sometimes when i import a macadres txt file, i get a duplicate macadres error. My problem is that i dont know what macadres is duuplicate; so when the import files exists of 100 macadresses, i have too check them 1 by 1. Isnt there a faster sollution??

Have you tied copying them into excel and filtering out the duplicates?
