About Net Neutrality Monitor

What the project does

Net Neutrality Monitor observes DNS resolution behaviour across a distributed set of probes and reports when responses diverge from the expected, neutral answer. The platform keeps an updated list of DNS servers under examination and records injected or blacklisted addresses identified during testing.

Coverage spans multiple countries, with country-specific reports highlighting which ISPs show signs of tampering, which categories of sites are affected, and how the situation evolves over time.

Net Neutrality Monitor is built around the idea that internet users deserve a clear view of how their connections are being shaped. The project watches how Internet Service Providers handle domain name resolution, paying close attention to whether responses are being altered, redirected, or quietly withheld. By comparing what comes back from different servers against the answers that should appear in a neutral network, the initiative highlights moments where ordinary traffic is being filtered or steered without the user's knowledge. The goal is simply to make those patterns visible and to keep the conversation about an open internet grounded in what is actually being observed on the wire.

The work is carried out by a distributed set of probes that act as quiet observers across multiple countries. Each probe asks a range of carefully chosen questions of nearby DNS resolvers and records the answers it receives, building a steady stream of evidence about how blocking, hijacking, and spoofing show up in practice. When a result looks suspicious, it is cross-checked against other probes and other servers to reduce the chance of false positives. The findings are then organized into country-specific reports and live dashboards, so visitors can quickly see which addresses appear to be under examination, which seem to be returning unexpected results, and how those patterns shift over time.

Everything produced by the project is published openly, because transparency only matters if the data itself can be inspected. Researchers, journalists, and curious members of the public can review the list of monitored servers, look at how individual probes are configured, and study the statistics that come out of continuous testing. The platform is run as a volunteer effort, supported by trusted community members and partner organizations who care about keeping the network honest. By sharing methods alongside results, the project aims to give anyone with an interest in net neutrality a reliable starting point for their own investigation, rather than a black box of unexplained claims.
