I want to replace multiple numbers with asterisks with Notepad++, how to? Example:

109.169.76.0/22
109.169.88.0/21
109.190.0.0/16
109.196.166.0/23
109.196.172.0/24
109.196.175.0/24
109.200.30.0/23
109.200.192.0/21
109.200.208.0/20
109.201.133.22/32
109.201.133.24/32
202.55.45.41/32

109.196.***.***
109.196.***.***

If this is not too long to edit and it has the same amount of characters per line, you can do this using multiple cursors.

If the data you have follows a predictable pattern, then you can use that to replace everything after a specific character. This is shown here, alongside other helpful ways to edit or replace text.
