What I thought would be simple....

I'm looking for a free firewall that will allow me to block a list of IP ranges in long format? Is there anything of the type for windows?

What do you mean "long format"? You mean subnets? Networks? I am not a Windows user but, all Linux/Freebsd firewalls as well as Cisco, etc. So I would think the Windows ones would also.

IPs can be changed into integer values. This is an easy way of checking to see if an ip falls between a range. ipFROM (example 1003230032) ipTO (example 1123892933)

check out http://ip-to-country

Private Function ConvertToLong(ByVal IPAddress As Object) As Object

Dim x As Integer Dim Pos As Integer Dim PrevPos As Integer Dim Num As Integer

If UBound(Split(IPAddress, ".")) = 3 Then ' On Error Resume Next For x = 1 To 4 Pos = InStr(PrevPos + 1, IPAddress, ".", 1) If x = 4 Then Pos = Len(IPAddress) + 1 Num = Int(Mid(IPAddress, PrevPos + 1, Pos - PrevPos - 1)) If Num > 255 Then ConvertToLong = "0" Exit Function End If PrevPos = Pos ConvertToLong = ((Num Mod 256) * (256 ^ (4 - x))) + ConvertToLong Next End If

End Function
