Presentation

Ipcalc is a Ruby's gem that makes IP manipulation easier.

• Works with IPV4 and IPV6.
• Arithmetic operations (+, -, +=, -=). For example, if IP="1.2.3.4", then IP+1="1.2.3.5".
• Bitwise operations between IPs (|, &, ^).
• Left and righ shifts (<<, >>).
• Print IP in various formats:
  • The standard dotted notation. For example: 192.168.12.10
  • Decimal value. For example: 3232238602
  • Binary. For example: 11000000101010000000110000001010
  • Hexadecimal. For example: c0a80c0a
  • Pretty binary. For example: 11000000.10101000.00001100.00001010
  • Pretty hexadecimal. For example: c0.a8.0c.0a
• Subnet discovery. What is the "/23" subnet that contains this IP?
• Subnet testing. Is this IP included in this subnet?
• IP comparaison (>, <, >=, <=, ==, !=, <=>). For example: "1.2.3.4" > "1.2.3.5" : FALSE
• Manipulate IP like array. For examples, if IP="10.20.30.40":
  • IP[1] is 20.
  • IP[1] = 55, then IP="10.55.30.40"
• Create IPs from integers of strings.
