TLD Zone File Statistics September 2021 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 are not listed in zone files and thus not taken into account.
