Can IP change during session?

Question

Can IP change during session?

What about different engines (PHP, Django, Ruby, etc) ?

PS: I don\'t quite understand what is \'dynamic ip\' and how they are h

Answer 1

1) Yes, an IP address can change during a session.

3) No, I can't think of any security benefit of "tracking IP changes".

2) A "dynamic IP address" is simply the opposite of a "static IP address:

a) With dynamic IP's ("DHCP"), the network assigns the address to a host (typically, when you boot up).

b) With static IP's, you configure the host with a fixed, unchanging address.

c) Dynamic IPs are the norm. They're easier to administer, they relieve the end user of having to do any network configuration, and they mitigate the risks of conflicting network addresses.

Here is a good link that might make the distinction between "static" and "dynamic" addressing clearer:
