How are ip addresses distributed via a DHCP server?

Question

DHCP

Hello. I read articles on this topic (the first links in Google, there is too much theory and water), and I could not understand how exactly the client receives ip and whether it can change from request to request. My case: on a third-party site, there is a JS file connection from my service, when loading which I get the IP of the user who made the request. Based on it, I give JS, which builds HTML with a link. And if a user follows this link, can he theoretically have a different IP?

Answer 1

And if he follows this link, can he theoretically have a different IP?

theoretically, anything can happen.
In practice, under certain conditions, the situation described may also occur, but usually this does not happen.

Answer 2

Maybe. From the moment js is loaded to the moment of transition, the client may, for example, reconnect with the provider with a change in the external ip-address.

Answer 3

in Vladivostok, users of one provider at one time even balked due to the fact that the IP address was constantly changing. the users themselves sat behind NAT
