 Lets say this site is, hypothetically, [[http://scanme.nmap.org|scanme.nmap.org]]. So where to begin? Before you can start to do anything (dox, attack, shut down, etc) you first need to run some basic tools. You have to profile where this site intersects with the rest of the internet, and the real world. Lets say this site is, hypothetically, [[http://scanme.nmap.org|scanme.nmap.org]]. So where to begin?

 Every machine (or **host**) on the internet has an **IP address**, and every domain name resolves to an IP address. Domain names are only aliases for IP addresses because //whatever.com// is easier to remember than //187.158.173.109//. The inverse is not necessarily true. An IP may have no domain name pointing to it. Every machine (or **host**) on the internet has an **IP address**, and every domain name resolves to an IP address.

 [[wp>WHOIS]] is a query and response protocol that is used for querying databases that store an Internet resource's registered users or assignees. These resources include domain names, IP address blocks and autonomous systems, but it is also used for a wider range of other information.

-On all *nix based systems it's pretty easy to find out any available details about a domain. That's what the ''whois'' command is for. Every domain registrar runs a WHOIS database for the domains it is hosting. Their database usually contains information about the owner & assigned contacts of the domain, such as email, phone, and street address. Some registrars require that the administrative contact is a natural person, not an organization. Keep in mind that some domain owners will lie about this, which can be grounds for domain suspension, but it is hardly enforced. Some domain owners subscribe to privacy services (such as **Domains by Proxy** or **Withheld for Privacy**) in which case you will have to try another way to get the information.+**WHOIS** lookups are extremely easy to do.
