Check Ip is ISP or Company using php

Question

I'm using php whois lookup to fetch details of an ip and I am very much successful in it. But I need to detect whether the ip belongs to an individual or an organization.

For example if I browse my tracking website from home it is my individual ip but if I browse it from my office (my company) it is an organization. The fact is I want to track all "company visitors" visiting my site. I'm not interested in individuals. So I need a way to differentiate between the two. Since if I go for whoislookup of individual ip, it returns the ISP as Organization and for generic organization ip it returns the organization name. So basically I need to detect whether the ip is ISP or Generic Organization.
