Searching for explanations for last month’s high-profile hack, a ICANN spokesperson said that the site hijacking of several of its domains was due to a security leak at the registrar that manages those sites – identified as Register.com.

Domain registrar and web hosting provider Network Solutions announced on Friday it is supporting ICANN’s stipulation to applying the non-refundable 20 cent per-transaction ICANN fee to domain names deleted during the Add Grace Period.

The .pro domain, the exclusive top-level domain extension associated with certified professionals, will be loosening its restrictions, according to an announcement from the registry’s operator.
