Consider using fail2ban, it will grok your logs, and block specific ip addresses based on previous failures.

I live in Taiwan. While I get the most ssh attempts from China, no surprise there, the second most offending
country is the USA.
Rather than doing something which needs updating, I decided to only allow public-key authentication on
ssh connections.
Fun Fact: For the period Jan 31 to Apr 7 there were IPs from 116 unique countries attempting logins via ssh to my
system. I run IPv6 as well and no attempts were made via those addresses.
