What Is a WHOIS Lookup and How to Use One

Every domain on the internet has a public registration record attached to it — who registered it, when, through which registrar, and when it expires. That record is called WHOIS, and it's one of the oldest and still most useful tools for quickly sizing up an unfamiliar domain.

What a WHOIS Record Actually Contains

A typical record includes the registrar (the company the domain was bought through, like GoDaddy or Namecheap), the creation date, the expiry date, the name servers currently handling its DNS, and — unless privacy protection is enabled — contact details for the registrant, administrative, and technical contacts.

Since 2018, most registrars enable free WHOIS privacy by default, which replaces personal contact details with the registrar's own proxy information. This is normal and doesn't itself indicate anything suspicious.

Why Domain Age Matters

The creation date is often the single most useful field. A domain that was registered three days ago and is already asking for your bank login is a massive red flag — legitimate businesses rarely operate on brand-new domains. Established, reputable sites are almost always years old.

Checking Expiry Before It's a Problem

If you own the domain, WHOIS is also the simplest way to double-check your own expiry date, especially if you're not fully sure auto-renewal is switched on. Domains that lapse can be re-registered by anyone within a short window, sometimes ending up in the hands of squatters.

Name Servers Tell You Who Manages DNS

The name servers listed in a WHOIS record show which company is actually managing that domain's DNS — which can be different from the registrar. This is useful when troubleshooting a migration, or figuring out who to contact when a domain is causing abuse and the registrar alone can't help.

Run a Lookup

Nexora Shield's WHOIS Lookup tool pulls all of this in one request — registrar, dates, name servers — so you don't need to dig through a registrar's own portal.
