IPv4Helper

Handle and manipulate IPv4 CIDRs in a simple fashion, including generating CIDR ranges and viewing general subnet information.

Installation

pip install ipv4helper

Usage

Provide an IPv4 address, and optionally the CIDR it resides in (otherwise "/32" will be appended to the given IP).

from ipv4helper import IPv4Helper
i = IPv4Helper("127.144.4.9/28")
print(i.subnet_summary)
for x in i.ip_range_generator():
	print(x)

# snipped output

Integration with IPv4Mutate GitHub PyPi

from ipv4helper import IPv4Helper
from ipv4mutate import IPv4Mutate
i = IPv4Helper("127.144.4.9/28")
for x in i.ip_range_generator():
	z = IPv4Mutate(x)
	print(z.mutate_hex)

# snipped output
# ...
# 0x7f.0x90.0x4.0x0
# 0x7f.0x90.0x4.0x1
# 0x7f.0x90.0x4.0x2
# 0x7f.0x90.0x4.0x3
# ...

Important Notes

• "/0" is not supported in this version, but it will be "soon"

TODO

• better internal naming convention
• /0 support
• integrate with IPv4Mutate and IPv6Helper
