What Is a DNS Leak?
When you visit a website, your device asks a DNS server to translate the domain name to an IP address. A DNS leak sends these requests outside your VPN tunnel, letting your ISP see which sites you visit.

DNS leaks occur when your domain name queries bypass your VPN and go directly to your ISP. This exposes every website you visit, undermining the privacy your VPN is supposed to provide.

Misconfigured VPNs, IPv6 leaks, and operating system DNS settings can all cause leaks. Windows is particularly prone to DNS leaks due to Smart Multi-Homed Name Resolution which queries all available DNS servers simultaneously.
Use online DNS leak test tools to verify your VPN is properly routing DNS queries. If the test shows your ISP's DNS servers instead of your VPN provider's, you have a leak.
DNS leaks can reveal that you are using certain messaging platforms. WeTalkin's encrypted communication does not rely on DNS resolution that could expose your usage patterns to ISPs or network observers.

Configure your VPN to force all DNS through its tunnel. Use encrypted DNS providers like Cloudflare 1.1.1.1 or NextDNS. Disable IPv6 if your VPN does not support it.
DNS leaks could reveal connections to WeTalkin servers. Using encrypted DNS or a properly configured VPN prevents this metadata exposure.
DNS over HTTPS (DoH) encrypts DNS queries so your ISP cannot see which domains you resolve. It is a significant improvement over traditional plaintext DNS.
