How We Tell When a Taken Domain Is Actually for Sale

Basics

You find the perfect name, you check it, and it's taken. Most tools stop there.

But a lot of taken domains aren't being used for anything. They're sitting on a marketplace with a price tag, or on a parking page full of ads, waiting for someone to make an offer. "Taken" and "for sale" can be the same name.

DNSLister now tells you when that's the case.

What you'll see

Next to a Taken result, you may now see one of two badges:

  • Listed at Afternic (or Dan, HugeDomains, Atom, BrandBucket...). The domain is set up on a marketplace that sells domains. It very likely has a price, or at least accepts offers.
  • Parked at Sedo (or Bodis, ParkingCrew, Above...). The domain points at a parking service. Parked names are often for sale too, but it's weaker evidence: some owners park a name just for the ad income.

The badges show up in Quick Lookup, in your search results and in your Favorites.

How it works

Every domain has nameservers: the servers that answer "where does this name live?" When an owner lists a name on most marketplaces, they point its nameservers at that marketplace, so the marketplace can show a "this domain is for sale" page.

So when a name is taken, we look up its nameservers. If they end in, say, afternic.com, the name is listed at Afternic. If they end in sedoparking.com, it's parked at Sedo. It's one quick DNS question per name, and nothing gets sent to the owner.

Quick Lookup checks live, while you wait. For your Favorites and recent searches, we re-check in the background about once a week, so a name that goes on sale next month gets its badge without you doing anything.

What it can't see (yet)

This method has honest blind spots:

  1. Listings that don't change nameservers. Many marketplaces let an owner list a name with a "landing page" link or a simple forwarding setup instead. The nameservers stay at the registrar, so we see nothing.
  2. "For sale" signs on ordinary websites. Plenty of owners just put "this domain is for sale, email me" on a one-page site. Reading those pages is our next step.
  3. Marketplaces we haven't mapped. We started with the big ones. There are dozens of smaller marketplaces, regional ones and broker services.
  4. No badge doesn't mean not for sale. It means we didn't find a sign. Almost any domain has a price if you ask the right owner.

Help us fill the gaps

This is where you come in. If you buy, sell or broker domains:

  • Which marketplace or parking service are we missing? If you know its nameservers (for example ns1.somemarket.com), even better.
  • Would you use a "show only names that are for sale" filter on search results?
  • What would make a badge more useful? A link to the listing? A price, when the marketplace shows one?

Tell us here. The subject line is already filled in. Every reply gets read, and new marketplaces go straight into the list. No code release needed.

Want to see it in action? Run a search on a short, popular word. Plenty of the taken results will turn out to be listed somewhere.
