Whois & Analysis for dnssouls.com

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 on the Internet, that has been in use since 1985.

This list of DNS record types is an overview of resource records (RRs) permissible in zone files of the Domain Name System (DNS).

It also contains pseudo-RRs.

A name server is a computer application that implements a network service for providing responses to queries against a directory service.

It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component.

This service is performed by the server in response to a service protocol request.

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.

Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices.

Invented by Ray Tomlinson, email first entered limited use in the 1960s and by the mid-1970s had taken the form now recognized as email.

Email operates across computer networks, which today is primarily the Internet.

Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging.

Today's email systems are based on a store-and-forward model.

Email servers accept, forward, deliver, and store messages.

Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages.
