iptocc 3.1.1

Fast, offline IP-to-country lookup. Python bindings over the Rust iptocc crate.

iptocc

Fast, offline IPv4/IPv6 to ISO 3166-1 alpha-2 country code lookup for Python.

[!IMPORTANT] iptocc 3.0 is a complete Rust rewrite. Versions 2.x and earlier were pure-Python on top of pandas. The public API stays mostly compatible (see migration notes below), single-lookup latency dropped from ~78 ms to ~100 ns, and a batch API was added. IPv6 is still supported.

Features

• Offline lookup, no API keys, no network calls
• IPv4 and IPv6 in one call
• Single string OR batch (any iterable of strings)
• Lookup data embedded in the wheel; no runtime file I/O
• iptocc CLI installed alongside the library
• Database refreshed nightly from the five Regional Internet Registries

Install

Requires Python 3.10 or newer.

pip install iptocc

Usage

from iptocc import country_code

country_code("8.8.8.8")                       # "US"
country_code(["8.8.8.8", "1.0.16.1"])         # ["US", "JP"]

A CLI is installed alongside the library:

$ iptocc 8.8.8.8 1.0.16.1
8.8.8.8 US
1.0.16.1 JP

Migrating from 2.x

# 2.x
from iptocc import get_country_code, CountryCodeNotFound
try:
    cc = get_country_code("8.8.8.8")
except CountryCodeNotFound:
    cc = None

# 3.x
from iptocc import country_code
cc = country_code("8.8.8.8")  # returns None on miss
