It shows you how to add multiple IP's and it shows how to include an IP range. For you, it would look something like this:
^202\.71\.149\.126 $ ¦ ^61\.8\.147\.(9[8-9]¦10[0-4])$
The first expression is a single IP and the second expression takes care of the range. You have a range in the 90's and a range in the 100's.
