Sorry but I has a problem that I don’t know why.
In our forum, registration IP Address is duplicated for so many users. It seems so strange.
And I can’t understand.
Please help me to make it more clear. It’s normal logic or a bug or anything else ?

Registration IP Address Issue on Microsoft Azure
The discussion revolves around an issue with duplicated registration IP addresses for many users on a Discourse forum hosted on Microsoft Azure. Chi_Duc initially reported the problem, and itsbhanusharma suggested that it could be due to the way Microsoft routes traffic to the server. However, Chi_Duc clarified that the IP address in question is not the forum’s public IP but rather an IP from Dublin, Ireland.
Ivan_Rapekas suggested that incorrect proxy settings might be the cause, and JagWaugh pointed out that the IP address is registered to Microsoft, potentially indicating that Microsoft employees are accessing the forum. However, Chi_Duc believes this is unlikely due to the large number of affected users.
Chi_Duc revealed that the forum uses single sign-on with a website, and user registrations are handled through an API. Both the website and forum are hosted on Microsoft Azure, which might be the root cause of the issue. However, the IP address logged is not the website’s server IP address, leaving the exact cause still unknown.
Are You hosting on Microsoft azure?
Yes. And can you tell me more ?
It could be the way Microsoft routes traffic to your server. If they’re hosting you on a local IP then it is possible that discourse sees all requests originating from your server’s public gateway IP.
You’d have to configure your server to be assigned a public IP directly in order to resolve this or contact Microsoft for help.
Sorry but the ip above is not our forum public’s ip @@
It’s ip of Dublin, Leinster, IreLand like in this image.
We already have public ip on internet.
So may be reason is something else?
Is it all users or some users?
Hi Pfaffman,
3410 is just some users. Total of users is ~ 20.000
Is it possible that your forum is of particular interest to Microsoft employees?
Hi JagWaugh
Why do you say that 
I don’t understand @@
That ip is registered to Microsoft. If they’re employees then they might be accessing the internet from that ip while they’re at work.
Hi @Chi_Duc, I am not sure about Azure servers, but usually the server’s IP as a user’s IP is shown in case on incorrect proxy settings. I mean Nginx settings. Try to add the lines from my post into your app.yml and rebuild. Anyway, this will break nothing, and you always can revert these changes any time.
I suppose your server may have dynamic IP, therefore some users have the same IP.
Thanks @JagWaugh
The number is so big, so I don’t think it relates to Microsoft employees
Thanks @Ivan_Rapekas
Actually, we have one website and one forum. They are single sign on.
So user can’t register directly on forum. They register on website, then our website sever sends request api to register them on forum.
And both website and forum are being hosted on Microsoft Azure.
May be this is the root of my problem.
But the IP address was logged is not IP address of my website’s server.
So I still don’t know how was this IP address logged @@
