HighProxies Secure DNS Guide

DNS over TLS vs DNS over HTTPS: Secure DNS Setup Guide

Learn the difference between DNS over TLS (DoT) and DNS over HTTPS (DoH), choose the right encrypted DNS protocol, and configure a HighProxies secure DNS endpoint for your device or browser.

Secure DNS encrypts DNS requests between your device and the selected resolver. When you use a resolver near your proxy or VPN location, DNS responses and content delivery routing may also be more consistent with that location.

DNS Privacy Basics

Why Encrypted DNS Matters

Traditional DNS requests are commonly sent without transport encryption. This can expose the requested domain names to the local network, internet provider, or another system in the network path.

DNS over TLS sends DNS traffic through a dedicated encrypted channel, normally on port 853. DNS over HTTPS sends encrypted DNS requests through HTTPS, normally on port 443.

DoT and DoH protect the connection to the DNS resolver, but they do not make browsing anonymous. The resolver must still process each query, and encrypted DNS does not replace an HTTP/HTTPS proxy, SOCKS5 proxy, or VPN.

Protocol Comparison

DNS over TLS vs DNS over HTTPS

Both protocols encrypt DNS traffic. The better option depends on your operating system, browser, router, firewall rules, and whether you want device-wide or application-specific DNS control.

DNS over TLS

DoT normally uses TCP port 853. It is a practical choice for system-level encrypted DNS on supported Android devices, Linux systems, routers, and local resolvers.

DNS over HTTPS

DoH normally uses HTTPS on TCP port 443. It is supported by current browsers and operating systems, including Google Chrome and Windows 11.

Location-Aware Resolution

Selecting a DNS endpoint near your proxy or VPN location can help reduce DNS latency and avoid inconsistent content delivery routing.

Quick comparison
Choose DoT when

You want system-level secure DNS

Use DoT when the operating system, router, or resolver supports it and the network allows outbound connections on port 853.

Choose DoH when

You need browser support or port 443

Use DoH when it is supported by your browser or operating system, especially on networks where port 853 is unavailable.

Configuration Guide

How to Configure DNS over HTTPS and DNS over TLS

Use the instructions below as a starting point, then run a DNS leak test. Menu names and available options may differ by operating-system or browser version.

Windows 11: DNS over HTTPS

Open Network Settings

Open Settings > Network & internet, then select the active Wi-Fi or Ethernet connection.

Edit DNS Assignment

Find DNS server assignment, select Edit, choose Manual, and enable IPv4.

Enable Encrypted DNS

Enter the assigned resolver IP address, select the encrypted DNS option, add the matching DoH template when requested, and save the settings.

Android, Google Chrome, and Linux

Android Private DNS

Open Settings > Network & internet > Private DNS. Select the private DNS provider hostname option and enter the matching hostname, such as paris20-dns.highproxies.com.

Google Chrome DoH

Open Settings > Privacy and security > Security > Use secure DNS. Select a custom provider and enter a URL such as https://paris20-dns.highproxies.com/dns-query.

Linux with systemd-resolved

Confirm that your Linux distribution uses systemd-resolved. Set DNSOverTLS=yes in /etc/systemd/resolved.conf, configure the assigned resolver, restart the service, and test resolution.

Global Secure DNS Endpoints

Choose the hostname that corresponds with your assigned proxy or VPN datacenter. Endpoint availability may change, so confirm the correct resolver for your active service before production use.

Resolver Features

Secure DNS Performance and Privacy Features

HighProxies DNS endpoints support practical resolver features intended to improve repeated lookups, reduce unnecessary query disclosure, and keep resolution close to supported proxy locations.

Resolver Caching

Frequently requested DNS records can be served from cache until their valid time-to-live expires, reducing repeated upstream lookups.

QNAME Minimisation

QNAME minimisation reduces the amount of query information sent to upstream authoritative DNS servers where supported.

Location-Aware Resolution

Resolver placement near supported HighProxies datacenters can help DNS and content delivery responses remain consistent with the selected service location.

Troubleshooting

Secure DNS Frequently Asked Questions

Review common DNS over TLS, DNS over HTTPS, resolver location, encryption, and DNS leak questions.

Why does my connection fail after enabling DNS over TLS?

TCP port 853 may be blocked by your firewall, router, internet provider, or office network policy. If DoT is unavailable, try DNS over HTTPS on port 443 where your network policy permits it.

Does secure DNS hide queries from the DNS resolver?

No. DoT and DoH encrypt the network path between your device and the resolver. The resolver must still process the DNS query. Secure DNS improves transport privacy, but it does not guarantee anonymity.

Why does an IP checker show a different location?

Some test sites report DNS resolver, CDN, browser, or WebRTC information rather than only the proxy exit IP. Compare results from more than one tool and confirm that your browser, proxy, VPN, and DNS settings use the intended location.

How can I test whether DNS is encrypted?

Run a reputable DNS leak test after configuring DoT or DoH. The result should show the expected HighProxies resolver hostname or location instead of the DNS resolver supplied by your local internet provider.

What should I check first if DNS still leaks?

Check IPv6 and application-specific DNS settings. If secure DNS is configured only for IPv4, some systems may continue to use an IPv6 resolver. A browser, proxy client, or VPN application may also override the operating-system DNS configuration.

Should I use the DNS endpoint closest to me or to my proxy?

When you use a HighProxies proxy or VPN, choose the secure DNS endpoint associated with that service location unless support instructs you otherwise. This can provide more consistent DNS and content delivery routing.
