I'm having a problem for the very first time since I've owned a VPS with my IP. I have a feeling it is a bad IP as a huge variety of IPs and sources have been trying to access my VPS since 16 June - here's a small sample of what I've been getting from 16 June to date (I took a list of lastb for all of the bad login attempts since I took ownership of the IP). What IPs are the ones that aren't straight IPs like have text in them?
Note that I've also taken a list of the successful login attempts, and they were only my IP. Only the number of my actual logins.
Also note that this is not my post4vps VPS - it is one that I have with HostUS - and the first time that it has ever happened to me with an IP from them - I've had a good few.

If I change port 22 to a different number will that stop these attempts? And what will the consequences be for my WordPress applications if I change the port number?
