Hi all,

Got another question about the macro I'm writing. It's an IP address
database, the IPs are all listed in column A as such:

111.222.32.4
111.222.32.5
111.222.32.66
111.222.37.1
111.222.37.2
111.222.37.3
111.222.38.13
111.222.38.24
111.222.38.35

They are class B adresses, and the 3rd octet changes about 220 times
throughout the text files (here I show it change from 32 to 37 to 38).
I need to implement some steps which would open a new worksheet for
every new 3rd octet in the text file. I know I will end up with a
couple hundred sheets, but it's what my boss wants.

Any ideas are more than welcome.

Thanks in advance,

Roman

Assuming the IP's are column 1 and sorted on the 3rd octet:

Sub copyIP()
Dim sh As Worksheet, Startrow As Long
Dim lastrow As Long, v1, v, i As Long
Set sh = Worksheets("Data")
Startrow = 1
lastrow = sh.Cells(Rows.Count, 1).End(xlUp).Row
ReDim v1(0 To 3)
v1(2) = ""
i = 1
For i = 1 To lastrow
v = Split(sh.Cells(i, 1), ".")
If v(2) < v1(2) And i < 1 Then
Worksheets.Add After:=Worksheets(Worksheets.Count)
ActiveSheet.Name = v1(2)
sh.Range(sh.Rows(Startrow), sh.Rows(i - 1)).Copy _
ActiveSheet.Range("A1")
Startrow = i
End If
v1 = v
Next i
Worksheets.Add After:=Worksheets(Worksheets.Count)
ActiveSheet.Name = v1(2)
sh.Range(sh.Rows(Startrow), sh.Rows(lastrow)).Copy _
ActiveSheet.Range("A1")
End Sub

Thanks Tom. This line returns a run-time "subscript out of range" error
however:

Set sh = Worksheets("Data")


Thanks

I guess I should have said to change Data to reflect the name of the sheet
that contains your data, but I foolishly thought that would be obvious. My
Bad

Let me try again:

The following code is tested and worked with the data you showed and the
assumptions I previously stated. Make sure you change the sheet reference
(worksheets("Data")) to refer to the sheet that contains your data. I placed
your sample data on a sheet named DATA.

Sub copyIP()
Dim sh As Worksheet, Startrow As Long
Dim lastrow As Long, v1, v, i As Long

' change the next line to reflect the sheet that contains
' your data. for example, if your data was on a sheet
' with the name sheet1, the next line would actually be
' Set sh = Worksheets("Sheet1")
' I used the name Data for illustration

Set sh = Worksheets("Data") '<=== CHANGE

Startrow = 1
lastrow = sh.Cells(Rows.Count, 1).End(xlUp).Row
ReDim v1(0 To 3)
v1(2) = ""
i = 1
For i = 1 To lastrow
v = Split(sh.Cells(i, 1), ".")
If v(2) < v1(2) And i < 1 Then
Worksheets.Add After:=Worksheets(Worksheets.Count)
ActiveSheet.Name = v1(2)
sh.Range(sh.Rows(Startrow), sh.Rows(i - 1)).Copy _
ActiveSheet.Range("A1")
Startrow = i
End If
v1 = v
Next i
Worksheets.Add After:=Worksheets(Worksheets.Count)
ActiveSheet.Name = v1(2)
sh.Range(sh.Rows(Startrow), sh.Rows(lastrow)).Copy _
ActiveSheet.Range("A1")
End Sub

It's my fault Tom, don't worry, it is obvious that it has to change. I
figured I had to use the name of my excel file, which I tried, except I
entered the file name (dns.txt) instead of just the sheet name (dns).
That's where I got confused and posted back here. It works wonders now,
thanks very much again for the help, I appreciate it.
