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.
