In extreme network censorship environments, when all conventional VPN protocols (such as WireGuard, VLESS, or Shadowsocks) are accurately identified and blocked, DNS tunneling often becomes the "last resort."

Today, we're featuring MasterDnsVPN (GitHub 6.1k Stars), an open-source project that pushes this classic technique to a new level. It not only excels in stability but also completely outshines traditional projects like DNSTT and SlipStream in terms of speed and efficiency.

Why DNS Tunneling?

DNS (Domain Name System) is the bedrock of the internet. Almost all firewalls allow DNS traffic to pass; otherwise, the entire network would be paralyzed. DNS tunneling encapsulates TCP data within standard DNS queries and responses, disguising it as normal domain resolution traffic to pierce through the harshest censorship.
