Free DNS vs Premium DNS

الـ DNS في حد ذاتها هي ميزة مهمة من خلالها يتم ربط موقعك بدومين (نطاق) وهذه الميزة في الغالب تكون مجانية أو من ضمن قيمة الاستضافة لكن هنالك خدمة DNS متقدمة مدفوعة يفترض أن توفر ميزات اضافية (ولذلك تدفع عليها) هذه الميزات الإضافية لا تحتاجها إلا المواقع الكبيرة المعقدة

مع التنبيه بعض الشركات تسوق خدمة الـ DNS العادية (المجانية) على أنها خدمة DNS متقدمة وحينها بتدفع فلوس على الفاضي مع أنه لا فرق

وكذلك بعض الشركات الإضافة تعطيك ميزات الـ DNS المتقدمة بشكل مجاني (ضمن فلوس الاستضافة)

تنبيه آخير الشركات التي توفر خدمة DNS متقدمة مدفوعة الثمن تتفاوت في الميزات اللي تقدمها لك فيجب أن تعرف بالضبط ما هي الميزات الموجودة التي تدفع عليها

الميزات الإضافية

عبارة عن تقنيات الغرض منها في الأساس زيادة سرعة خدمة الـ DNS العادية و زيادة الحماية

مثلاً
ميزة load balancing فمثلاً لو كان موقع مشهور جدا وعليه اقبال شديد بحيث مثلاً الآلاف الزوار يفتحون موقعك بنفس الوقت هذا قد يسبب ضغط على سرفر الـ DNS فلا يستطيع تلبية جميع الطلبات وحينها لن يظهر موقعك لبعض الزوار وسيحتاجون لتكرار محاولة زيارة موقعك لكن مع ميزة load balancing يتم عمل موازنة وتوزيع لطلبات الزوار على أكثر من سرفر DNS وحينها لا يحصل ضغط على السرفر ويتمكن الجميع من زيارة موقعك

Types of DNS Servers

Most, but not all, domain name registrars offer nameserver services when you register a new domain. Domain owners have the choice of which hosting they prefer. The specifications and limitations vary between the various types.

Self-hosting - DNS can be self-hosted by running DNS software on generic Internet hosting services.

Shared hosting - is when a number of hosting accounts are located on one server, with some sharing the same IP address. These types of plans have limited features and resources, and are not recommended for sites with high resource consumption.

Managed DNS - this is a service that organizations use to outsource DNS to a third-party provider for reasons of simplicity. Another company sets up and maintains their DNS servers.

Virtual Private Server (VPS) - Is where one server acts like a dedicated server. However, a physical server is partitioned into multiple servers, each with their own operating system. VPS users have more control over their nameservers. Each receives a specified share of the resources of the physical server, and are completely isolated from each other, meaning they do not affect each other if they experience problems. Webmasters implement VPS to cut the cost of a dedicated server.

Dedicated DNS - Dedicated hosting providers tend to be the most powerful option, they are faster and more reliable because they are designed for hosting DNS query traffic and nothing else.

Free DNS - covers the basic DNS requirements for most websites.

Premium DNS - includes premium features to keep your site secure with guaranteed uptime, better support and more.

Premium DNS Features

Every commercial website should use premium DNS to guarantee they are both safe and available to their customers. There are distinct advantages of paying for a DNS: improved site availability, faster performance, and minimal security gaps.

Premium DNS involves pointing your domain to premium nameservers and setting up your records on these nameservers.

These are the typical features you should expect from premium DNS services:

• Many premium DNS service providers offer Dynamic DNS (DDNS). DDNS automatically maps internet domain names to IP addresses, allowing you to access your home computer from anywhere in the world. Unlike standard DNS, which only works with static DNS, DDNS is designed to work with changing IP addresses, which is a good fit for home networks.
• Secondary DNS - This premium feature is particularly useful if you manage your nameservers and want a backup or redundancy. A secondary nameserver will ensure that your domain never goes offline.
• Management interface - A well-configured DNS dashboard lets you manage and make updates to your DNS easily online, instead of going through customer services to redirect your DNS using different record types, for example.
• Reporting - Advanced reporting is available with premium services, including analytics that report the source country and record type for queried hostnames.
• Administrative Control - Admin controls let you delegate administrator privileges with ease.
• Two-way authentication - Protect your domain with two-factor login authentication.
• DNS templates - Save time by applying DNS templates to the domain names in your Premium DNS Dashboard. This is useful if you are managing multiple websites.
• Fast Performance - Redundancy - Guaranteed service level agreement for DNS resolution between 99-100% with paid DNS plans.
• Queries per month - Premium DNS services guarantee domain resolution on millions of queries per month.
• Close security gaps - Hackers can use your IP address to point to a malicious IP address to trick users into divulging important information and sometimes even money. Premium DNS hosting provides an additional layer of security for your website and thus additional protection from hackers.
• DNSSEC support - Increase your domain name security with managed DNSSEC. Premium nameservers provide support and security for top level domains to protect them from attacks. Hackers have been known to infiltrate the DNS lookup process, directing users to deceptive sites for password and account collection, for example. DNSSEC is employed to protect domains from any vulnerabilities in the DNS system.
• First-class customer service. DNS can get a bit tricky, so having professional support as and when you need it is invaluable to a smooth running website.
• It is easy to use. Experts and beginners will find the interface for managing their nameservers simple to navigate.

Paid DNS services offer advanced features to manage your DNS, combined with a higher level of support and faster loading times. If you want super fast IP address resolution, you need a premium nameserver.

The fact of the matter is, extremely quick websites leave a good impression. People are impatient online. If you can shave a few milliseconds off the time it takes for people to discover your site via DNS, you might see some marginal gains.

Fast speeds aren’t only to impress your site visitors; you’ll want to impress Google with your site’s loading and availability. If your site loading times aren’t up to scratch, your search engine rankings and subsequent click rates could take a hit (DNS capabilities make up a huge part of site load times).
