mmIP

The calculator recognizes IP address from the text. Unlike with others, you don't need to jump to four different (period separated) fields. Just past it in, don't worry about leading/trailing spaces and characters. Input such as 'This is my IP address: 192.168.1.1!' is not an issue; the program will remove all other characters and format the IP address automatically. Also if you got bored of writing out all '0' fields, don't worry--'10...1' will translate as '10.0.0.1', same way '10.' will translate to '10.0.0.0'. But this tool goes even farther: CIDR mask can be part of your entry as well. For example, string like '10.0.0.0/24' will reflect Netmask settings too. And yes, if you enter 'Say hi to my 10th laptop/with 8 cores.' you will get '10.0.0.0' /8.
