Big businesses will shell out for custom Internet domains in the next few years when hundreds of new suffixes become available to supplement .com, .gov, .org and others. Expect domains like .dupont, .exxon-mobil, .amex and .pepsico to flourish.

There’ll be lots of generic domains, too. Look for .realtor, .food, .green, .wine, .nyc, .boston, .music, .hospital and others. They won’t come cheap: The application fee will be $185,000. That will cover legal costs, processing fees, and the work needed to ensure that an applicant is legitimate and technologically capable of running a domain.
