This dataset maps the network layer of the Invisible Internet Project (I2P), collected using the SWARM-I2P framework, which deployed I2P routers as mapping agents. It documents over 50,000 nodes with metrics such as bandwidth, latency, and uptime, plus network traffic records and geographic distribution. Node identifiers were anonymized. Data is available in CSV and TXT formats on Zenodo, with mapping scripts on GitHub.
