THE TECHNOLOGY

The .tel is the first TLD to harness NAPTR, TXT and LOC records within the DNS and thereby power a compelling solution for contact management that enables both individuals and businesses to store data directly within the DNS.

NAPTR records are a recent and more flexible DNS resource than the conventional Address records used thus far. The stability and robustness of NAPTR records have been proven in a protocol called ENUM, a mechanism for translating telephone numbers into domain names. However, unlike ENUM, the .tel is not encumbered by the regulatory environment found in the conventional telephony world. Additionally, unlike ENUM, .tel is not linked to a single phone number and is therefore portable.

NAPTR records are at the core of what makes the .tel domain powerful and meaningful to individuals and businesses. These NAPTR records will allow for the publication and management of contact information in a way never before possible, including phone numbers (both mobile and fixed line), email addresses, fax numbers, VoIP service identities such as Skype, AIM, MSN (and allow users to distinguish between them), links to webpages, maps and blogs.

These NAPTR records can also point to other NAPTR records, allowing for navigation through a tree of contact information based on geography, department or any other segmentation. They allow for unlimited updating of dynamically changing content and offer immediate global access to all newly updated information. They can be encrypted to protect confidential data and all data returned within the NAPTR records is clickable, enabling a click-to-communicate feature, which makes communication using the .tel as easy as possible for the users.

In addition to storing NAPTR records, the .tel uses Text records or TXT records stored directly within the DNS. These TXT records allow for the publication of text based information such as names, titles, mailing addresses, and keywords that will help users search for and find the right person or business they wish to contact. These keywords may be easily indexed and searched, enabling the creation of a DNS-based global white and yellowpages directory service.

Lastly, the .tel uses Location records or LOC records to publish geo-location information. This allows businesses and individuals to indicate their precise location. The benefits of publishing live LOC records will increase as more advanced location-based services emerge over the coming years.
