List of DDNS, instructions for setting up

When it is not possible to have a static IP address,you can not create a website. The domain name must be linked to a specific point in the Internet space. The greatness and diversity of the Internet was initially 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 appearedrelatively recently and very quickly gained popularity. Users of the Network who need a domain name (video surveillance, data exchange, access to a resource, communication with their own local network and devices in it), when absence of its own static and the presence of an ever-changing IP, can get what it wants in almost any type of Internet connection through any provider.

Technical support of DDNS

The list of DDNS 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 the choice of the company is a matter of taste and preferences of the consumer.

Virtually all routers allow you to specifyaddress DynDNS and make the necessary settings. In each specific case, there may be specific features, but in any case, the static node is connected to the Internet, which provides the DDNS service and a point on the local network (video camera, server, computer, other device) connected to the router.

Technically, the whole procedure consists in registering on the website of the company providing the service, configuring the router and the computer in the local network.

As a result, the user gets their owna unique domain name, usually the third level. He is given a name and a password, he provides his e-mail address. Next, the router is configured, it indicates the received data and establishes their connection with the devices in the local network.

After performing a few simple steps, you can access the device inside the local network (at home, in the office) via the registered domain name from anywhere in the Internet space.

Companies providing DDNS service

The list of DDNS is large enough, the geography of domain zones and the location of working servers make it possible to make a qualitative and reasonable choice of services. Known companies in the domain zone com:

• DynDNS;
• No-IP;
• DNS-Free, etc.

In the domain zone ru work:

• dnsIP;
• dnsAlias;
• dyn-dns, and so on.

Usually the service is provided in the form of a domainthird level, each company has its own list of DDNS servers in different domain zones located in different geographic regions, under paid or free conditions.

The activation of the service lasts from one day to three days,consultations and support around the clock. The usual practice has recently become more secure and began to satisfy the interests of users who do not want to skip their traffic through other people's servers.

Own private network or external DDNS?

When the question becomes critical, the userit is proposed to install a special application on the computer - so your own private network becomes available. In such a network, you can access any protocol (port) to any services or programs.

Not every DDNS-service provides such a service. The usual practice is to provide the client a domain name and ensure, when accessing it, the translation of the packets to the client's router, which is pre-configured to work with a specific service. In the network controlled by this router, the necessary devices are configured.

Modern routers can have both their ownDDNS services, and a list of DDNS. The latter option may not include exactly the service that the client has chosen, therefore, when acquiring a router, it is advisable to specify its capabilities in connection with the connection of DDNS.

A list of free DDNS servers is enoughIt is large and able to satisfy a demanding user. The quality of the service has been steadily increasing, however, everything must be carefully weighed before making a decision.

This is the case when the value of information,traffic or own security is more important than the economic parameter of the service. Paid dynamic IP service, and even better - own static IP-address, are often more promising and cost less than probable problems.

Double DDNS service and data protection

When a decision is made to use a freeversion of DDNS, but there is a confident desire to secure traffic or not to pass the flow of information from CCTV cameras of your own home through other people's servers, you can divide information flows in different directions or through various services.

There are many options. You can use, in particular, the service cloudflare com, whose purpose is to maintain and ensure security, we can discuss the issue of protecting traffic and information with its own provider, which always cares about 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 inaccessiblethe obvious. Many valuable things are more convenient to store on a general review, but to make sure that the visibility of accessibility is imaginary. High-speed Internet, DDNS in its own network, careful analysis of information flows and content of the information used will make it possible to create a secure system with minimal financial investments.

Mail and DDNS service

An excellent addition to DDNS is the mail thatprovides pdd yandex ru. This service provides ample opportunities from a large volume of mailboxes and disk space to the connection of their own domains in the competence area of ​​Yandex.

An interesting feature of the service is the connectionuser domains, organization of mail services on them, access to them via API and SMS-notification of letters. These features pdd yandex ru. allow to optimize and build 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.

Ideal is still the use of available options at no extra cost, so that the obvious was not noticeable to outsiders, but is available for the tasks to be solved.

In each specific case, such a decisionis unique, but it takes time to analyze the objectively acting circumstances and the available resources that provide the DDNS service. It is important to take into account the technical characteristics of your own equipment, used routers and communication channels.

DDNS and router

Sometimes good results in the ratio of safety and cost can be achieved at the interface of technology - by using one idea through another idea.

By and large, routers and DDNS list items,which is to be placed at the disposal of the client, is one part of the task. The company chosen by the client simply might not be on the list, but the variant of the DynDNS service from the router manufacturer will be imposed.

A conflict of access rights and Web resources is possible. Well, when the client is assigned a domain name - he can through it to turn to the 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, the router is a fairly limited product, and not every model has a sufficient number of ports, not to mention the capabilities it provides.

DDNS and Remote Access Windows / Linux

It can not be said that this is an ideal solution, but DDNS-service that provides remote access to the main computer in a local network (at home, at work) is a worthy option.

The network, which forms the router, is controlled by one computer. All network devices (other machines, printers, faxes, DVRs, sensors, etc.) are accessible through it.

Having remote access to the host computer, you can monitor the entire network. In the Windows environment, the idea can be implemented through remote access, in a Linux environment - via the SSH protocol.
