g., Google DNS, Cloudflare DNS) alongside ControlD Family Friendly, your device can switch to these servers if ControlD is down.
- Similarly, in AdGuard Pro on your iPad, you can configure additional DNS servers to serve as backups in case the primary DoH DNS service is unavailable.
3. **Local DNS Resolver**:
- Another approach is to set up a local DNS resolver on your network, such as Pi-hole or BIND DNS server. These local DNS resolvers cache DNS records and can provide DNS resolution even if the external DNS service is down.
- By pointing your devices to the local DNS resolver as the primary DNS server, you can ensure that DNS queries are resolved within your network even if the external DNS service is unavailable.
4. **Testing and Monitoring**:
- Regularly testing the DNS resolution on your devices can help you identify issues with the DNS service promptly. Tools like nslookup or dig can be used to manually check DNS resolution.
- Monitoring services can also be set up to alert you when the DNS service is down, allowing you to take action proactively.
In conclusion, while the internet may not completely stop working if the DNS service is down, you may experience disruptions in accessing websites. Configuring fallback DNS servers, setting up a local DNS resolver, and monitoring the DNS service can help mitigate the impact of DNS outages and ensure a more reliable internet connection.

#### 2. DoH DNS Services in Wi-Fi Hardware Properties:
- Press `Win + X` and select "Windows Terminal (Admin)" to open PowerShell with administrative privileges.
- Run the following command to set up DoH DNS for your Wi-Fi connection:
```powershell
Set-DnsClientServerAddress -InterfaceAlias "Wi-Fi" -ServerAddresses "DoH_DNS_Server_IP"
```
Replace `"Wi-Fi"` with the name of your Wi-Fi interface and `"DoH_DNS_Server_IP"` with the IP address of the DoH DNS server you want to use.
### Setting Up DoH DNS Services in AdGuard Premium:
#### 1. Configuring DoH DNS in AdGuard Premium:
- Open AdGuard Premium on your device.

When setting up multiple DNS over HTTPS (DoH) server addresses in the Wi-Fi adapter properties on Windows 11, you should separate the IP addresses of the DNS servers with a comma, not a semicolon. Using a comma is the correct way to specify multiple DNS server addresses in this context.
By separating the DoH server addresses with a comma, you are indicating to the system that these are distinct server addresses that should be used as part of the DNS resolution process. This allows you to configure multiple DoH DNS servers for redundancy and load balancing, ensuring that if one server is unavailable, the system can automatically switch to another specified server for DNS resolution.
Therefore, when manually configuring multiple DoH DNS server addresses in the Wi-Fi adapter properties, remember to separate them with a comma to ensure that the settings are correctly applied and that your system can utilize the specified DNS servers effectively.

- Click "OK" to save the changes.
6. **Apply Changes**:
- Close all windows and restart your Wi-Fi connection to apply the new DNS settings.
By following these steps and entering the IP addresses of different DoH DNS servers separated by a comma in the Wi-Fi adapter properties, you can configure multiple DoH templates for different DNS servers.

Yes, although DNS provice an alternative server, It has happened that ISP DNS services were under attack and domain name requests are not resolved to IP-addresses.
In stead of specifying multiple it is easier to follow the hierarchy of applying the correct DNS and define a backup at lower level.
When you have a laptop can can set a fallback DNS for your network Adapter. I also have set one in the router. Why would you switch DNS on the fly?
I use NextDNS in my browser, Quad9 set in the laptop adapter and DNS0.eu in the router.

- DNS/DOH set in your browser
- DNS/DOH set in the (e.g. Wifi) network connection on your PC or DNS set for the network adapter (all connections) on your PC
- DNS set in your router.

- Locate either "Internet Protocol Version 4 (TCP/IPv4)" or "Internet Protocol Version 6 (TCP/IPv6)," depending on your network configuration, and select it.
- Click on the "Properties" button.
5. **Enter DoH Templates**:
- In the Properties window, look for the option related to setting DNS servers manually.
- Enter the DoH templates for Cloudflare and Google in the appropriate fields:
- For Cloudflare: `https://cloudflare-dns.com/dns-query`
- For Google: `https://dns.google/dns-query`
- Separate the two URLs with a comma or any other appropriate delimiter.
6. **Apply Changes**:
