What top-level domains does youtube have?

Question

I am trying to identify youtube link (generally), and I wonder what top-level domains is youtube using?

So far I know about:

• .com (youtube.com)
• .be (youtu.be)

Are there any others?

PS: for those looking for checking youtube/vimeo video particulary I would recommend to check how to check the valid Youtube url using jquery ...

Answer 1

At the moment, YouTube videos can be accessed by two kinds of link, either the usual URL generated by the UI itself, as you click from one video to the next:

https://www.youtube.com/watch?v=tRgl-78sDX2

Or through a sharing URL, created within the UI by clicking the "share" button:

https://youtu.be/6DzSAaNQHR8

Regarding the second part of your question, what domains are required for access to YouTube? Unfortunately this is a moving target, as the YouTube changes. At the time of writing (Mar 2015), that list is as follows:

*.youtube.com
*.googlevideo.com
*.ytimg.com

In addition to the core domains above, some ancillary domains are also needed to display the ads, etc on most YouTube pages:

apis.google.com
*.googleusercontent.com
*.gstatic.com

The bulk of the traffic itself comes from *.googlevideo.com. Beginning in late 2014, YouTube started progressively enabling SSL on the youtube.com and googlevideo.com domains. You'll need to be aware of this if you're using this information on a filtering or caching device.

Also note this was tested through a browser; native clients (iOS, Android, etc) may operate differently.

Answer 2

I have discovered these Youtube domains so far:

youtube.com // https://www.youtube.com/watch?v=dfGZ8NyGFS8
youtu.be // https://youtu.be/dfGZ8NyGFS8
youtube-nocookie.com // https://www.youtube-nocookie.com/embed/dfGZ8NyGFS8

also youtube.com has a mobile version on subdomain:

m.youtube.com // https://m.youtube.com/watch?v=dfGZ8NyGFS8

I use this list for PHP function parse_url. You may find this question usefull too.
