cached-ipaddress

library1.1.2pypypi✓ verified 81d ago

A thin caching wrapper around Python's ipaddress module that memoizes construction of IPv4Address, IPv6Address, IPv4Network, IPv6Network, and IPv4Interface/IPv6Interface objects to reduce overhead when the same addresses are parsed repeatedly. Current version 1.1.2, maintained actively, supports Python >=3.9.

ipaddress

✓ from cached_ipaddress import ipaddress

✗ from cached_ipaddress import CachedIPv4Address

Import and use a cached IP address object. The caching is internal; no manual setup required.

from cached_ipaddress import CachedIPv4Address # Create a cached IPv4 address addr = CachedIPv4Address('192.168.1.1') print(addr) # 192.168.1.1 # Same string returns cached object (id may differ but equality holds) addr2 = CachedIPv4Address('192.168.1.1') print(addr == addr2) # True

Known issues

gotchaCached objects are not singletons across string values; they are only cached per string argument, but multiple calls with the same string may return different instances if the cache is cleared or if using different constructors (e.g., CachedIPv4Address vs ipaddress.IPv4Address).

fix

Use identical constructor for caching benefit; do not assume object identity with `is`, rely on `==`.

affects: all

gotchaThe cache is unbounded and stored in a dictionary keyed by the string representation. In long-running processes with many unique addresses, memory usage may grow without bound.

fix

Consider periodic cache clearing or using a bounded cache if memory is a concern (not built-in).
