IP Address

[anixon]

This IP address 1.a.1.1, 0.1.1.1, 1.1.1.1., 256,1,1,1 are processed by the following code as not being a valid ip address with the exception of this 1.1.0.1 which is captured as not being valid at Msgbox 1

CODE

$IPAddr = "1.1.0.1"

$Split = StringSplit($IPAddr, ".")

If $Split[0] = 4 Then

For $n = 1 To $Split[0]

$IP = $Split[$n]

If Not number($IP) and $IP <> "" Then

MsgBox(0,"1","Not an IP Address " & $IP)

ExitLoop

EndIf

If($IP < 0) Or ($IP > 255) Then

MsgBox(0,"2","Not an IP Address")

ExitLoop

EndIf

If ($n = 1) And ($IP = 0) Then

MsgBox(0,"3","Not an IP Address")

ExitLoop

EndIf

Next

Else

MsgBox(0,"4","Not an IP Address")

EndIf

Help is always appreciated Ant..

I dont get it, What are you trying to do?

let me see if I understand you, You have this String & you want to check if this string Contains any IP Adresses ? In this casse, can you post the Whole string , this piece is only a part of it right?

1.a.1.1, 0.1.1.1, 1.1.1.1., 256,1,1,1

An IP address can be any 4 groups number from 0 to 255 seperated with a "." with the exception of the first group which can be any number from 1 to 255. So I want to test each of the four groups to make sure that it is a valid number within the IP range so in the case of the first group it would be any number 1 to 255 in the second third and fourth groups it would be any number in any combination 0 to 255. None of the groupings can contain a non numeric alpha value [a-z]. That being the case 0.1.1.1 is not valid but 1.0.0.1 is also there can not be more than 4 groups so .1.1.1.1 is not valid and neither is 1.1.1.1. [because of the extra "."] or 0.1.1.1.1 or 1.1.1.1.0 because of the extra number group. So at both ends of the spectrum 1.0.0.0 to 255.255.255.255 is the valid range.

Arrhhh the magic of "StringIsInt" Ant..

[anixon]

This is the version that I settled on:

CODE

$iniIP = "1.1.1.256"

$ScriptDir = "C:\YourDirectory"

$DefaultPingID1 = "Router"

$DefaultPingIP1 = "192.168.0.1"

CheckIPAddr($iniIP,$scriptDir,"PingID1","PingIP1","Value",$DefaultPingID1,$DefaultPingIP1)

Func CheckIPAddr($IPAddr,$ScriptDir,$PingID,$PingIP,$Value,$DefaultPingID,$DefaultPingIP)

$Flag = 0

$Split = StringSplit($IPAddr, ".")

For $n = 1 To $Split[0]

$IP = $Split[$n]

If $Split[0] <> 4 then

$message = "Not [4] Groups of Numbers"

$Flag = 1

EndIf

If StringIsInt($IP) <> 1 Then

$Message = "Not a Number in a Group/s"

$Flag = 1

EndIf

If($IP < 0) Or ($IP > 255) Then

$Message = "2nd, 3rd or 4th Group Not 0-255"

$Flag = 1

EndIf

If ($n = 1) And ($IP = 0) Then

$Message = "1st Group is Not 1-255"

$Flag = 1

EndIf

If $flag = 1 then exitloop

Next

If $Flag = 1 Then

message("IP Address Error - " & $Message)

IniWrite($ScriptDir, $PingID,$Value, $DefaultPingID)

IniWrite($ScriptDir, $PingIP,$Value, $DefaultPingIP)

EndIf

If $flag = 0 Then

message("INI File CHECKED OK")

EndIf

EndFunc

Func message($Message)

msgbox(64," Error Message",$Message)

EndFunc

0.*.*.* is a valid IP address. By standards it's not used, but it is valid.

[anixon]

0.*.*.* is a valid IP address. By standards it's not used, but it is valid.

Thanks for that I was not aware.

I guess additional code will clean up the issue that would allow a user to use that combination [0.*.*.*]

Of course a coder at their option can increase the number of IP Tests to exclude any combination [valid or otherwise] as not being an address

that operates within their specific environment.

I hope you understood that * is a wildcard.

And yes, of course the code should always have the option. I was simply letting you know for completeness.

Very important information for those reading this forum. "completeness" a very important ingredient to good code practice
