![]() The PHP runtime maintains a set of superglobal arrays. Since the IP logging is done on the server side, it is possible to write and augment the PHP code to perform IP logging in addition to executing the main business logic. PHP is a popular choice for building the serverside logic for web applications. Globally the IP addresses are managed by the Internet Assigned Numbers Authority (IANA), which maintains a regional pool of IP addresses for every continent or geographical area. In the case of corporates, leased lines or dedicated network infrastructure are configured with a public IP address assigned to the network gateway. For example, for retail customers accessing the Internet from a broadband connection, the router is assigned a public IP address every time it is switched on and connected. Public addresses are the ones assigned by an Internet Service Provider (ISP) to various customers for communication over the Internet. These addresses are not known on the Internet. ![]() Private addresses are used to communicate between computers in a local Intranet. IP addresses can also be categorized as private and public addresses. In the case of IP addresses, these parts define a network and host addresses and are represented in an IPv4 or IPv6 format.įor more details on the IP address format, refer to the specific RFC (Request for Comments) specification document that defines the addressing mechanism and protocols for all applications to communicate over the Internet. The addressing mechanism follows a similar format as telephone numbers, where certain digits represent parts of the address containing country codes, area codes, and local phone numbers. Each IP log is a record of an IP address that represents a computer's unique address connected to the Internet. The IP address is the key information captured as part of IP logging.

This post covers a detailed guide on the various aspects and uses cases of IP logging, along with popular tools and advanced techniques. Overall, IP logging also has regulatory importance in keeping up with the cyber security and data protection laws prevailing in various countries and continents worldwide. On the other hand, it helps to weed out malicious users. On the one hand, it helps customize the user experience for portal visitors. IP logging assumes a lot of importance in web applications.
