Most Internet domain name disputes are in essence a fight over the right to use the same domain. For example, if both Bighorn Software and Bighorn Travel develop Web sites to advertise and sell their products, both will probably want to use the domain name “bighorn.com.”

Under trademark law, both could legally use the “Bighorn” trademark because consumers would not likely confuse Bighorn computer software with Bighorn travel services. But there can be only one “bighorn.com” domain name, and the first to request it will get it.
