Managed DNS: Its Time Has Come

Reading Time: 3 minutes

Domain Name SystemThe Domain Name System is fundamental to the functioning of the internet and works so well that we rarely consider how it works. Most people do not even realize that we have options to choose from that can improve our internet performance and enhance our security.

Before I get to the choices, let’s review DNS.

What is the Domain Name System (DNS)
I’ll start with what you probably already know. The Domain Name System (DNS) is often compared to phone book. If I want to call someone I use their name to lookup their number.

To communicate with another computer on the internet your computer needs a numeric IP address, analogous to the phone number. However, when using email and the web your computer uses a registered domain name and the Domain Name System to lookup an associated IP address. For example, the domain name example.com is associated with the IP address 192.0.43.10.

How Does DNS Work?
DNS consists of a network with different types of servers that are organized in a hierarchy.

Root Server: A single server node that can provide the location of the 13 Domain Servers.
Root Name Servers: 13 server nodes that can provide the location of the Name Servers for specific domains (.com, .edu, .uk, etc). There are actually many more than 13 physical servers per node.
Authoritative Name Servers: These are servers where domain name/IP address association data have been obtained from an original source. The next step after registering a domain name is to provide the name to your web and/or email host to add the name to an Authoritative Name Server.
Other Name Servers: These are name servers that obtain their data by querying other name servers and storing the data in cache.

This is all important to understand because to use domain names your computer or network must be configured to connect to a specific name server to “resolve” a name to an IP address.

Choosing your own DNS Server
When you connect to the internet, most of the time you are setup with a name server provided by your Internet Server Provider.  This is almost certainly an “Other Name Server” mentioned above. However, you actually use any name server that you have access to.  This means you have choices.

Setup your own DNS? Maybe, maybe not
The first choice is to setup your own DNS server. It’s actually not very hard and the software is available for free. However, note the following:

o  You cannot setup your own DNS for a web site on a shared server.
o   It will only be as secure as your own network.
o  To be available 24/7 your server has to be running 24/7.

It can be a fun and somewhat geeky thing to do to setup your own DNS server. However, it’s something to leave to large corporations with their own IT staffs. Even so, the company is assuming the risk of downtime.  For most people, especially small and medium size e-commerce business it is way to risk. If your DNS is down, your site is down.  Your business is down.

Managed DNS? A better idea!
A much better idea is to sign up with a managed DNS service to host your DNS.  These are companies that have established their own network of DNS servers and add features to improve performance, security and protections. DNS performance can be very important in how fast a web page loads.

Using advanced routing technologies such IP Anycast and GeoDNS, they can improve resolution times by as much as .5 seconds.  If a page has 3rd party content such as advertising, there could be multiple DNS resolution lookups to display the page.  If 5 resolutions are needed you might save 2.5 seconds, an eternity when waiting for a page to display.

Managed DNS providers offer additional features that you do not get from your ISP:

o  Security: Protection against malware, Denial of Service Attacks (DOS), phish blocking, blacklist prevention, etc
o  Content filtering
o  100% uptime SLAs
0  Web interfaces for managing DNS and DNS records

Managed DNS providers, such as Comodo,  charge a monthly fee for the services. Depending on the number of domains covered and the amount of network traffic it could be between $25 and $100 per month.

What is Semantic UI CDN?

Semantic UI React supplies React components, while Semantic UI CDN provides themes such as CSS stylesheets.

Semantic empowers designers and developers to create a specific UI vocabulary.

Current version 2.4.2

<head>
<script src=”https://code.jquery.com/jquery-3.1.1.min.js” crossorigin=”anonymous”></script>
<link rel=”stylesheet” href=”https://cdn.jsdelivr.net/npm/semantic-ui@2.4.2/dist/semantic.min.css”>
<script src=”https://cdn.jsdelivr.net/npm/semantic-ui@2.4.2/dist/semantic.min.js”></script>
</head>

The rise of the digital economy changed the way we communicate, search for information, shop for products and services, decide, and many other tasks dramatically. As the digitization of virtually everything continues unabated, an endless supply of content is being generated, and devices and interfaces are becoming increasingly intuitive. Taking advantage of this opportunity, businesses of all sizes have embraced content marketing to sell products and services to consumers around the world. The speed of the websites they visit is essential for digitally empowered customers.

