You mean that all these connections originate from 18.104.22.168?
"iptables -I INPUT -s 22.214.171.124/29 -j DROP" will take care of it.
While you're at it, write an abuse letter to Jonathan Lamptey - he? owns

If you have password-enabled ssh with stock Ciphers, MACs, and Kex'es
enabled, and your only protection is non-standard ssh port - then you
are doing it wrong.
Set these to /etc/ssh/sshd_config, and watch all those script-kiddies
cry as they won't be able to connect to you at all:
And forbid ssh password authentication. They've invented key-based
authentication for cases like yours 15 years ago.
