In the context of electronic communications networks, an Address is a unique sequence of characters or numbers that serves to identify a given element, device, or endpoint on a network. Its primary function is to provide routing capabilities—that is, to determine the exact path a data packet should take from its source to its destination.
Conceptually, an Address is a mechanism for location and direction. In the Internet environment, the most well-known examples of addresses are the IP address (e.g., IPv4 or IPv6), which identifies a device’s network interface, and the MAC address, which is a physical address at the hardware level. It is important to distinguish these network addresses from the Internet address (URL), which is a higher level of abstraction used to locate resources.
Network addresses are fundamental to network communication, but they are not a direct ranking factor in SEO. However, the stability and reputation of an IP address (especially with shared hosting) can indirectly affect the deliverability and overall technical health of a website.
