DNSSEC available in the domain “”

12 of April, 2016

Since April 4th, the domain “” is being supported by DNSSEC (Domain Name System Security Extensions).

This change allows a step further towards an improvement in access security to computer services hosted in IST.

This new feature will allow the publication of various types of DNS records with public information, such as public key SSH/SSL services or other sensitive security information, with the guarantee that the client is able to use the DNSSEC verification mechanisms to ensure that these consulted computer records, have not been tampered with while halfway between the IST network and the user’s computer (i.e. Man-In-The-Middle or MITM).
