This year saw the highest ever number of cybersquatting cases filed, according to the World Intellectual Property Organisation.
According to the body, 2,329 cases were handled last year and included disputes over URLs relevant to the BBC, Arsenal football club, actress Scarlett Johansson and Madrid's 2016 Olympic bid.
The WIPO also said ICANN's plan to allow any web user to buy a top-level domain name could increase the number of cybersquatting cases.
WIPO director-general Francis Gurry told Reuters: "The creation of an unknowable and potentially vast number of new gTLDs (generic top-level domains) raises significant issues for rights holders, as well as internet users generally".
Gurry said the WIPO would work with ICANN to check the proposed suffixes to avoid cybersquatting cases.
Gurry also revealed that trademarks that do not have a meaning such as Sony and Kodak are easier to defend than those based on words or names.
