Hello everybody

Can you guys help me find a way to get the third octet from an IP address?
What i basically need is everything that is in between (but not including) the second and third dot (.).

Examples:

192.168.12.77
172.16.215.33
10.0.1.1

I should get the following:
12
215
1

Thank you :)

Would this help?
Sub Sample()
    Dim strIP As String, MyArray() As String
    
    strIP = "192.168.12.77"
    
    MyArray = Split(strIP, ".")
    
    MsgBox MyArray(2)

Here's a formula suggestion:

=LEFT(MID(A1,FIND(".",A1,FIND(".",A1)+1)+1,99),FIND(".",MID(A1,FIND(".",A1,FIND(".",A1)+1)+1,99))-1)

start in row 1 and copy down

cheers, teylyn

Building on SiddhartRout's VBA suggestion: if you want a dynamic VBA solution, you could try this user defined formula

Function Sample(strIP As String)
    Dim MyArray() As String
    MyArray = Split(strIP, ".")
    Sample = MyArray(2)
End Function

Open in new window


Copy and paste the code into a regular code module and then use

=sample(A1)

to calculate the result.

=TRUNC("0"&MID(A1,FIND("|",SUBSTITUTE(A1&"..",".","|",2))+1,10))

Won't get any #value #n/a errors if it is not a valid ip address, 0 instead

Nevermind, please ignore the previous comment. Been working at it too long - there are better answers.

CK, nice one with the TRUNC. It does work for my data sample, so no need to apologize.

Try

=TRIM(LEFT(RIGHT(SUBSTITUTE(A1,".",REPT(" ",9)),18),9))

...or....

=INT(-LOOKUP(0,-RIGHT(A1,{1,2,3,4,5,6,7})))

Thank you all for your suggestions.

I've managed to get something working from cyberkiwi's formula.
I ran into issues regarding international/regional settings when trying to use an unmodified version of cyberkiwi's.
Truncate expects a number, but on my danish version of Excel it does not see the preliminary result (on which to truncate) as a number. Yay! :/

Here is what I got to work:

=MID(B9;FIND("|";SUBSTITUTE(B9 & "..";".";"|";2))+1;FIND("|";SUBSTITUTE(B9 & "..";".";"|";3))-FIND("|";SUBSTITUTE(B9 & "..";".";"|";2))-1)

Thank you cyberkiwi (and all others as well) :)

Had to modify the suggestion due to regional differences between the two computers.

Though I am happy for the points, I thought the other formulas worked as well.
Barry has a knack for formulaes, and his two options are both amazing pieces of art.

While the 2nd one returns the wrong result when the fourth octet is 0, I think the 1st one works.
