DNSSEC service went throught a rapid development in recent years. First domain with DNS signing was swedish domain in 2005. CZ domain supports DNSSEC since 2009 and domain EU since fall 2010. In 2010 was also signed a root zone (highestí) by ICANN organization and many domains is about to begin to support DNSSEC.
Main goal of a DNSSEC service is to prevent the attacker to forward adress of target server to own server and to be able to show a fake web pages of some bank, eshop, etc.
