Thanks for your comment and for highlighting this.

As a summary for others: Telnic (and Telnames) allowed people to store contact data in the DNS of their .tel domain name.

> Sounds similar to Telnic

Telnic used NAPTR records and was only available on .tel domains, NUM uses TXT and can be used on any domain name, by publishing a "_num" zone.

Telnic was also "just" for contact data. What we're trying to do with NUM is make it possible to publish any kind of data. Contact data as just one "module".

The other key difference here as far as I understand, is that Telnic required you to register .tel domains, you couldn't bring your own domain and store contact information against that.
