Zero speed loss: why streams run at full quality

A common worry with region-unlocking tools is buffering and reduced picture quality. SmartDNS avoids this entirely because it does not tunnel your traffic. Only the initial DNS lookup — the tiny request that translates a domain name into an IP address — passes through our UK infrastructure. Once the connection is established, the actual video data travels directly from the streaming server to your device at full speed.

There is no encryption overhead, no VPN tunnel and no re-routing of your bulk traffic through a distant server, which is what slows a traditional VPN down. The result is 0ms of added latency to your streams and no buffering penalty, so 4K and HD content plays exactly as it would without SmartDNS.
