Hello, thank you for your time.
1. This public IP is now linked with me and my mining farm (through a picture), I've a computer engineer working that is saying me exactly the same as you, but im worried because i dont know if this information can be used to get my exact location, i mean, if i get this IP i cant do shit, but i supose that there are some people over there that maybe can do something.
2. Im asking this for the posibilites of localizate an unused IP.
Like @Lindworm said. You've reveiled your public IP many times before. Basically everytime you've submitted a share. Unless your farm is not behind a capable firewall there's nothing to fear and your situation did not change at all.
