  The InterPlanetary File System~(IPFS) is a popular decentralized peer-to-peer
network for exchanging data. While there are many use cases for IPFS, the
success of these use cases depends on the network. In this paper, we provide a
passive measurement study of the IPFS network, investigating peer dynamics and
curiosities of the network. With the help of our measurement, we estimate the
network size and confirm the results of previous active measurement studies.
