#1

Most of the time blogs on blogspot.com does not open, and 1.1.1.3 returns an ip range that is different from ip range returned by 1.1.1.1 or 8.8.8.8

What exactly is the issue? The site loads fine on that address.

The difference between Google and Cloudflare can easily be explained with ECS, the difference between .1 and .3 is more surprising and actually does not appear in my case, however that still is a Google address and the site loads fine.

#3

Sometimes it opens and sometimes not. When it returns ip that starts with 172, it does not open, and when the returned ip starts with 216 it opens.

#4

As I said, it does open on that address and that address is a Google address. You might want to contact Google in this case.

#5

If you have difficulties with that address, this might be an issue between your ISP and Google

Even Google returns that address
