Active nameservers

Our sample of 2.3 million domains comprised IDNs in gTLDs (both top and second level), .eu (second level).

There is an overall rate of 51% IDNs with active nameservers.  There are significant variances between individual TLDs.  There are also variances between top and second levels:  26% of top level IDNs have active nameservers, whereas 58% of second level IDNs have active nameservers.  The difference may partly be attributable to the relative newness of the top level IDN gTLDs.  For example, 71% of registrations in the top level .РФ, launched in 2010, have active nameservers.  It may also reflect challenges of universal acceptance or low user awareness of top level IDNs.

The largest second level IDN space in our sample is .com (second level), which has a 58% rate of active nameservers.  In .eu (second level), 75% of registrations have active nameservers.  Of the new gTLDs at the second level, we see that geographical names tend to have above average levels of active nameservers, for example, .Tokyo (77%), .Berlin (82%) and .Nagoya (81%).  At the lower end of the scale are .top (8%) and .wang (9%).

The top level IDNs in our sample also show a wide spectrum of active nameserver levels.  For example, the largest top level IDNs space in the sample, .网址, with more than 350,000 registrations, has only 12% with active nameservers.  The second largest top level IDN, .在线, with 36,000 registrations has 94% with active nameservers.  To some extent, the age of a TLD has an impact on rates of active nameservers.  So, while .在线 was launched in April 2014, .网址 went into general availability from January 2015.  We would expect to see rates of usage settling in the coming year, as the new gTLD spaces begin to move beyond their initial launch phases.
