Question

Is it ever possible that there will be duplicate IP addresses for two devices at the same time accessing my website? this is how I get the IP address

$_SERVER['REMOTE_ADDR']
Was it helpful?

Solution

Yes. If they are behind a firewall performing NAT, all of the connections could be coming from multiple clients, but will appear to be originating from the same IP Address.
