poptrie 0.4.3

High-performance IP and country lookup backed by Rust poptrie

poptrie

High-performance IP lookup backed by Rust. This public repository owns the final Python facade and publishes wheels.

Stable public contract:

• from poptrie import IpSearcher
• IpSearcher resolves to poptrie.ip_searcher.IpSearcher
• native extension details are intentionally hidden behind the facade

Installation

Install from PyPI:

pip install poptrie

Usage

import socket
from pathlib import Path

from poptrie import IpSearcher


bin_path = Path("china-ip.bin")
searcher = IpSearcher(bin_path)

print("1.0.1.1" in searcher)
print(searcher.contains_ip("1.0.1.1"))
print(searcher.lookup_country("1.0.1.1"))
print(searcher.is_china("1.0.1.1"))

ips = ["1.0.1.1", "8.8.8.8", "240e::1", "2001:db8::"]
print(searcher.contains_ips(ips))
print(searcher.lookup_countries(ips))
print(searcher.matches_countries(ips, "CN"))

v4_ips = ["1.0.1.1", "8.8.8.8", "110.16.0.1", "127.0.0.1"]
packed_v4 = b"".join(socket.inet_pton(socket.AF_INET, ip) for ip in v4_ips)
print(searcher.contains_packed(packed_v4, is_v6=False))
print(searcher.lookup_countries_packed(packed_v4, is_v6=False))
print(searcher.matches_country_packed(packed_v4, "CN", is_v6=False))

Example

python example.py

Tests

Public facade verification:

python -m unittest discover tests

Notes

• Country lookups are resolved in Rust and exposed as 2-letter strings in Python.
• *_packed methods are intended for high-throughput byte-oriented workloads.
• The public Python facade lives in poptrie/__init__.py and poptrie/ip_searcher.py.
• Files such as *-overlap.csv are input conflict audit reports, not evidence that the final .dat files still contain overlapping CIDRs.
