A domain name portfolio consists of all domain names owned by an individual or corporation.
There are especially two kinds of domain portfolios, domain portfolios owned by organizations and domainers’ portfolios.
While SMBs have commonly a few domain names, international companies may have hundreds or thousands of domains registered in many countries. Some are used for a real web presence, but the majority is often registered for brand safety and protection purposes.
Domainers have often thousands of domains for selling or domain parking. Some domain parking specialists have been said to have more than one hundred thousand domains.
With hundreds or thousands of domain names, domain portfolio management can be an issue and require dedicated tools and services.
