im trying to get an IP address range into an array so that i can scan for example 192.168.1.1 to 192.168.1.12 the array that i created was in vb6 and even that one errored out because of the "." between each octet..
Im not using vb6 anymore, just express
array for IP address range

Update on progress..
I added
ListBox1.Items.Add(currentAddress)
to the code and it seems that the output is only modifying the 3rd octet and outputing every loop to 255 on the 4th like so
staring ip address = 192.168.1.1
ending ip address = 192.168.8.14
scan begins/output
192.168.2.255
192.168.3.255
192.168.4.255
192.168.5.255
192.168.6.255
192.168.7.255
192.168.8.255
it needs to run all the way through from 1 to 255 the increment the 3rd octet and when the 3rd octet matches the 3rd octet from starting ip address, then the fourth should stop at 14 or whatever is listed..
nice job though gets me thinking on my feet
all and any replies are welcomed..Thanks

Hello. You should be able to add a range of ip addresses to a string array as follows:
Dim IpAddresses() As String = (New String() {"192.168.1.1", "192.168.1.2", "192.168.1.3"})

wow, alot cleaner then i expected..but none of the IPaddresses will be hardcodd, im guessing i can use a var for the addreses to scan
I need to be able to scan a range so, if the range was
192.168.1.1 to 192.168.3.14
i would need it to scan the ip address between that, also looking at the 3rd octet or second as well,so..that being said, it would scan upto 255 2 times and then upto 14 on the 3rd pass flagging the 3rd octet with each pass til it gets to 3..
I know this is a lil confusing..im more then confused..lol
Thank your for your time and knowlege sharing

Hi...
I think the following will work for what you're needing...might need to tweak it a bit here and there. Hope this helps!
Dim ipAddresses As New ArrayList Dim endAddress As String = "192.168.3.14" Dim currentAddress As String = "" Dim firstOctet As Integer = 192 Dim secondOctet As Integer = 168 Dim thirdOctet As Integer = 1 Dim forthOctet As Integer = 1 Do ' set the current ip addresscurrentAddress =
String.Format("{0}.{1}.{2}.{3}", firstOctet, secondOctet, thirdOctet, forthOctet) ' add the current ip address to the arrayipAddresses.Add(currentAddress)
' increment the third and forth octetsforthOctet += 1
If forthOctet > 255 ThenforthOctet = 1
thirdOctet += 1
End If Loop Until currentAddress = endAddress Dim addressArray() As String = ipAddresses.ToArray(Type.GetType("System.String"))Gmorken
Hi. I don't mean to be insulting but I don't think you're using the code correctly. Here I've updated this to add all of the items to a listbox as I believe you're doing. The results in my code look like exactly what you're looking for (I think.). Note that you don't have to add each item to the listbox individually you can add a range of ip addresses in a single line. I apologize in advance if I've simply misunderstood you.
ListBox1.Items.Clear()
Dim ipAddresses As New ArrayList Dim endAddress As String = "192.168.3.14" Dim currentAddress As String = "" Dim firstOctet As Integer = 192 Dim secondOctet As Integer = 168 Dim thirdOctet As Integer = 1 Dim forthOctet As Integer = 1 Do ' set the current ip addresscurrentAddress =
String.Format("{0}.{1}.{2}.{3}", firstOctet, secondOctet, thirdOctet, forthOctet) ' add the current ip address to the arrayipAddresses.Add(currentAddress)
' increment the third and forth octetsforthOctet += 1
If forthOctet > 255 ThenforthOctet = 1
thirdOctet += 1
End If Loop Until currentAddress = endAddressListBox1.Items.AddRange(ipAddresses.ToArray(Type.GetType(
"System.String")))Here is the list it produced
