Top mode (default)

Default top mode counts occurences of each IP address and print top N (10) results.

$ topip /var/log/mail.log
...
    8405 92.155.149.266
    8496 35.142.45.298
   66340 127.0.0.1

or via stdin, something like:

grep "SASL LOGIN authentication failed:" /var/log/mail.log | topip

use -t N to override default number of lines (10).

Grep mode

Grep mode activated with -g or -i keys. -g print whole lines which has any IP address, -i print only IP addresses.

Just grep all lines when we have IP:

# topip -g /var/log/mail.log
Oct  9 05:48:25 mx postfix/smtpd[2166]: connect from unknown[191.211.100.228]
Oct  9 05:48:26 mx postfix/smtpd[2162]: connect from unknown[103.129.202.216]
Oct  9 05:48:30 mx postfix/smtpd[2166]: warning: unknown[191.211.100.228]: SASL LOGIN authentication failed: UGFzc3dvcmQ6
....

or print only IPs:

# topip -i /var/log/mail.log
191.211.100.228
103.129.202.216
191.211.100.228
