How many top-level domains are there? — April 23, 2018

How many top-level domains are there?

The actual number changes occasionally because new TLDs (top-level domains, also known as domain extensions) get launched on the internet from time to time. The current number of top-level domains can be found on this web page:

What are the most valuable top level domains? If the winning amount of these auctions are an indicator of value, these are the top-level domains that the applicants believe to have the highest valuations:

Auction results are listed at ICANN… Only contention sets that resolved through Auction are included. That page will be periodically updated within seven (7) days after an Auction or update in status. Information about the Auction process, Auction proceeds or additional contention set status’ can be found on the Auctions page, Auction proceeds page or Contention Set Status page, respectively.

I confess that I don’t quite get how all of these top-level domains are worth millions or multiple hundreds of thousands. The ones that do make sense to me as having very high value are: .APP, .REALTY and .BUY. The others could sure have the potential of becoming valuable to the degree that the investors make their money back or get a profit, but that’ll take quite a bit of work.

Google Registry’s .APP domains are available in May 2018 — June 26, 2015

Google Registry’s .APP domains are available in May 2018

// (3/3/18) Google announced important launch dates for .APP domain name registrations—

Here are the important dates to be aware of in 2018:

Mar 29 – May 1: Trademark holders can register .app domains (known as the “Sunrise” period).

May 1 – May 8: Anyone can register available .app domains for an extra fee (known as the “Early Access” period).

May 8 and on: Anyone can register available .app domains (known as “General Availability”). //

// Google announced on 12/14/17— “We are currently finalizing plans to launch .app and .dev as open top-level domains in the first half of 2018. If you’re an ICANN-accredited domain registrar, please send a request for more information.” //

// [chatter @ stackoverflow January 2017] “Little update, almost two years later and still no news. Google seem to keep the .app to themselves, to protect their Play Store.” //

// [update April 2016] Announcement at = “We’re currently working on plans for .APP… If you’d like to know when and where you can purchase your own .APP name, please check back here for updates or with your chosen Registrar.” //

Perhaps the most popular domain extension on the Internet will be domains that end in .APP, so much so that Google paid $25 million for the .app domain — that is the most any company has paid in one of ICANN’s auctions so far. Wouldn’t you want a domain that ends in .APP, especially for your app?


When this becomes official is marked by an event called delegation, the occasion when the Internet will recognize .APP domain names. According to the official ICANN website, the status of the .APP top level domain is:

Application Status: Transition to Delegation

Application Status: Delegated

And the official Delegation Record for .APP will be posted at [delegated June 29, 2015]

Then the website will be up and running! And that will be the only .APP domain name allowed to be active for the 90 days after delegation, or about 3 months. Stay tuned for on-going developments…

The next announcement will be when the Sunrise Period starts for .APP and that will be posted at the master calendar and a web page will be created at

[update 10/16] this chart gives you perspective with the most expensive top-level domains, those that were runner ups compared to .APP— [update January 2016] and .SHOP was auctioned for $41.5M— [update August 2016] .WEB was auctioned for $135M, and .BLOG was auctioned for $19M
