Hello or rather good evening,
Having been absent from the site for a while (shame on me), and in almost total confusion.. I would like to call upon your knowledge!
My question has undoubtedly been raised before, but I have little information on the web, and no one in my circle is likely to provide me with a clear answer.. in the context of my engineering studies, I must ask myself this question.
So, I have read several times that it is not possible to keep an IP address after moving. Some people’s statements seem to justify that the link to the DSLAM varies after a move, which seemed logical to me until now! I have also read that the distribution of IPs by some operators is done geographically. So far, so good. Upon reflection, I even think that changing IPs after changing address and consequently changing DSLAM is inevitable, even for a fixed line.
However, and this is where it gets complicated.. are there exceptional cases that some of you may have encountered where this logic does not hold? Let's take the case of a server hosted at home not managed by the DNS (we're taking the extreme case here), so no name resolution, only accessible via the IP, how does that work? Or the case of hosting with a wholesaler-type host, does changing an IP affect the hosting? And finally, the last case (let's be crazy!) in the context of surveillance or other matters, can the state force a client to keep their IP after moving?
Sorry for my tricky questions! And thank you again in advance to those who can guide me or even open the doors of knowledge! :)
In this waiting, thank you!

Following up...
For the psycho-tasking, if you don't have a DNS name and a changing IP, if the NSA or others are interested in your case, they will find you, unless you move often; you just have to wait behind your ports for them to open... -
Hello,
Quick answer, if you don't have a dynamic IP, which changes, the problem does occur in case of moving, ISPs (Internet Service Providers) all provide a service allocating a domain name that allows you to be recognized on the web wherever you go, with Orange it's called DynDNS. -
Hi,
There are moves and moves.
First of all, if you change your ISP, it's dead; IP addresses are assigned to ISPs and hosting providers only.
Furthermore, the IP address has no geographical meaning and the PPP protocol in most cases can lead to a very distant BAS.
Most ISPs, except perhaps Free, are capable of providing a fixed IP completely independent of your postal address.
--
and ... There you go!-
First of all, thank you for your responses and sorry for the delay!
As for intelligence agencies, I think they can rely on criteria other than just the connection point.
I had heard about it, but it doesn't tell us whether or not they are capable of reassigning the same IP in another geographical area, after a request from the client or not.
