When it is not possible to have a static IP address, it is impossible to create a site. The domain name must be tied to a specific point in the Internet space. The greatness and diversity of the Internet was originally based on simplicity: everything is always accurate, static and stable - first of all, it concerns the addresses of all resources, nodes, servers, routers ...
The idea of dynamic DNS-DDNS appeared relatively recently and very quickly gained popularity. Network users who need a domain name (video surveillance, data exchange, access to a resource, communication with their own local network and devices in it), in the absence of their own static and constantly changing IP, can get what they want with almost any Internet connection via any provider.
DDNS Technical Support
The DDNS list is growing steadily. There are companies that provide the service for a long time and for free, there are those that have appeared recently. Both free and paid options for obtaining your own domain name are interesting, and choosing a company is a matter of taste and preferences of the consumer.
Almost all routers allow you to specify the DynDNS address and make the necessary settings. In each case, there may be its own peculiarities, but in any case, the connection of a static node on the Internet that provides the DDNS service and a point in the local network (video camera, server, computer, other device) connected to the router is fixed.
Technically, the whole procedure consists of registering on the website of the company providing the service, setting up the router and the computer on the local network.
As a result, the user receives his own unique domain name, usually of the third level. He is assigned a name and password, he provides his e-mail address. Next, the router is configured, it indicates the received data and establishes their connection with devices on the local network.
After performing a few simple steps, you can access the device inside the local network (at home, in the office) using the registered domain name from anywhere in the Internet space.
Companies providing DDNS service
The list of DDNSs is quite large, the geography of domain zones and the location of production servers make it possible to make a high-quality and reasonable choice of service. Well-known companies in the com domain zone:
- DynDNS;
- No-IP
- DNS-Free, etc.
In the domain zone ru work:
- dnsIP;
- dnsAlias;
- dyn-dns etc.
Usually the service is provided in the form of a third-level domain, and each company has its own list of DDNS servers in different domain zones located in different geographical regions, on paid or free terms.
Activation of the service lasts from day to three, consultations and support around the clock. A common practice has recently become more secure and began to satisfy the interests of users who do not want to pass their traffic through other people's servers.
Own private network or external DDNS?
When the question becomes critical, the user is prompted to install a special application on the computer - this is how his own private network becomes available. In such a network, you can access any services or programs using any protocol (port).
Not every DDNS service provides such a service. A common practice is to provide a client with a domain name and ensure that when accessing it, packets are sent to a client router that is preconfigured to work with a specific service. In the network controlled by this router, the necessary devices are configured.
Modern routers can have both their own DDNS services and a list of DDNS. The latter option may not include exactly the service that the client has chosen, therefore, when purchasing a router, it is advisable to clarify its capabilities regarding DDNS connection.
The list of free DDNS servers is quite extensive and is able to satisfy a demanding user. The quality of the service is constantly improving, however, before making a decision, everything should be carefully weighed.
This is the case when the value of information, traffic or personal security is more important than the economic parameter of a service. Paid service of dynamic IP, and even better - its own static IP address, is often more promising and cheaper than probable problems.
Dual DDNS service and data protection
When a decision is made to use the free DDNS option, but there is a strong desire to secure traffic or not to let the information flow from the surveillance cameras of your own home through other people's servers, you can divide the information flows in different directions or through various services.
There are many options. You can use, in particular, the cloudflare com service, the purpose of which is maintenance and security, you can discuss the protection of traffic and information with your own provider, which is always not indifferent to the interests of customers.
But if finances do not allow, you can develop your own strategy for using proven services.
Security is the ability to make the obvious inaccessible. Many valuables are more convenient to store on public display, but to make the appearance of accessibility is imaginary. High-speed Internet, DDNS in its own network, a thorough analysis of information flows and the content of the information used will create a secure system with minimal financial investment.
Mail and DDNS Service
A great addition to DDNS is the mail provided by pdd yandex ru. This service provides wide possibilities from a large volume of mailboxes and disk space to connecting your own domains to the Yandex competency zone.
An interesting feature of the service is the connection of user domains, the organization of an email service on them, access to them through the API and SMS notification of letters. These features are pdd yandex ru. allow optimizing and building work with DDNS in an optimal way, although this option will require time to develop a work plan and, most likely, to program your own ideas.
The ideal is still to use the available capabilities without unnecessary costs, so that the obvious is not noticeable to outsiders, but is available for tasks.
In each case, such a solution is unique, but it takes time to analyze the objectively acting circumstances and available resources that provide the DDNS service. It is important to consider the technical specifications of your own equipment, the routers and communication channels used.
DDNS and router
Sometimes good results in the ratio of security and cost can be achieved at the intersection of technologies - when using one idea through another idea.
By and large, the routers and DDNS list items to be made available to the client are one part of the task. The company selected by the client may simply not be on the list, but the option of the DynDNS service from the router manufacturer will be imposed.
A collision of access rights and network resources is possible. It’s good when a client is assigned a domain name - he can use it to access a video camera in his own house. What if there are ten such cameras, and the child has his own computer, which also needs to be controlled? Functionally, a router is a rather limited product, and not every model has a sufficient number of ports, not to mention the features it provides.
DDNS and Remote Access Windows / Linux
This is not an ideal solution, but a DDNS service providing remote access to the host computer on a local network (at home, at work) is a worthy option.
The network that the router forms controls one computer. Through it, all network devices are available (other machines, printers, faxes, DVRs, sensors, etc.).
Having remote access to the host computer, you can control the entire network. In a Windows environment, an idea can be implemented through remote access, in a Linux environment through an SSH protocol.
