Whois & Analysis for dlcache.com

An IP address (abbreviation of Internet Protocol address) is an identifier assigned to each computer and other device (e.g., printer, router, mobile device, etc) connected to a TCP/IP network that is used to locate and identify the node in communications with other nodes on the network.

IP addresses are usually written and displayed in human-readable notations, such as 172.16.254.1 in IPv4, and 2001:db8:0:1234:0:567:8:1 in IPv6.

WHOIS (pronounced as the phrase who is) is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information.

The protocol stores and delivers database content in a human-readable format.

The WHOIS protocol is documented in RFC 3912.

In computing, traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network.

The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection.

Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.

Ping, on the other hand, only computes the final round-trip times from the destination point.

The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network.

It associates various information with domain names assigned to each of the participating entities.

Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols.

By providing a worldwide, distributed directory service, the Domain Name System is an essential component of the functionality of the Internet, that has been in use since 1985.

A Uniform Resource Locator (URL), commonly informally termed a web address (a term which is not defined identically) is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it.

A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably.

A URL implies the means to access an indicated resource and is denoted by a protocol or an access mechanism, which is not true of every URI.

Thus is an URL, while is not.

URLs occur most commonly to reference web pages, but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.
