Convert an integer to IP string

Convert an integer to IP. I don't think you can do this with IPAddr, but I could be wrong

Edit, the original didn't work for low ranges.

And I was wrong about the IPAddr thing. I should have google'd better.

IPAddr.new(16909060, Socket::AF_INET).to_s

Ping a range of IP addresses

(1..254).each {|i| puts ": found 192.168.1.#{i}" if  `ping 192.168.1.#{i} -c 1 -w 1`.match(/ttl/) }

Format IPv4 address in octal binary format and vice versa (Ruby / Rails)

Format an IPv4 address like 192.168.1.1 in dotted binary format like 11000000.10101000.00000001.00000001
You also need this class: http://snippets.dzone.com/posts/show/2472
For Rails: Put this in your controller!

  # convert a dotted decimal IPv4 address to dotted binary format
  def ipv4_to_binary(ipv4addr)
    ia = ipv4addr.to_s.split('.')
    if ia.size != 4
      return "0.0.0.0"
    end
    output = ""
    i = 1
    for octett in ia
      output = output + octett.to_i.to_s(2).using("########","0",true)
      if i < 4
        output = output + "."
      end
      i += 1
    end
    return output
  end
  
  
  # convert a IPv4 adress in binary dotted format to a dotted IPv4 address
  def binary_to_ipv4(ipv4addr)
    ia = ipv4addr.to_s.split('.')
    if ia.size != 4
      return "0.0.0.0"
    end
    output = ""
    i = 1
    for octett in ia
      output = output + octett.to_s.to_i(2).to_s
      if i < 4
        output = output + "."
      end
      i += 1
    end
    return output
  end
