anonymize_ip

This is a simple Python library for anonymizing IP addresses. Both IPv4 and IPv6 addresses are supported.

Examples:

• IPv4: 95.239.169.11 → 95.239.169.0
• IPv6: 5219:3a94:fdc5:19e1:70a3:b2c4:40ef:ae03 → 5219:3a94:fdc5:19e1::

Usage

pip install anonymizeip

from anonymizeip import anonymize_ip

address = "fe80::0202:b3ff:fe1e:8329"
anonymized = anonymize_ip(address)
print(anonymized)

# Prints "fe80::"

Settings

The number of address blocks that are set to 0 can be customized.

Besides the IP address, the function anonymize_ip takes two optional parameters:

anonymize_ip(
  address,
  ipv4_mask="...",
  ipv6_mask="..."
)

• ipv4_mask: Defaults to 255.255.255.0, i.e. the last octet will be anonymized (set to 0)
• ipv6_mask: Defaults to ffff:ffff:ffff:ffff:: (same as ffff:ffff:ffff:ffff:0:0:0:0), i.e. the last four blocks will be anonymized (set to 0)
