Technically, all IPs are the same, it's just an address made from numbers.
What happens is that the known cloud providers ( such as AWS, Google, etc ) have their own ranges of IPs that they use for assigning to the VPS that their clients use.
So by knowing a range, you know that every IP within that, comes from a certain cloud infrastructure provider.
In your case, that means they know it's not your house IP, but a server.
Also, you can easily find information from the meta-data that comes with every address.
For example, it's easy to see that arbusers.com leads to 184.108.40.206
and then that leads to some company in Berkshire called "Simply Transit Ltd".
That's where the admin has hosted this forum.
