How to fill down IP Address with increment in Excel?

Sometimes you may need to assign IP addresses to your colleagues, for example, the range of IP address may range from 192.168.1.1 to 192.168.10.1. What can you generate them easily? In fact, the Auto Fill feature does not solve this problem, or you can create them manually by typing them one by one? This vedio will recommend you two methods to fill in IP address with increment in Excel.

Fill down IP Address with increment with formulas

If you want to generate the range of IP Address from 192.168.1.1 to 192.168.10.1 (the increment number locates in the third octet), the following formula will help you.

1. Select a blank cell (says cell B2), enter the below formula into it and then press the Enter key.

="192.168."&ROWS(\$A\$1:A1)&".1"

2. Then you can see the first IP Address is created, select this cell, drag its Fill Handle down to the cell until all needed IP Addresses are created.

Notes:

1. In the formula, 192, 168 and 1are the first two octet and the last octet of the IP Address. A1 means that the row number of this cell is extracted as the third octet of the IP Address. If the third octet number begins with 3, A1 should be changed to A3, and the \$A\$1 is a constant, you needn’t change it.
2. For generating IP Addresses increment the first octet, please use this formula:
=&ROWS(\$A\$1:A192)&".168.2.1"
3. For generating IP Addresses increment the second octet, pleas apply this formula:
="192."&ROWS(\$A\$1:A168)&".1.1"
4. And for generating IP Addresses increment the fourth octet, this formula will work.
="192.168.1."&ROWS(\$A\$1:A1)
