IP (Internet Protocol)

Internet Protocol (IP) refers to the set of rules governing the format of data packets sent across the internet, and by extension, the unique numerical address (IP address) assigned to each device or server on a network. IPv4 addresses are 32-bit (e.g., 192.168.1.1) while IPv6 uses 128-bit addresses to accommodate the growing number of internet-connected devices.

IP addresses are relevant to SEO in contexts such as identifying the geographic location of a web server (which can influence local search results), diagnosing server-level issues in log files, and checking whether a site's IP is flagged as a spam source. Tools like MXToolbox and WHM check IP reputation.
