Starting today, 2026-02-02, I have set up a repository to collect Bitcoin Core IP address manager (addrman) snapshots. These are collected daily from nodes via getrawaddrman. Historical snapshots are recorded in the Git history of the files.
For now, I include snapshots from the two https://demo.peer.observer nodes, which are generously sponsored by Localhost Research: a Bitcoin-Focused Research Center in the Bay Area.
The snapshots are licensed under the CC0 License and intended for researchers and engineers. Attribution is not required, but welcome.
