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

The NS history of deepinfo.com: HostGator name servers from 2018 to September 2019, Cloudflare name servers since January 2021.

Param: domain type
Value: deepinfo.com NS

Asks for the NS history of deepinfo.com (type=NS).

The history shows a DNS hosting move. ns2309.hostgator.com and ns2310.hostgator.com were seen eight times each, from January 1, 2018 to September 27, 2019, and ns8057.hostgator.com and ns8058.hostgator.com once, on December 28, 2018. may.ns.cloudflare.com and simon.ns.cloudflare.com were first seen on January 6, 2021 and last on September 18, 2026; the page shows their 10 newest observations.

Each of the two Cloudflare name servers appears a second time, with two or three observations from October 29, 2021 to January 1, 2022. Those dates fall inside the period of its first entry: it is the same name server, listed twice.
