VLSM Calculator

An IPv4 subnets calculator using original host, original subnet mask and desired subnet mask.

To Do List

• Clean up variable names (host vs network address confusion)
• Verify & correct subnet mask inversion -> broadcast address
• Build test cases
• Determine how to use subnets.py in relation to the for loop based on subnet count

Bug fixes

• convert_decimal(): "int() can't convert non-string with explicit base" when converting broadcast address
  fix: int(str(binary[]))
• invert_subnet_mask(): was returning 0 instead of inverted array & was checking if == 1 instead of '1'
