DNS Lookup: Check Domain Names or IP Address

This page will help you find public information about any Web site or Web server. Using this query, you can get an IP address of a host by its name, or a host's name by its IP address. We will also try to find a location where this domain was registered and check against our free e-mail services list. In addition, we give you a link which helps you find registration information, such as an administrator's e-mail, etc.

Domain—part or the entirety of a domain name, used to identify a machine or virtual host on the Internet. More...

A domain name is a name of a computer on the Internet that distinguishes it from the other systems on the network. They are sometimes colloquially (and incorrectly) referred to by marketers as "web addresses". More...

The Domain Name System or DNS is a system that stores information about hostnames and domain names in a type of distributed database on networks, such as the Internet. Of the many types of information that can be stored, most importantly it provides a physical location (IP address) for each domain name, and lists the mail exchange servers accepting e-mail for each domain.

In computing, host is any machine connected to a computer network, a node that has a hostname. A more specific meaning is that hosts are servers. More...

An IP (Internet Protocol) address is a unique identifier used by computers to refer to each other when sending information through the Internet. Converting to IP addresses that look like 38.103.63.18 from the more convenient form of domain addresses, such as www.translatorscafe.com, is done via the Domain Name System (DNS). The process of conversion is known as resolution of the domain name.

On any given network, the IP address must be unique among all the host interfaces that communicate through this network. Internet service providers usually provide users of the Internet with a host name in addition to their numerical IP address.

The IP addresses of users browsing the World Wide Web are used to enable communications with the server of the web site. The IP address of the sender can be usually found in the header of email messages.

Depending on the type of the Internet connection, the IP address can be the same every time a user connects (called a static IP address), or different (called a dynamic IP address). In order to use a dynamic IP address, there must exist a server or other equipment that can provide the address. IP addresses are usually given out through a service called DHCP or the Dynamic Host Configuration Protocol. More...

Virtual hosting is a method that servers such as Webservers use to host more than one domain name on the same computer, sometimes on the same IP address. More...

WHOIS is a TCP-based query/response protocol which is widely used for querying a database in order to determine the owner of a domain name, an IP address, or an autonomous system number on the Internet. More...
