IP Reputation
The concept of reputation is used commonly in our daily lives. It is often used as a metric to evaluate an entity, be it a place, a person, a group or an organization, a school or a company, and so on. The reputation associated with a particular entity is made and/or adjusted based on past and ongoing experiences, whether good or bad. A good reputation will open doors to incredible opportunities, whereas a bad reputation will result in closed doors. IP reputation follows the same concept. The object with which we associate the reputation is an IP address.
