ICANN have released a package which fixes problems caused due to recently added domain addresses. Web site designers and applications will be able to use the toolkit to fix these problems. The problem refers to websites rejecting newer TLDs created since 2001 (e.g. .mobi or .info). The toolkit checks validity of e-mail addresses and websites against a root-zone (a master list where Web sites with certain TLDs can be looked up). The look-up translates URL of Web sites from words into numerical addresses allowing the page to be called up by browsers.

"It wasn’t so long ago that .COM and .NET – the last bit of a Domain Name – were largely the only options for Internet users. Now, in addition to more than 240 country code TLDs, there are also .AERO, .BIZ, .CAT, .COOP, .INFO, .JOBS, .MOBI, .MUSEUM, .NAME, .PRO, .TEL, .TRAVEL. Another, .ASIA, is expected to be added shortly, this choice is a good thing but some users of these new domains have had problems using e-commerce and other websites that don’t recognise some new top-level domains. That means email and website addresses from some of these TLDs get rejected as invalid. The toolkit helps fix that problem for Internet users by making sure software developers and application providers have the most up-to-date information about the Internet’s Domain Name system (DNS)" said Kim Davies, Technical Liaison for the Internet Assigned Numbers Authority (IANA), who helped designing the toolkit. IANA is a function carried out by ICANN.

The ICANN toolkit saves developers and site operators money and time via the task of re-programming systems every time a new top-level domain is created. The code can be easily inserted in existing programs or applications, and will check validity of an email address or URL against DNS data. Once installed, there is no need for additional updates. Changes will be automatically noted and the program is now in its third Beta version. It will be improved based on user feedback. "In the long run, this will ensure that the addition of new TLDs will be as smooth as possible, and make sure all Internet users get full usability of their domain,"said Davies.
