DNS Protocol Tunneling
Encapsulates your SSH traffic inside DNS query packets. Since DNS is essential for internet functionality, ISPs cannot block it without breaking their entire network infrastructure.
Bypass All DPI Systems
Successfully penetrates the most aggressive Deep Packet Inspection technologies. Works flawlessly on Axis, Telkomsel, XL, Indosat, and other restrictive ISPs that block conventional SSH/VPN protocols.
Universal Compatibility
Works on UDP port 53 which is never blocked by any network. Compatible with all Android SSH clients, HTTP Injector, HTTP Custom, and v2rayNG with DNS tunnel mode enabled.
Why Choose SSH SlowDNS?
The bypass master for restrictive networks in 2026
Unblockable by Design
DNS is a fundamental internet protocol. Blocking DNS queries would disable domain name resolution entirely, making websites inaccessible. ISPs physically cannot block SlowDNS without breaking their service.
Perfect for Mobile Users
Specifically optimized for mobile internet connections where DPI is most aggressive. Excellent performance on 4G/5G networks from Axis, Telkomsel, XL, Indosat, Tri, and Smartfren.
Stable Low-Latency
Despite the name "Slow" DNS, our optimized implementation provides stable connections suitable for browsing, streaming, and even light gaming. UDP protocol ensures minimal overhead.
Free Quota Friendly
Works excellently with operator free quota packages (kuota gratis) and promotional data plans. DNS traffic often bypasses quota restrictions on certain networks.

Understanding SSH SlowDNS Technology
SSH SlowDNS is a specialized tunneling technique that encapsulates SSH traffic within DNS query and response packets. The "slow" in its name refers to the original implementation's bandwidth limitations, but modern optimizations have significantly improved performance while maintaining the core bypass capabilities that make this protocol invaluable.
The fundamental principle behind SlowDNS effectiveness is simple: DNS is non-negotiable for internet functionality. When you type a website address, your device sends a DNS query to resolve that domain name into an IP address. Without DNS, the internet becomes essentially unusable. This makes DNS traffic the last thing any ISP or network administrator can afford to block, even in heavily censored environments.
Deep Packet Inspection systems can easily identify and block conventional SSH, OpenVPN, or WireGuard traffic based on their distinctive packet signatures. However, when SSH traffic is fragmented and encapsulated inside DNS queries, it becomes completely indistinguishable from legitimate DNS resolution requests. DPI systems cannot block this traffic without also blocking all DNS queries, which would render the entire network non-functional.
This makes SlowDNS particularly effective in Indonesia and other markets with aggressive ISP traffic management. Mobile operators like Axis, Telkomsel, XL, and Indosat deploy sophisticated DPI systems to control bandwidth and restrict VPN usage, but these systems are powerless against properly implemented DNS tunneling. SlowDNS also works well with "kuota gratis" (free quota) packages that many Indonesian operators provide, as DNS traffic sometimes bypasses quota restrictions.
Our SlowDNS servers utilize optimized UDP-based DNS tunneling on port 53 (standard DNS) and port 5300 (custom nameserver), with custom NS records for maximum compatibility. Each account supports unlimited bandwidth, 3-day active period, and simultaneous connections from up to 2 devices. Compatible with HTTP Injector, HTTP Custom, SSH tunneling apps, and any client that supports SlowDNS protocol.
