# Offline prefix table for the observer's peer-address column (ledger X5 and X14, O-X.1 (a)).
# One row per line: <IPv4 prefix in CIDR> <ASN> [name]. Longest prefix wins. Private and loopback ranges answer
# "local" without a row. IPv6 is not read yet. The observer never asks a third party at run time; this file is the
# lookup. Fill it from a BGP dump taken by hand (RIPEstat, Team Cymru's whois bulk service, or a pyasn dump of the
# RouteViews RIB), with the dump's date on the line, and commit the file. Empty tonight (5 October 2026): no row is
# written from memory, so every public peer reads source 'none' until a dump is loaded.
