I have created an IP address calculator. It’s calculating network- and host address, shows weather an optional 2nd address is local or remote. Output is decimal, hexadecimal and binary. It will tell you, if an IP address is valid or not (i.e. 172.16.253.0 / 24 is invalid while 172.16.253.0 / 23 would be valid; 127.255.255.254 is a loop-back address, 169.254.15.2 is an APIPA address and many more)
My intention was, to teach my daughter understanding IP addresses. Feel free linking to my calculator or post it on Facebook / Twitter / …
Tell me if there is a bug in it! Thanks 😉
