The data embedded is from the latest ASMap file from the asmap-data
repository: https://github.com/asmap/asmap-data/blob/main/1755187200_asmap.dat
What changed, and why it matters
This commit adds a new binary data file containing an internet routing map (ASMap data) used by Bitcoin Core to group IP addresses by their network owner. It is a build/data-only change with no code modifications. There is no indication of a security vulnerability, bug fix, or malicious content in the commit itself.
No security action required. If desired, verify the SHA-256/checksum of the added ip_asn.dat file against the upstream asmap-data release at https://github.com/asmap/asmap-data/blob/main/1755187200_asmap.dat to confirm supply-chain integrity.

Evidence from the diff
Commit 634cd60dc8f646b25701c45ac35a1175ce4c4da9 introduces src/node/data/ip_asn.dat, a binary ASMap dataset sourced from the public asmap-data repository. The diff only shows the addition of this binary file; no executable code, build scripts, or configuration logic is changed. ASMap data is used for peer bucketing by autonomous system to improve network topology diversity. The content of the binary file cannot be meaningfully reviewed from the diff alone, but the provenance is stated in the commit message.
