VeriSign has promised to deploy DNSSEC across all of its top-level domains within two years. According to reports, \'.com\' will most likely be the last Top-Level Domain (TLD) to adopt DNSSEC due to the size of the zone. However it is anticipated that full implementation of DNSSEC will be complete across all TLDs in about 24 months.
DNSSEC has been deployed on top-level domains operated by Sweden, Puerto Rico, Bulgaria, Brazil and the Czech Republic. Two larger domains—.org operated by the Public Interest Registry and .gov operated by the U.S. government—are deploying DNSSEC this year.
