Replacing numbers with asterisks

Question

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

should become:

109.169.***.***
109.169.***.***
109.190.***.***
109.196.***.***
109.196.***.***
109.196.***.***
109.200.***.***
109.200.***.***
109.200.***.***
109.201.***.***
109.201.***.***
202.55.***.***

(Sorry if I didn't describe it clearly, but I want to replace anything after "NNN.NNN" with "***.***" (N is number) Thanks :)
