In order to prevent the state table from filling up, sessions will time out if no traffic has passed for a certain period. Send the request and check your email after, please. As far as public IP is concerned, there is a tool (https://dnschecker.org/ip-location.php), that not only locates the IP, by getting information from four geolocation databases but also displays the location on Google maps also. Later, websites included the stateful model, which delivered pages with information unique to each user. These stale connections are removed from the state table.

To be stateful is to essentially rely on these moments in time.

e.g. This cumulative data is evaluated so that filtering decisions would not only be based on administrator-defined rules, but also on context that has been built by previous connections as well as previous packets belonging to the same connection. (Although you can still restrict the rules based on port, protocol, destination IP, source IP, etc.

the logical port assigned to the service being used). Stateless firewall lock after network traffic and limit packet based on sorce and destination addresses.
