The phrase "who is this" is commonly used as a question to inquire about the identity of a person or entity. Without additional context, the question "who is this" does not specify a particular individual or subject. If the question refers to a specific person, place, or thing, more context would be needed to provide a precise answer. If the inquiry relates to "WHOIS," it is a protocol and database used for looking up the registered users or owners of domain names and IP addresses on the internet. WHOIS information typically includes contact and administrative details of domain registrants and is useful for verifying domain ownership, contacting domain owners, and other administrative or legal purposes.
For example, "WHOIS" can be used to find out who owns a particular website domain or registered IP address. Please provide more context if a more specific identification is needed.
