To find partial duplicates from a column, you can do as below:
1. Select a blank cell next to the IP, B2 for instance, and enter this formula =LEFT(A2,9), drag auto fill handle down to apply this formula to the cells you need. See screenshot:
2. Then go to next cell beside the formula1, C2 for instance, enter this formula =COUNTIF(B:B,B2), and drag fill handle over the cells you want. Then the result 2 (or other number bigger than 1) indicates the relative IP address are duplicates, 1 indicates unique. See screenshot:

- To post as a guest, your comment is unpublished.· 2 years agoThe information you provide is awesome. You often rank in the top 3 results on Google for the solutions I'm trying to find. Using your site drives me nuts though because I can't tell what is ads for your product and what is part of the solution. It drives me so nuts that I often leave your site to find the solution somewhere less frustrating. There's nothing separating the ads from the article and everything is the same font.
