Before diving into the "how," let’s clarify the "why." DNS is often called the "phonebook of the internet." It translates domain names (like google.com) into IP addresses (like 142.250.190.46). Your ISP provides default DNS, but they are rarely the fastest or most private option.
What are you trying to solve? (high ping, slow speeds, blocked sites?) Are you using a custom SIM card from a specific carrier?
However, because the MC888 Pro is a 5G router, its overall speed is primarily constrained by cellular signal strength and tower congestion. DNS optimization provides a marginal but real improvement—akin to sharpening the focus on a camera rather than upgrading the lens. In practice, users in areas with weak 5G signals will see less benefit than those with strong, low-latency connections.
