# DigStory: DNS and WHOIS history for every name

> DigStory keeps the history of DNS records, WHOIS data and technologies for domains across the internet, so you can see what changed and when.

## What DigStory does

### DNS history

Every A, CNAME, NS, MX, TXT and DMARC record seen for a name, with when it appeared and when it changed.

### WHOIS history

Registrar, dates, statuses and name servers over time, with every change and the original record text.

### Reverse lookups

Every hostname on an IP address, or behind a CNAME, NS or MX target, with the date each one arrived.

### Technology detection

See which DNS and email providers, CDNs, hosting networks and SaaS services a domain uses, and when that changed.

### Newly observed domains

Domains as they first appear, as a live feed you can browse or pull through the API.

### Watching and webhooks

Watch the domains you care about. Each DNS, WHOIS, availability or technology change becomes an event, signed and delivered to your endpoint.

### JSON API

Everything the pages show, through an authenticated API with quotas and paging for large result sets.

### CSV exports

Reverse lookups and technology reports as CSV, ready the moment you ask.

## How it works

1. **Look up**: A domain or an IP address: its current records and its full history.
2. **Follow**: Watch domains and get every change as an event or a webhook.
3. **Integrate**: Pull the same data into your own tools through the API and CSV exports.

## Frequently asked questions

### What is DigStory?

A history of the public DNS records, WHOIS registration data and technologies behind domains. Look up any domain or IP address to see what it looks like now and everything that changed before.

### How far back does the history go?

To the first time DigStory saw a domain. From then on every change is kept, including for domains that later stop resolving or expire.

### How current is the data?

Domains are rechecked continuously, and changes show up in the history, your watched domains and your webhooks as soon as they are seen.

### Can I get alerts when a domain changes?

Yes. Watch a domain and every DNS, WHOIS, availability or technology change becomes an event. Set a webhook for your team to receive them as signed deliveries.

### Is there an API?

Yes. Everything the pages show is available as JSON with an API key. Each key has a daily request quota, and large lists come in pages.

### Can I export data?

Yes. On paid plans, reverse lookups and technology reports download as CSV, on the web or through the API.

### Is the free plan really free?

Yes. Sign in with your email, no card needed, and keep the free plan as long as you like.

### How do I sign in?
