Move the website home, you can only: pull the line? However, the price is too expensive, and many ordinary users can only hope. Managed server? Not only the price is high, but also maintenance is not convenient. Rent space? The function is greatly limited, and it is also very unsafe.
"The new generation of Internet information is released, and the future is likely to replace traditional information publishing methods such as virtual host and host hosting, and become the mainstream of the market." Today, in the broadband Internet, China's IP resources are increasingly shortage. No public network IP is a major feature of the messenger network, really "as long as you can go online, you can release the website". If you use a broadband Internet access (such as ADSL, cell broadband), you have a plenty of website publishing bandwidth. Use the messenger network to publish your own website using your existing Internet conditions.
The messenger network is considered to be similar to dynamic DNS. In fact, the messenger network is essentially different from the dynamic domain name (DDNS) system.
Is it a dynamic DNS?
What is dynamic domain name service
When you use PSTN, ISDN, ADSL, your IP address is dynamically allocated with each dial, if there is such a domain name on the network, regardless of your address, point to your address, so you can With this domain named customers with fixed services, companies or individuals can easily erect emails and other Internet servers in the enterprise or home, and build an online home as you want. · There is no need to apply for host hosting, virtual hosts, special lines and other services. · Use existing any online channels to publish the internal website to the Internet. · Data is placed in their own home, the security is extremely high! · Even if there is no legitimate IP address on the Internet, we can also publish a website on the Internet. · The website can have a formal Internet top-level domain, you can also use the Domain Name Service Provider for your free secondary domain name. · Your website system can be limited by the number of servers, not limited by content complexity.
Comparative Analysis of Network Pass and Dynamic DNS
The messenger network is not dynamic DNS, but a powerful system. Compared to dynamic DNS systems, the messenger network has the following 4 points based on dynamic DNS:
1, no public network IP
The dynamic domain name system is to resolve a domain name to a variable IP address, so users who must have public IP can be used. In China's reality is that it is not a public IP address. For example, many office buildings, although there are fiber to the building, but when you reach each user, allocated the private network IP address, so these users inside the building cannot use a dynamic domain name system. Another, for example, ADSL users, the dialing process gains a public IP address. And this IP address is only assigned to the host of the dial, and there is no public IP in any of the host through the agent online. With a dynamic DNS system, it is impossible to meet the above situation, if you want to use any of the host to implement the website release or office automation system, you cannot be implemented.
It can be very convenient to solve the problem. Because the messenger network does not require public IP, any computer that can access the public network can issue information to the public network.
2, support the internal network multi-host release
Because of the need for public IP, the host of the internal network can be used as a host with a public IP, using the letter. For example, a corporate system implements WWW sites, FTP, OA functions, respectively, and can be easily implemented.
The function of multi-host issues is unable to realize the dynamic domain name system.
3, no domain cache defect
The dynamic domain name cannot be operated in principle, so it is not too suitable for company sharing key data. The reasons are as follows: The domain name service is a distributed system, composed of thousands of domain name servers, which are controlled by different units, and only these domain name servers are well matched. When the domain name service system is designed, it is designed for the case where the IP address is relatively fixed. For example, the IP address of the host does not change within a few months. Therefore, the host cannot cooperate very well. Specifically: Each domain name server has its own cache, so after the host's IP changes, even if the dynamic domain name server has been updated, the domain name server distributed around the world is not possible to update, so the user is likely to pass the domain name. Analysis of the wrong IP address. This light will cause the server to be unacceptable, and the importance will be hacked and attack the server. There is no such problem without the messenger network. Because the host using the network does not have a real public network IP address, the external network user is accessed, the IP is actually pointing to the external server to the network (External Server). The network communication server has a permanent public IP address, so there is no domain name cache.
4, high data security
According to statistics, 99% of all network attack methods are the first step in the IP scan as an attack. In other words, as long as the hackers can't find an IP address of the target, then your host security has increased by 2 orders.
Using the network-pass data host in the firewall (NAT), there is no public IP address, and the network communication server can only know the IP address of the broadband operator, and the IP address of the real data host is completely unknown. For other users on the Internet, you can only know the IP address of the Internet server, and even the broadband operator's IP address is completely unknown, it is more unclear that the IP address of the data host. Since IP of the data server is not known, 99% of attacks are eliminated. In addition, since the server is placed inside the company, it will not be monitored. Once the attack can take measures immediately, the data backup is also very easy. Therefore, it is necessary to securely 2 orders of order by means of a message network.
In contrast, the dynamic domain name system user has an activity IP address, which is a simple and can scanned IP, and as a regular enterprise user, generally does not have an effective means of attack. Therefore, using the dynamic domain name system undoubtedly exposing ourselves to the frank of the hackers, extremely unsafe.
