fipv (fast ip validator) is a python package build with C language. Simply it includes basic IP address validator functions as a C function, so works faster than others. Following C functions avaliable on this package:

  • ipv4
  • ipv4_cidr
  • ipv6
  • ipv6_cidr

Can be used on bulk IP data. You can find detailed test benchmark at below.


fipv can be installed easly with pip3. It requires Python 3.7+

$ pip3 install fipv



import fipv

# Basic C validation functions
    fipv.ipv4(''),  # True
    fipv.ipv4_cidr(''),  # False
    fipv.ipv6('::1'),  # True
    fipv.ipv6_cidr('::1/129'),  # False

# Validate bulk IPv4 data
ips = [''] * 1000000
valids = [ip for ip in ips if fipv.ipv4(ip)]
print(len(valids))  # 1000000

Test Benchmark (2021-10-07)

In this test, it was tested validation speed and average RAM usage with different python validators and different data types. Finally results saved to below table.

Test Duration: Used linux time command for determine execution time of script.
Avr. RAM Usage: Used linux ps command every 0.1 second and calculated RAM average.