So, if you want to have low bounce rates and high retention rates, your website needs to be fast and highly responsive. The Content Delivery Network ( CDN) can make your website faster by reducing the distance between the user and the server of the site, compressing files, and optimizing connections. If you want a responsive web design, you can use Semantic CSS UI, an open-source framework that uses Cascading Style Sheets (CSS) class names such as words to generate a natural language style library.

The web design is responsive when it automatically adjusts content to look good on all devices, from mobile phones to tablets, laptops, and desktops. Semantic UI makes it possible to use human-friendly HTML. It can be installed either locally or using a hosted CDN.

What Are the Benefits of using Semantic UI CDN?

Semantic UI tasks can be effectively integrated with the Semantic UI CDN in the current website development tools.

Examples of semantic UI

For example, if you want to design a list using semantic UI CDN, you can simply add a few lines of code to your project using the list component CDN.

Research shows that 47% of visitors expect a website to load within 2 seconds, 40% leave a website that is loaded for more than 3 seconds, and 79% that are slower. Imagine the potential revenue of those who leave your site and never return because your web pages won’t load quickly enough.

Companies such as Akamai, MaxCDN (now StackPath), Amazon CloudFront, and Cloudflare CDN distribute edge server texts, documents, graphics, scripts, multimedia files, apps, and web tools worldwide. The CDN would connect the user to the server nearest to the location of the site instead of to the main server thousands of miles away to speed up the delivery of content.

In addition to boosting website load times, CDN reduces bandwidth costs, enhances overall content availability, and improves the security of your site. The amount of data generated by a server is decreased by caching information, distribution of inbound web traffic through several servers, and routing of user requests to the closest edge node. As a result, the CDN can reduce website hosting costs. The advantage of faster loading times is that it improves Google’s page load frequency, increasing the SEO ranking of your site.

When it comes to security, a CDN helps protect your website and ensure it is secure using fresh TLS / Secure Sockets Layer (TLS / SSL) data encryption and authentication certificates. TLS / SSL) certificates also guarantee data integrity by manipulation and falsification detection.

Most organizations have RTL (Right To Left) CSS and JavaScript in Semantic UI for CDN support. React, Meteor, and Ember.js provide construct tools that integrate with Semantic UI. All modern JavaScript bundlers fully support the Semantic UI React. Snapchat is a great organization that uses Semantic UI.

Select Right CDN at Low Cost?

With so many companies offering network content delivery services, it is not easy to select the right one. The following tips can help you find the CDN that fits your needs.

Performance

You are hiring a CDN service provider, and you want your website to load faster so that you know how easily the edge servers will deliver your files. In this respect, you have to analyze and compare main performance metrics such as latency and efficiency during regular and peak traffic times. Ask if the CDN can reduce latency and hops, if its responses and load times are satisfactory and if it can cope with unexpected network traffic spikes so that your site can operate instead of decreasing.

Security

In addition to making the loading of your websites faster, a CDN will improve the protection of your site. In particular, a CDN service provider should be able to mitigate cybersecurity threats such as DDoS attacks, ransomware, and phishing, keeping your website and your business safe.

Technical support

Responsive technical assistance is an essential factor in choosing a CDN. Check the ticket response time for the content delivery network service, whether it has a team that can help 24 hours a day via email and phone, and if they can fix any problems promptly.

Functionality/Features

A secure CDN should include tools and features that optimize the performance of your website, including instant content removal from any edge server, an intuitive user interface that helps you to set up and manage your web resources quickly, a network that delivers content as quickly as possible, or a forum for monitoring traffic statistics in real-time.

