The principle of virtual IP, what is virtual IP? What is a virtual IP used for?

The one you are talking about is not a real IP or a fake IP, that's because we generally use private network addresses when surfing the Internet, because private network addresses cannot be on the public network, so we need to convert NAT (network address translation) into public network addresses on the router for access, when we visit the external network, we convert the private network address into a public network address, and when we come back, we convert the public network address into our private network address, so we generally use nat conversion, and the one you said is the principle of PPPOE dialing, He used a virtual IP address to dial the number.

First of all, we have a network card, a network cable, a network driver, and a "cat"...When we want to go online, a data packet is sent from our side to the server of the telecommunications company. The packet contains our keyed real IP address, virtual IP, QoS protocol, etc.

After the telecom authenticates the real IP. A packet will be sent back, and he will hide the real IP. And put the virtual IP reality on the Internet.

This way hackers and intruders will not be able to find our real IP so easily, but with a little effort, they can still be found. It's all about skill and patience. Virtual IP is to play a camouflage, convenient, and secure role.

When playing games, virtual IP conflicts are generally encountered in the LAN. It's because there are two machines with the same IP set, and it's OK to change one. This is not the case in Internet cafes or at home.

Even if Arino is caused by a server error in the game or something else!!

Rabbit! 《》Sub-dynamic IP, support mobile phones and computers, IP coverage nationwide, IP a lot.

Is there any difference between a web hosting non-dedicated IP and a web hosting dedicated IP? What are the advantages of a dedicated IP? Web hosting with non-dedicated IPs:

1.Shared IP hosting can't open your ** directly with an IP. It is shared, and a server is divided into many web hosts, which means that many ** use the same IP 3

If a hacker attack is received, then the ** of the same IP on the entire server will be affected 4If some web hosting sites on this server store illegal information and are detected by the network monitor, then the IP will be blocked (now the network is more strict), then your site will also be affected 5Search engine indexing, if a site on this server is cheating, or violates the search engine inclusion rules, or has illegal information, etc., it may be reduced by the search engine, then the ranking will be lower, and it may affect the site ranking on the entire server.

6.There are restrictions on binding domain names, there are restrictions on binding domain names to virtual hosting, and domain names need to be bound in the virtual hosting management there to resolve the domain name, so that you can access **. Web Hosting for Dedicated IPs:

1.You can directly use your own IP to open your own **. 2.

Each site is an independent IP and is completely owned for its own use. 3.If another web hosting site on one server is attacked by someone else, then your own ** is not affected.

4.If a web hosting site on the server stores illegal information, if the network supervisor blocks the IP of this site, your site will not be affected 5Improve the user's level and chance of being indexed by search engines.

If an IP corresponds to only one **, the search engine will rate the ** as high in quality and thus increase the inclusion level 6You can bind wildcard domain names (unlimited domain name binding space). After a single IP, it can realize the wildcard domain name binding function that cannot be achieved by Windows virtual machines in the past.

IP technology is a kind of enhanced network management, gives full play to the advantages of VLAN, changes the network structure, reasonably allocates network resources, balances network load, effectively reduces online broadcast information, and facilitates group management of users.

Virtual IP address (VIP).

is an IP address that is not connected to a particular computer or to a network interface card (NIC) in a computer. Packets are sent to this VIP address, but all data still goes through the real network interface.

Most of the VIPS are used for connection redundancy; A VIP address may also be available in the event of a failure of one computer or NIC, which is connected by another optional computer or NIC response. Examples of virtual IP addresses are:

It's used to confuse people by not letting others know your real IP, especially online.

Virtual IP (VIP)

A Virtual IP Address (VIP) is an IP address that is not connected to a specific computer or to a network interface card (NIC) in a computer. The introduced packets are sent to this VIP address, but all packets travel through the actual network interface. Most of the VIPS are used for connection redundancy; A VIP address may also be available in the event of a computer or NIC failure, as an optional computer or NIC responds to the connection.

An example of a virtual IP address is a loopback (circuitless IP address) as an IP address that is not associated with any particular interface (or circuit) in the host or router.

By assigning a virtual IP address to an AIX system, the IP address no longer depends on the specified network interface. The sender simply sends the packet to the virtual IP address of the receiver's server (all received packets still arrive at the server through a real physical network interface). Before a virtual IP address is used, if a network interface fails, all connections associated with it are lost.

To use a virtual IP address, the AIX system needs to provide automatic rerouting support for the virtual interface and the routers in the network, and as long as the packet can be rerouted to other network interfaces, the existing connection to the virtual IP network interface will not be interrupted. Therefore, a virtual IP address can shield the connection from failures caused by network cards, routers, etc., so that the connection is preserved. The failure of the network card does not affect the existing connection, and the use of a virtual IP address on AIX further increases the availability of the system.

At the same time, multiple NICs work together to bear the load of the system, which can reduce the centralized use of a single NIC and subnet, and solve the bottleneck caused by it. The functionality of VIPA in AIX is transparent to network devices, eliminating the need for dedicated P-Series or network devices. To implement a virtual IP address on an IBM P-Series server, you need to:

1）aix5l。(2) Two or more IP interfaces connected to the enterprise network that are not on the same subnet (regardless of physical type).

For public IP addresses

It is assigned to you by the IP management department.

You don't have a way to customize.

And if it's an intranet.

Can be customized.

But the term "virtual IP" seems too vague.

1. How to use virtual IP to surf the Internet, the first thing is to understand that your IP address is a fixed IP address provided by the broadband operator.

2. This IP address is like the house number address, so that the network can communicate data transmission and information exchange normally.

3. Because different IP addresses are needed for business, work or games, we need to switch IP addresses in different cities infinitely.

<>5. After opening the software, we can clearly see that the software has the existing IP address in all parts of the country, connect the IP you need according to your own needs, and then the IP of your computer or mobile phone will change.
