# DigStory

> The history of DNS records, WHOIS data and the technologies behind domains, with every change kept.

Look up a domain or IP address to see its current records and everything that changed before. Public pages show a sample of each list; signed-in teams on paid plans get complete results, a JSON API and CSV exports.
