What is DNS history?

DNS (Domain Name System) translates domain names into IP addresses. Every time a domain switches hosting or email provider, the DNS records change. DNS history is a log of those changes: which IP addresses and servers a domain pointed to, and when.

This data comes from passive DNS sensors that watch real DNS traffic and record what they see. Unlike WHOIS lookups, passive DNS captures changes as they happen. So you get a full timeline of where a domain has been hosted, going back years.

Why check DNS history before buying a domain?

  • Detect ownership changes - A domain that jumped between IPs several times in a few months probably changed hands often. That's a red flag when you're buying expired domains.
  • Spot suspicious hosting - If a domain sat on known spam or malware servers, that history sticks. It can tank its reputation and any SEO value you're hoping to get.
  • Confirm domain age - DNS records show when a domain first went live. It's a good cross-check against WHOIS and Wayback data.
  • See the current setup - Find out the email provider (MX), nameservers (NS), and CDN in one place, without digging through multiple tools.

What DNS record types mean

A / AAAA - Points the domain to an IPv4 (A) or IPv6 (AAAA) address. This is the server where the website actually lives.

MX - Mail Exchange. These tell you which servers handle email for the domain. The number before the server name is priority: lower means preferred.

NS - Nameservers. They tell you who manages the domain's DNS (Cloudflare, Route 53, Google DNS, etc.).

CNAME - Canonical Name. An alias that points one domain to another, instead of pointing directly to an IP.

TXT - Text records. Used for domain verification (Google Search Console, SPF, DKIM) and other metadata.

SOA - Start of Authority. Contains the primary nameserver and admin contact for the DNS zone.
