look, I don’t want to join this discussion, but I will just leave this here.
Doubt that any damage occured to either your PC or router, also it’s your router’s fault for having SSH open.
I am saying the same thing as @Tiger, what can you do with an IP?
WHOIS, and get not-so-accurate info?
Try to login? Probably no, since most routers don’t have SSH/Telnet open.
