Dynamic DNS SERVICE – SOLUTION FOR DYNAMIC IP

What is Dynamic DNS service?

dynamic DNS

Dynamic DNS service is a service that allows you to associate a dynamic IP address of a device (such as a router or server) with a fixed domain name. Dynamic IP addresses will always change, so it can make remote access difficult.

Dynamic DNS solves this problem by automatically updating information about the device’s new IP address every time it changes. At that time, the domain name you registered with the Dynamic DNS service will always be identified to the device’s latest IP address. This allows you to easily access your device from anywhere via a fixed domain name, instead of having to remember a dynamic IP address.

Dynamic DNS is commonly used for FTP servers, game servers, security cameras, or any device you want to access remotely without having to worry about changing their IP address.

Why do some IP addresses change?

In the early days of the Internet, IP addresses rarely changed, which made domain name management much simpler. But the rapid growth of the web and home computers with Internet access has created a shortage of available IP addresses. This led to Dynamic Host Configuration Protocol (DHCP), which allowed ISPs (Internet Service Providers) to dynamically assign IPs to their users.
ISPs will often maintain a shared pool of IP addresses and assign them to users as needed. Although the advent of IPV6 has alleviated the shortage of IP addresses, ISPs still often use DHCP because it is more cost-effective than providing static IPs.

What is the difference between DNS and Dynamic DNS?

The DNS service is a global service that converts readable domain names into numeric IP addresses. The DNS server performs the conversion of domain names into IP addresses and decides which server will provide information to the user.

Dynamic DNS (DDNS) is a variation of DNS that automatically updates the IP address associated with a domain name in real time. DDNS extends the flexibility of DNS, allowing organizations and individuals to maintain connectivity and accessibility even when IP addresses change.

DNS is supported by all popular DNS servers and is used globally to convert domain names to IP addresses. In contrast, DDNS requires support from specific DDNS providers. Organizations must subscribe to DDNS services and configure their devices to work with their chosen DDNS provider.

What are the use cases of Dynamic DNS?

Dynamic DNS provides flexibility, convenience, and improved accessibility in the following scenarios:

Remote access

With Dynamic DNS, you can remotely access internal network resources such as web servers or remote desktop services. Employees can access these resources remotely using domain names associated with dynamic IP addresses. This is especially useful for organizations with remote employees, branch offices, or employees who travel frequently.

Storage service

Having a static IP address for hosting can be expensive, especially for small businesses. Early-stage startups often use Dynamic DNS to host services or applications on their internal infrastructure. They can host websites, FTP servers, game servers, or any other service that requires a consistent and easily accessible domain name.

Remote monitoring

Organizations that deploy remote surveillance camera systems often use Dynamic DNS to access and manage these systems. First, they associate the domain name with the monitoring device’s dynamic IP address. Security staff or administrators can then access live data sources, monitor security events, and manage systems from anywhere with an internet connection.
