Local DNS Resolution

Evomi Residential Proxies offer local DNS resolution filtering to minimize DNS leak risks. This advanced privacy feature routes traffic through exit nodes that handle DNS queries locally, providing enhanced anonymity for security-conscious operations.

Understanding DNS Leaks

DNS leaks occur when your DNS queries bypass the proxy connection and use your real ISP’s DNS servers, potentially revealing your browsing activity and true location. This can compromise privacy even when using proxies, as websites can detect inconsistencies between your IP location and DNS resolver location.

How Local DNS Resolution Works

Our system attempts to resolve all DNS queries directly on exit nodes for maximum privacy. However, not all devices support this capability. When local DNS resolution is unavailable, queries fall back to our central servers.

The _localdns-1 parameter filters connections to only use exit nodes that support local DNS resolution, significantly reducing leak probability.

Implementation

Append _localdns-1 to your proxy password to enable local DNS resolution filtering:

http://testuser:[email protected]:1000

Examples

curl -x http://testuser:[email protected]:1000 https://ip.evomi.com/s

curl -x http://testuser:[email protected]:1000 https://ip.evomi.com/s

import requests

proxies = {
"http": "http://testuser:[email protected]:1000",
}
response = requests.get("https://ip.evomi.com/s", proxies=proxies)
print(response.text)

const fetch = require('node-fetch');

const proxyUrl = 'http://testuser:[email protected]:1000';
const url = 'https://ip.evomi.com/s';

fetch(url, { proxy: proxyUrl })
.then(res => res.text())
.then(body => console.log(body));

Security Considerations

While local DNS resolution significantly reduces leak risks, it’s not a 100% foolproof solution. Some edge cases may still occur:

• Exit nodes might use non-standard DNS configurations
• Network-level DNS interception could still happen
• Application-level DNS queries might bypass proxy settings

For maximum privacy, combine this feature with other security measures and DNS leak testing tools.

Common Use Cases

• Privacy Research: Minimize DNS fingerprinting risks
• Security Testing: Evaluate DNS leak protection systems
• Anonymous Browsing: Reduce location disclosure via DNS queries
• Competitive Intelligence: Prevent DNS-based activity tracking
• Compliance Operations: Meet strict privacy requirements
• Threat Research: Maintain operational security during investigations
