What exactly is the Dynamic DNS idea?
DDNS refers to Dynamic DNS, or, more precisely, Dynamic Domain Name System. It is a service that associates IP addresses with online domain names. You can access your home computer using a DDNS service from anywhere in the world.
In the same way that the internet’s Domain Name System (DNS) advertises a public name to potential users, DDNS accomplishes a similar goal.
However, DDNS is also made to support dynamic (changing) IP addresses, such as those given by a DHCP server, in contrast to DNS, which only functions with static IP addresses. Because home networks typically acquire dynamic public IP addresses from such an ISP, DDNS is a suitable fit for them.
How does DDNS operate?
A DHCP server that operates on a system or provider-based software is used to implement several DDNS services. When changes are discovered, the DDNS client notifies resolvers of any required arguments for http or https URL queries. In addition, when DDNS is set up, the program or DHCP server notifies all systems of any changes to an application’s or domain’s IP address. This guarantees that service is never interrupted and that updates to IPs are immediately disseminated.
Why is using Dynamic DNS essential for you?
There are several advantages. Here are a few illustrations:
- You keep browsing the internet. It will reduce downtime by automatically updating the A or AAAA record. Therefore, accessing gadgets or services online will still be possible.
- Incredibly simple. For example, IP cameras for security only require a single installation. The username and password are required to configure the Dynamic DNS service on your router.
- Static IPs have higher costs. If you have a lot of devices, it will be far more economical to pay for one DDNS service. Each static IP address could cost more money to purchase.
- Simple, automatic configuration: When using a dynamic IP address, the DHCP server assigns the device the following available IP address. You are not required to do anything.
- Improved security: A dynamic IP address makes it more difficult for a possible threat to target your software.
Dynamic DNS provides an appropriate and reasonably priced alternative to purchased static IP numbers.
Negative aspects of a Dynamic DNS
- May restrict remote access: Using a Dynamic DNS could make it difficult for your program to establish a connection, depending on your remote access software. Avast SecureLine VPN and other VPN services excel in this area.
- Less precise geolocation: If your IP address is dynamic, your geolocation services may need to be fixed since you may continue to use an address that is no longer accurate for your current location.
FAQ
What distinguishes Dynamic DNS (DDNS) from DNS?
DNS has a capability known as Dynamic DNS. The IP addresses and name mapping were manually entered in static early DNS systems. The IP mappings are automatically updated by Dynamic DNS whenever they change.
How can I locate my outside IP address?
Enter what’s my IP address into Google.
Is Dynamic DNS synonymous with port forwarding?
No! Port forwarding allows a service to be accessed via an Internet address (external address). DDNS gives this external address a name and updates it if the address changes.
Do DDNS and DNS share the same port?
Yes. This is udp/tcp port 53.
Conclusion
We can all agree that DDNS is a precious service. So. it’s good to give it a chance and try it!
