Yearly Renewals and a Name Server Change

GEThttps://api.deepinfo.com/v1/analyze/whois-history

The WHOIS history of example.com: 12 versions, a renewal every August and a move to Cloudflare name servers.

Param: domain
Value: example.com

Asks for the WHOIS history of example.com, a domain reserved by IANA.

The API returns 12 versions (the first 10 are shown), one or more per year: the expiry date moves one year ahead each August. The registrar stays reserved-internet assigned numbers authority. The name servers change between the October 2025 and August 2026 versions, from a.iana-servers.net and b.iana-servers.net to elliott.ns.cloudflare.com and hera.ns.cloudflare.com.
