§ bogon

bogon.

Drop in one or many IPs (v4 or v6, mixed); each gets classified against the IANA special-purpose registry. RFC 1918 / CGNAT / link-local / loopback / multicast / TEST-NETs / 6to4 / Teredo / ULA / GUA — the full set. Batch mode adds a per-class summary.

accepts

single IP (e.g. 8.8.8.8 or 2001:db8::1) or a list separated by whitespace, commas, or newlines.

complements /cidr

/cidr requires CIDR notation and does subnet math; /bogon takes raw addresses and only classifies. classifications are shared between the two via a common module.

use cases

triaging firewall log rows, sanity-checking IPs from a leak dump, distinguishing bogon source from real public traffic.
