Active name servers by level


A domain name must have active name servers in order to support services such as a website or email. Measuring the rate of active name servers can give a general sense of the rate of active use, and indicate the likelihood that domains in a particular TLD will renew – as active domains are more likely to be renewed than inactive domains.

Our sample of 2.3 million IDNs contains approximately 1.8 million second level IDNs (including .com, .net and .eu) and 500 000 top level IDNs (all of which are part of the ICANN new gTLD programme). We reviewed the rate of active name servers by level of IDN, and found a 62% of active name servers in second level IDN (an increase of 4% compared with 2016), and found a 31% rate of active name servers in top level IDNs (a decrease of 19% compared with 2016).
