  1. .tk is a ccTLD that is provided for free to individuals and businesses worldwide (http://www.businesswire.com/news/home/20131216006048/en/Freenom-Closes-3MSeries- Funding#.UxeUGNJDv9s). The zone size for .tk was last estimated by Zooknic in Q4 2014 and this zone size was subsequently used in the Q4 2014 through Q2 2016 DNIBs. In Q3 2016, Zooknic reported a significant decline in the .tk zone and restated the estimated zone size of .tk for each quarter from Q4 2014 through Q3 2016 using a proprietary methodology. As a result, for comparative purposes of this DNIB to the Q2 2016 DNIB, Verisign has applied an updated estimate of the total zone size across all TLDs for Q2 2016 of 325.2 million and an updated estimate of the total ccTLD zone size for Q2 2016 of 140.5 million.
  2. The generic top-level (gTLD) and ccTLD data cited in this brief: (i) includes ccTLD Internationalized Domain Names, (ii) is an estimate as of the time this brief was developed and (iii) is subject to change as more complete data is received.
  3. The domain name base is the active zone plus the number of domain names that are registered but not configured for use in the respective Top-Level Domain zone file plus the number of domain names that are in a client or server hold status.
