is Identifying Google Domain difficult or I am the only one finding it difficult?

[aashish98]

Hello All,
Recently I was doing some research on finding Domains that google owns, so that i can list them all in one category.
and i can came across this domain: blog.google.

This is one of the Google Domain. it was hard to digest.
it is not blog.google.com [Like a Sub Domain of Google]
but it is a google domain because even if you go to blog.google.com it will redirect you to www.blog.google
have a look at the screenshot below.

both blog.google & www.blog.google have the same certificate.

that qualifies blog.google as one of the Google Domains.

later i also got domains.google.com

Since you can buy domains similar to one that already exists. so then i opened it's certificate but what i saw

[aashish98]

This is also a Google Domain
domains.google Certificate:

image.png (10.14 KiB) Viewed 1487 times

In the SAN List I got a site name:

Over here you can see i went to Site: https:// xn--9kr7l.com
but the domain shown on the browser is https://古博.com/

Both are same
if i need it for one of my service which one should i allow on my firewall
