The .tel top level domain allows you to create a virtual address book or a virtual business card, storing a variety of contact information online. Why is this so attractive?
.tel domains store your contact information directly in the DNS which can then be universally accessible. This stands in contrast to the typical use of the DNS for other domains, in which the DNS only provides a mapping between domain names and IP addresses. In other words, the .tel domain allows you to store all your contact information online (phone numbers, email contacts, social networks, GPS coordinates and more) without having a hosting account but rather through the innovative technology of using the DNS for storing information.
.tel domains are accessible from the web via any browser, and even through an iPhone, BlackBerry or any other mobile internet device.
The backend management system is very easy to navigate and edit. All in all, one huge advantage of the .tel domain is that you can go online with the least possible effort – just put your contact information and it is online within a couple of minutes.
