You can use CheckIP.

Hi!

Here you are:

http://nsis.sourceforge.net/Docs/AppendixE.html#E.3.16

VersionCompare YourIP 1.1.1.1 $var ; $var=1 Version1 is newer
- and -
VersionCompare YourIP 255.255.255.255 $var ; $var=2 Version2 is newer

might be a solution.

That won't work because 1.1.1.500 is "newer" than 1.1.1.1, but "older" than 255.255.255.255 and it's still invalid.

Hi!

As far as I can see CheckIP considers everything else than LanIP, APA or Loopback as an internet address. There's no validation.

Do you agree?

You're right. It doesn't really validate the IP. I've created ValidateIP which should take care of that.

Hi!

Perfect. Thank you very much!
