Hello Experts

I have two files file1 and file2, both have IP addresses.
Basically i want a comparison in which i can get any new IPs present in file2 when compared it with file1 and viceversa.

Example:
File1
172.30.80.1
172.30.80.2
172.30.80.3
172.30.80.21

172.30.80.23
172.30.80.25
172.30.80.27
172.30.80.28
172.30.80.29...
