When it comes to new gtld’s As of Dec. 31, 2017, total new gTLD (ngTLD) domain name registrations were approximately 20.6 million or 6.2 percent of total domain name registrations across all TLDs. This is a decrease of approximately 0.5 million domain name registrations, or 2.4 percent, compared to the third quarter of 2017. ngTLDs decreased by approximately 5.0 million domain name registrations, or 19.5 percent, year over year.
The fourth quarter of 2017 closed with approximately 332.4 million domain name registrations across all top-level domains (TLDs), an increase of approximately 1.7 million domain name registrations, or 0.5 percent from the third quarter of 2017.1,2 Domain name registrations have grown by 3.1 million, or 0.9 percent, year over year.1,2
Total country-code TLD (ccTLD) domain name registrations were approximately 146.1 million, a 1.0 percent increase over the third quarter of 2017, and a 2.4 percent increase year over year.1,2
The .com and .net TLDs had a combined total of approximately 146.4 million domain name registrations in the domain name base3 at the end of the fourth quarter of 2017. This represents a 2.9 percent increase year over year. As of Dec. 31, 2017, the .com domain name base totaled 131.9 million domain name registrations, while the .net domain name base totaled 14.5 million domain name registrations.
New .com and .net domain name registrations totaled 9.0 million during the fourth quarter of 2017 compared to 8.8 million for the fourth quarter in 2016.
Likely a drop in the bucket, if that, when compared to non-IDN registrations, but I wonder how much of the ccTLD growth is accounted for by IDN registration(s), specifically emoji domains?
