Secure DNS Guide: Configure DoT & DoH in 2026
Protect DNS requests between your device and resolver by using DNS over TLS (DoT) or DNS over HTTPS (DoH) with HighProxies endpoints and location-aware proxy workflows.
Why Secure DNS Still Matters
Standard DNS is usually sent without encryption. That means DNS queries can be exposed to the local network, upstream provider, or any system sitting in the request path.
Secure DNS helps reduce that exposure by encrypting the DNS transport layer. DoT uses a dedicated encrypted DNS channel, while DoH carries encrypted DNS requests over HTTPS.
For customers using social media proxies, premium SOCKS5 proxies, or private proxies, matching DNS resolution with the correct proxy location helps keep routing cleaner and more predictable.
DoT vs DoH: Which One Should You Use?
Both options encrypt DNS traffic. The right choice depends on your device, network rules, and whether you want system-level or browser-level DNS control.
DNS over TLS
DoT uses port 853 and is a clean option for system-level DNS encryption on Android, Linux, routers, and resolver-based setups.
DNS over HTTPS
DoH uses HTTPS on port 443 and is widely supported by browsers and newer operating systems, including Windows 11 and Chrome.
Proxy-Friendly Routing
Using a DNS endpoint near your proxy location helps reduce odd CDN routing, slow lookups, and location mismatch warnings.
Step-by-Step Configuration Guide
Use these settings as a practical starting point. Always test after changes because local networks, browsers, and operating systems handle secure DNS differently.
Windows 11 Setup: DNS over HTTPS
Open Network Settings
Go to Settings > Network & internet and select your active Wi-Fi or Ethernet connection.
Edit DNS Assignment
Find DNS server assignment, click Edit, choose Manual, and enable IPv4.
Enable Encrypted DNS
Enter the preferred DNS IP, choose encrypted-only DNS over HTTPS, and add your HighProxies DoH endpoint URL.
Mobile, Browser, and Linux Setup
Android Private DNS
Open Settings > Network & Internet > Private DNS. Select Private DNS provider hostname and enter the matching HighProxies hostname, such as paris20-dns.highproxies.com.
Google Chrome DoH
Open Settings > Privacy and security > Security > Use secure DNS. Select Custom and enter a DoH URL such as https://paris20-dns.highproxies.com/dns-query.
Linux DoT
Edit /etc/systemd/resolved.conf, set DNSOverTLS=yes, and point DNS to your assigned HighProxies resolver IP.
Global Secure DNS Endpoints
Choose the endpoint closest to your proxy location for lower latency and more consistent location-aware routing.

Important: endpoint availability can change. For production use, match the DNS endpoint with the active datacenter assigned to your proxy or VPN service.
High-Performance DNS Features
HighProxies DNS endpoints are designed for reliable proxy and VPN workflows, with practical resolver features that support speed, privacy, and cleaner routing.
Resolver Caching
Frequently requested records can be served from cache, reducing repeated lookup time for common domains and applications.
QNAME Minimisation
QNAME minimisation reduces the amount of query detail sent to upstream authoritative servers where supported.
Location-Aware Routing
Resolver placement near HighProxies datacenters helps keep CDN responses aligned with the proxy location you are using.

Secure DNS FAQ and Troubleshooting
These are the most common issues when switching from plain DNS to DoT or DoH.
Why does my connection fail after enabling DNS over TLS?
Port 853 may be blocked by your local firewall, router, network provider, or office network policy. In that case, try DNS over HTTPS on port 443 where permitted.
Does secure DNS hide traffic from the DNS resolver?
No. DoT and DoH encrypt the transport path between your device and the resolver. The resolver still has to process the DNS query. Secure DNS improves transport privacy; it is not a guarantee of anonymity.
Why does an IP checker show a different location?
Some IP checkers show DNS resolver, CDN, browser, or WebRTC details rather than the actual proxy route. Test with more than one tool and confirm that your browser, proxy, and DNS settings are aligned.
How can I test if DNS is encrypted?
Run a DNS leak test after configuring DoT or DoH. The result should show the expected HighProxies DNS hostname or resolver location, not your local ISP resolver.
What should I check first if DNS still leaks?
Check IPv6. If IPv6 is enabled but secure DNS is only configured for IPv4, some systems may still send DNS queries through the unencrypted IPv6 path.
