How to Find Parked Domains in a List of Company Websites

To find parked domains in a list of company websites, check each domain's nameservers and home page for parking signals. The bulk parked domain detector does it for up to 100 domains (500 after a free Google sign-in) and labels each row Looks for sale, Looks parked or No parking signal, with the signal that matched.

A domain that is parked or for sale has usually stopped trading under that name, so its email addresses are a bounce risk.

The by-hand way

Open the domain and look at the nameservers. Visit the home page: a generic page with ads, "this domain is for sale" or a "buy this domain" button is the obvious case. Then run dig NS example.com +short. Nameservers that belong to a parking or sales service point the same way. A redirect to a domain marketplace is a third sign.

That is fine for ten domains. For a list it is slow, and the page alone misses domains that redirect or show a blank page.

Step 1: paste the domains

Paste one domain or a list, one per line. Emails and URLs work too. You can also upload a CSV. No account is needed for up to 100 a run; sign in with Google for up to 500.

Step 2: run the check

Each domain's nameservers are looked up and its home page is requested once, five at a time. The home page is read over HTTPS first, then HTTP.

Step 3: read the result as a signal

Result	What it means	What to do
Looks for sale	A signal says the domain is being offered for sale	Likely not the company's live site
Looks parked	Parking nameservers, a parking redirect, parking files or parked wording	Check the company by name
No parking signal	None of the four signals matched	Not proof the site is real

The four parking signals

• Parking nameservers. The domain's nameservers belong to a parking service such as Sedo or Bodis.
• Marketplace redirect. The site redirects to a domain marketplace such as Dan or Afternic.
• Parking assets. The page loads files from a parking service.
• Page wording. The page says the domain is parked or for sale.

Each row shows which one matched, and the CSV carries the evidence. Nameservers are part of how DNS delegates a domain; see RFC 1034.

Using it on a lead list

Take flagged rows off the send list, or look the company up by name: it may have moved to a new domain. Parking is one of several ways a company disappears from the web. To combine it with the site's status and its mail records in one verdict, see how to remove dead companies from a lead list. For emails sent to parked domains specifically, read parked domain emails.

What this check cannot do

• Signals come from nameservers, redirects and page text, not certainties.
• A parking page built on a service the tool does not list shows no signal.
• Only the home page is read.
• The limit is 100 domains a run without an account and 500 signed in.

If the company is still alive, check the contact emails

A site that answers does not mean a given mailbox exists. Once you know which companies are still around, check the addresses on your list on the verify page: the first 100 email checks are free with a Google sign-in, no card. Each comes back valid, risky or invalid with a reason, and nothing is sent to anyone on the list. To confirm every site still answers first, run the list through the bulk website status checker. For larger or recurring lists, see bulk email verification, list cleaning and pricing.
