MikroTik

MikroTik routers use the open-source RouterOS operating system, which provides routing, wireless networking, and firewall services for home and small office networks.

Configure DNS-over-HTTPS​

  1. Access your MikroTik router:
    • Open your web browser and go to your router's IP address (usually 192.168.88.1)
    • Alternatively, you can use Winbox to connect to your MikroTik router
    • Enter your administrator username and password
  2. Import root certificate:
    • Download the latest bundle of trusted root certificates: https://curl.se/docs/caextract.html
    • Navigate to Files. Click Upload and select the downloaded cacert.pem certificate bundle
    • Go to System → Certificates → Import
    • In the File Name field, choose the uploaded certificate file
    • Click Import
  3. Configure DNS-over-HTTPS:
    • Go to IP → DNS
    • In the Servers section, add the following AdGuard DNS servers:
      • 94.140.14.49
      • 94.140.14.59
    • Set Allow Remote Requests to Yes (this is crucial for DoH to function)
    • In the Use DoH server field, enter the URL of the Private AdGuard DNS server: https://d.adguard-dns.com/dns-query/*******
    • Click OK
  4. Create Static DNS Records:
    • In the DNS Settings, click Static
    • Click Add New
    • Set Name to d.adguard-dns.com
    • Set Type to A
    • Set Address to 94.140.14.49
    • Set TTL to 1d 00:00:00
    • Repeat the process to create an identical entry, but with Address set to 94.140.14.59
  5. Disable Peer DNS on DHCP Client:
    • Go to IP → DHCP Client
    • Double-click the client used for your Internet connection (usually on the WAN interface)
    • Uncheck Use Peer DNS
    • Click OK
  6. Test and verify:
    • You might need to reboot your MikroTik router for all changes to take effect
    • Clear your browser's DNS cache. You can use a tool like https://www.dnsleaktest.com to check if your DNS requests are now routed through AdGuard
