What is the domain "nrb.footprintdns.com"??

Hello Everyone

 

From 3/2/2018, when I access my SharePoint site the following certificate site? is displayed.

https://37CFD84CE79EF6104C98E018AE6ABD10.nrb.footprintdns.com

And request me to type account and pw.. Although I entered my PW I cant access my sharepoint site. I want to know why? And how can I access my site.

 

So I want to ask the following questions:

 

1.When I access the above URL Office 365 sign in page is appeared what is the relationship between Microsoft?

 

2.Since today Microsoft is beginning to use the [nrb.footprintdns.com] domain?

 

3. What is the purpose that Microsoft use the [nrb.footprintdns.com]?

 

4. I googled and I found the following site. And I can also search the domain [37CFD84CE79EF6104C98E018AE6ABD10.nrb.footprintdns.com] in there.

https://www.threatcrowd.org/

I really don’t understand why microsoft use the thteats? Site for what purpose DNS?

I did not have this situation previous to 3/2/2018.

 

Can anyone tell me how to resolve this situation..

 I do not have any certificate knowledge so I will very appreciate if anyone can tell me the reason simply.

 

Thanks.

Sorry, but I'm not following you here: when is that Url displayed?

Can someone explain the purpose of *.footprintdns.com domains? To be specific what *.nrb.footprintdns.com does? Something weird about this domain.

I'm also seeing network traffic for this domain and it seems to be loading a 1px .gif image to the page. 

The problem here is that the image takes multiple seconds to be loaded!

Why is there no response from Microsoft on this?

 

This domain is blocked by my adblocker under the category "Spyware filter" though it is clearly owned by Microsoft. 

 

We need an official explanation of what this is doing. Most importantly, we need to understand why this is not listed in the official URL list for Office 365.

 

We also need to know the impact of this domain being blocked which is clearly is being by some security tools.

Fiddler to my sharepoint site displays this: The server (0d255cb7441615dbb825de4d81cddac7.nrb.footprintdns.com) presented a certificate that did not validate, because it was issued to a different host.