Cost

There are content distribution networks that can be used free of charge, while others cost hundreds to thousands of dollars. They’re doing the same thing, which is to make the website load faster. Compare pricing plans and choose the one you think offers the best value to your money.

The Bottom Line

Your website is a powerful tool to encourage your business for a global audience, but it can be responsible if it goes slowly. Whether unoptimized images, voluminous codes, too many HTTP queries, or JavaScript problems are accountable for your website’s slower performance, a content delivery network can help. Semantic UI CDN CSS is also supported by A CDN to create websites that are responsive to each device.

Cyber Attack on Iran Nuclear Facility by USA or Israel

Avatar

Iran has issued a direct warning to two nations- the United States and Israel; that it will launch a retaliation related cyber attack, if any of the two nations is found guilty, in digitally disrupting its Natanz Nuclear Factory mid-last week.

Highly placed sources say that a fire broke out in the facility last week, with Iran suspecting a digital hand of either Israel or US in the cyberattack propelled nuclear facility disruption.

Islamic Republic News Agency (IRNA) acknowledged the news by stating that the fire mishap was a result of a cyber-attack and the Ministry urged the two nations to revise their policies against Tehran.

Note 1-Iran’s Natanz Nuclear Facility is used for Uranium Enrichment and is under the constant vigil of the UN Nuclear Watchdog- International Atomic Energy Agency(IAEA).

Note 2- In the year 2010, the US launched a digital attack on the Natanz nuclear facility which at that time was being used for electricity generation in Iran. And sources add that a newly developed Stuxnet Computer Virus to disrupt the facility by Washington or Tel Aviv.

Note 3- Now, Iranian officials claim that the latest fire disruption in the facility was also due to the digital invasion, but failed to pin down the incident on the two nations due to lack of evidence. However, the Defense Intelligence Agency who is probing the incident has warned that if the nation led by Donald Trump is found guilty in the attack, it has to get ready to face serious consequences over the incident.

The UK to axe Huawei from 5G network build due to security fears

Avatar

Published

on

Britain is all set to reconsider its decision of allowing Chinese company Huawei to build 5G network infrastructure in its nation, as a newly drafted intelligence report has confirmed that the installed infrastructure will only guarantee safety from Chinese espionage just for 7 years.

According to research conducted by Daily Mail, the National Cyber Security Center(NCSC) has concluded that Huawei 5G products are not secure and so the ban imposed by the United States against the Chinese vendor is completely true.

Britain’s Ministry is reported to approve the ban after a cabinet ban to be held at the end or early next week and so the purchase of Huawei’s 5G equipment due to be done in November this year might take a U-Turn.

Oliver Dowden, the Cultural Secretary has acknowledged that the Ministry has received the latest intelligence report from NCSC, a cyber arm of GCHQ, and said that a formal announcement on the matter will be announced shortly.

Mr. Dowden also reiterated the fact that decisions such as these definitely need some time to come to a consensus and admitted that there is a chance of Huawei’s entire technology getting scraped from Britain’s Telecom network by the end of 2029.

Note 1- A source from Huawei on the condition of anonymity reacted to the news and stated that the decision of NCSC to scrap Huawei from the 5G network build project might be a result of a pressure coming from Trump Administration.

Note 2- NCSC has clearly specified in its report that it’s better to replace Huawei with a company headquartered in western countries as reconsidering Asian alternatives like Japan’s NEC might be less trustworthy.

Note 3- Matt Hancock the Health Secretary of UK told Sky’s Sofy Ridge that Britain will take the decision on Huawei keeping the best interests of its populace.

Note 4- As per some trade analysts working for Alibaba, if Britain imposes a ban on the use of 5G products of Huawei in its network build, then it can witness a loss of $13 billion in GDP gains in the next 10 years.
