TLD Zone File Statistics December 2018 Reports
StatDNS publishes monthly TLD zone files reports. For each TLD, we compute statistics about:
- Glue records: number of IPv4 and IPv6 glue records present in the zone
- Name servers: number of NS records and unique name servers present in the zone
- DNSSEC: number of DS records and signed domains present in the zone
- Domain names: number of IDN domains (internationalized domain name), and global domain count
Domains not configured with name servers at the TLD registry are not listed in zone files and thus not taken into account.
