Create a 'helper column' in which you tease out the ISP. Ex: if the email
address is in A2, enter =RIGHT(A2,LEN(A2)-FIND("@",A2)) in B2 to calculate
just the ISP. Autofill that formula to each row, then sort based on the new
column.

to sort is by Ascending/descending and it sorts by the beginning of the text.
Thanks!
