Search Engine: The impact of website replacement IP on the website

IP is the abbreviation of English internet Kyoto, meaning "interconnection between networks", that is, http://www.aliyun.com/zixun/aggregation/11991.html "> A protocol designed to communicate with each other in a computer network. On the Internet, it is a set of rules that enable all computer networks connected to the Internet to communicate with each other, and rules that should be followed when computers communicate on the Internet. Any computer system produced by any manufacturer can interconnect with the Internet as long as it complies with the IP protocol.

It is because of the IP protocol that the Internet has developed rapidly into the world's largest and most open computer communications network. Therefore, IP protocol can also be called "Internet Protocol". In layman's terms: IP addresses can also be called Internet addresses or Internet addresses. is used to uniquely identify the logical address of a computer on the Internet. Each network computer relies on its IP address to identify itself. It's very similar to our telephone number. Use the phone number to find the actual address of the customer who is using the phone. Telephone numbers all over the world are unique. The same is true for IP addresses.

A network protocol (IP) is a method or protocol for transferring information from one computer to another on a network. Each computer (host) on the network has at least one IP address that distinguishes it from other computers on the network. When you send or receive information (for example, an e-mail message or a Web page), the information is divided into small chunks called packets. Each packet contains the network address of the sender and recipient. The gateway computer reads the destination address, and the packet continues forward to the next neighboring gateway and reads the destination address as usual, so that it goes forward through the network until a gateway confirms that the packet belongs to the computer closest to or within its scope. The computer that eventually goes directly to the specified address.
 
Because a message is divided into many packets, each packet can be sent over a different path of the network if necessary. Packets can arrive in different order from when they are sent. Network Protocol (IP) simply delivers them. Another protocol, Transmission Control Protocol (TCP), is the ability to combine them back in the correct order. IP is a connectionless protocol, which means there is no continuous line connection between the end points of the communication. Each packet is transmitted over the network as a discrete unit of processing, and there is no correlation between these units. (packets can be put in the right place because of TCP, which is a connection-oriented protocol that understands packet order in information.) In the Open System Interconnection (OSI) communication mode, IP is located in the third tier?? Network layer. The most widely used IP version today is IPv4. However, IP version 6 (IPV6) is already in use. IPv6 for longer addresses, so it can meet the needs of more users of the network. IPV6 includes IPv4 features, and any server that supports IPV6 packets also supports IPV4 packets.

Less nonsense, say to turn, when I began to constantly understand the Webmaster Circle This group of people to the understanding of SEO, I keep on the internet, including some SEO experts and enthusiasts to write articles, SEO impact on the site or to say that the keyword ranking of the number of factors have hundreds of thousands of items, I summed up SEO as a systematic project. What I want to talk to you about today is a small piece of this project about the impact of the site change IP on the site.

Let's take a look at the working principle of the search engine, I simply say that the search engine, including spiders and index two parts, spiders (robots, reptiles) is specifically to obtain on the network, his characteristics is that you 3,721, like Black-and-white gong see ghosts are also caught, Spider back data will usually be placed in a database, if you know the collection also know this, and then there will be another program to analyze the data, collation of repetitive, garbage, and finally after the worry will go into the index database, to participate in ranking let indexing program search, According to the search principle and human habits and so on a page rating, the higher the more ranked in front.

So a site to SEO optimization is good, want to let spiders like to climb your station, and then to let the analysis program feel that your content is valuable is not deleted to the like, through the two off, congratulations on your participation in the rankings, then you have to find ways how to break through and get a good ranking.

For today I would like to say that the change of IP on the site's impact on this issue, is the first pass, so that spiders love our station. Why the switch IP may let the spider to our station's liking degree to descend?

We take a look at the process of our visit to the Web site, in the browser input URL return, and then the browser check the local host has no IP and domain name of the corresponding relationship, did not send this URL sent out, sent there, to the gateway, the gateway to see their own domain name records there is no corresponding IP Do not go to the DNS server to retrieve IP, after retrieving the IP actually we are through IP access to the site. When changing the IP, we usually will do the domain name resolution, the domain name point to the new IP, is actually updating the domain name server records. It will take some time to update the process.

In fact spiders crawl my site and we are people who visit our site a same, so in the replacement of IP this time there are two places may cause spiders can not visit our website, the first is that we update IP resolution submitted applications, domain name server in actual need in a period of time to the request, The second is that although the resolution has been changed, but spiders crawl through the domain name and IP correspondence is still old, that is to say, the domain name of the Spider-Server domain name and IP corresponding relationship has not been updated, this update is needed for some time. These two periods of time together may cause the spider for a period of time can not visit our station, imagine, when I visited you many times you ignore me, you will do??

Then I think this is the change of IP on SEO optimization impact of the important reason, like my joke network www.xiao688.com several times is because the replacement of IP and server instability to make the Spider update page is very slow. The above only for personal opinion, does not represent the right, not generation to authority, for reference only.
