Web addresses ending in extensions such as .accountant or .pizza will soon join the online world where .com has long been the sought-after destination. Yet the majority of small and midsize businesses (SMBs) still have no idea the new real estate is about to hit the market.

The Internet Corporation for Assigned Numbers and Names (ICANN) received nearly 2,000 applications when it opened the doors for new generic top-level domains (gTLDs) last year. A gTLD is the string of characters "to the right of the dot" in Internet domain names, such as .com or .org.

Mega-brands like Apple and Google were among the large enterprises that bid to own and govern extensions like .apple and .google. (Google, for one, applied for more than 100 gTLDs.) Domain marketplaces like Donuts.co, on the other hand, focused on the "generic" in gTLD. Donuts.co applied for extensions like .architect and .restaurant with plans to sell the corresponding URLs at retail, as the likes of GoDaddy or 1&1 do with the 22 widely available gTLDs. The new extensions are set to start going on sale later this year.

Nearly two-thirds of small businesses, though, have no idea the new extensions are coming, according to a recent survey by domain vendor Sedo. The poll included roughly 600 small business owners and managers, and 94% of them said they currently had no plans to purchase a new gTLD for their company.

Those SMBs stand to get squeezed out of the next Internet land grab. While a .com URL might remain the desirable address for the foreseeable future, the massive increase in potential domain names could create a variety of brand and trademark infringement headaches for businesses.

"Because 1,000 new gTLDs will be released annually, trademark owners face new challenges to their brands as the unscrupulous seek to register their brands to the left of the dot of the new gTLDs," said attorney Jeanne Hamburg of Norris McLaughlin & Marcus in an email to InformationWeek. Hamburg chairs the firm's Internet law group. "For example, generalmotors.manufacturing would infringe GM's rights in its brand by including the GM brand to the left of the dot in the new gTLD .manufacturing."

Hamburg advised that brand owners submit their registered trademarks to ICANN's Trademark Clearinghouse, the organization's program for dealing with infringement issues when new gTLDs are made available for sale. Hamburg noted that, for a fee of up to $150, registrants will be notified any time someone buys a URL that potentially infringes on their trademark "to the left of the dot" during the first 60 days the gTLD is available. The clearinghouse opens on March 26; ICANN calls it "the one-stop shop for protecting your brand in the new gTLD era."

Of course, not every company possesses GM's stature. Hamburg said SMBs will have to decide whether it's worth registering with the ICANN clearinghouse based on their past experiences with brand enforcement on the Web. "I do note that trademark infringements need not be willful," she said. "[We] frequently have small business clients who ask us to assist in pressing claims against others who have unwittingly infringed their rights."
