IP address from log files looks dynamic with same visit.

[Volitics]

The log files for my web site have visitor's IP address where the third and fourth columns change for the same visit.

I thought that for a dynamic IP address it was supposed to remain fixed until they disconnected from the Internet - not change or rotate during the visit.

I'm not an expert at reading log files but it looks like the third and fourth columns will change for the log file lines even for just one page.

Are the changing IP addresses caused by a web bot or does the IP address sometimes change during the visit for real visitors?

Thanks.

Yes, the IP address does sometimes change during a visit for real visitors. There's no law that states a proxy server has to use the same IP for two separate transactions even if those transactions are from the same client.
