Exclude one IP from historic data (afterwards)


I’d like to see how many people have visited my site, excluding one IP. I have excluded the IP for future trackings but I need to know how many total visitors I had without the particular IP. Do you know how to do that? I do not need to exclude the IP in the database, it would be enough to know how many visitors have been tracked from that IP ( it’s a company network, so there should be several visitors).

Thanks for helping me and taking the time to answer
