Working of Domain Name Servers

Domain Name System, or DNS, even without realizing it. DNS is a protocol within the set of standards for how computers exchange data on the Internet and on many private networks, known as the TCP/IP protocol suite. Its basic job is to turn a user-friendly domain name like “prewebhost.com” into an Internet Protocol (IP) address like 70.42.251.42 that computers use to identify each other on the network. It’s like your computer’s GPS for the Internet.

When you enter a URL into your Web browser, your DNS server uses its resources to resolve the name into the IP address for the appropriate Web server. See more computer networking pictures.

Computers and other network devices on the Internet use an IP address to route your request to the site you’re trying to reach. This is similar to dialing a phone number to connect to the person you’re trying to call. Thanks to DNS, though, you don’t have to keep your own address book of IP addresses. Instead, you just connect through a domain name server, also called a DNS server or name server, which manages a massive database that maps domain names to IP addresses.

Without DNS servers, the Internet would shut down very quickly. But how does your computer know what DNS server to use? Typically, when you connect to your home network, Internet service provider (ISP) or WiFi network, the modem or router that assigns your computer’s network address also sends some important network configuration information to your computer or mobile device. That configuration includes one or more DNS servers that the device should use when translating DNS names to IP address.

Managing Domain Name Servers

Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses.

This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses. 

Information from all the domain name servers across the Internet are gathered together and housed at the Central Registry. Host companies and Internet Service Providers interact with the Central Registry on a regular schedule to get updated DNS information. 

When you type in a web address, e.g., www.prewebhost.com, your Internet Service Provider views the DNS associated with the domain name, translates it into a machine friendly IP address (for example 216.168.224.70 is the IP for prewebhost.com) and directs your Internet connection to the correct website. 

After you register a new domain name or when you update the DNS servers on your domain name, it usually takes about 12-36 hours for the domain name servers world-wide to be updated and able to access the information. This 36-hour period is referred to as propagation.

Security Hardening

it's secure

Security part is taken very seriously now a days, but as with any other system there are potential security issues that may arise if some basic security precautions aren’t taken.

As per the security concerns; if you have specific security concerns or doubts, you should discuss them with people whom you trust to have sufficient knowledge of computer security

Knowing Security?
Fundamentally, security is not about perfectly secure systems. Such a thing might well be impractical, or impossible to find and/or maintain. A secure server protects the privacy, integrity, and availability of the resources under the server administrator’s control.

Qualities of a trusted web host might include:

Readily discusses your security concerns and which security features and processes they offer with their hosting.
Provides the most recent stable versions of all server software.
Provides reliable methods for backup and recovery.
Decide which security you need on your server by determining the software and data that needs to be secured. The rest of this guide will help you with this.

Security Themes
Keep in mind some general ideas while considering security for each aspect of your system:

Limiting access
Making smart choices that reduce possible entry points available to a malicious person.
Containment
Your system should be configured to minimize the amount of damage that can be done in the event that it is compromised.
Preparation and knowledge
Keeping backups and knowing the state of your WordPress installation at regular intervals. Having a plan to backup and recover your installation in the case of catastrophe can help you get back online faster in the case of a problem.
Trusted Sources
Do not download from untrusted sources.

Vulnerabilities on Your Computer
Make sure the computers you use are free of spyware, malware, and virus infections .No amount of security on your web server will make the slightest difference if there is a keylogger on your computer.

Always keep your operating system and the software on it, especially your web browser, up to date to protect you from security vulnerabilities. If you are browsing untrusted sites, we also recommend using tools like no-script (or disabling JavaScript/flash/java) in your browser.
