Website construction and optimization Choose a stable server is essential, many webmaster in the construction of the site to buy servers often hear IDC preach: Dual-line, four-line IP resolution, more conducive to the stability of the site. Is that actually true? Don't let the illusion blind our eyes. In fact, in some well-known domestic service providers are all selected by the telecom single line IP to resolve, rather than the selection of two or more lines. Why is this happening? In the vast service providers, webmaster and how to choose a more suitable server to operate it? We do the following to analyze:

DNS Intelligent parsing and CDN acceleration

Webmaster often encountered IDC service providers claiming to be a multi-line IP server, actually encountered is the DNS intelligent resolution, rather than the use of CDN accelerated analysis. What is DNS resolution? The general IDC service providers are two or more IP to the same server, and then the user visit the site when the intelligent matching resolution. Such as: Telecommunications users visit the site so the telecommunications users to visit the IP site Telecom, Unicom users to visit the website IDC matching to the user is the IP address of Unicom, so that can play a certain acceleration effect. But the disadvantage is also obvious, because the search engine in the index site when the choice of IP, resulting in spiders crawling dizzy, more detrimental to the spider web page crawl, multi-line IP server is more likely to lead to the phenomenon of the right to fall. What's more, the webmaster know, in the two-line parsing when we parse is not a record, but Cmname alias resolution, such as: "Idc1.xxx.com", if the service provider in the absence of notice to replace the IP address? You don't have the slightest sense of it, but it leads to a precipitous decline in rankings.

CDN Acceleration can avoid such a situation, some large-scale portal sites or download stations are used in this mode. CDN Acceleration is a number of IP cache service components, different from the general DNS intelligent resolution: Because the use of CDN acceleration, so the final main station IP is only one. Because of the use of Web cache distributed network caching structure, access is high but can effectively avoid the cross service caused by slow access. The following is a more professional explanation to illustrate this problem:

Summary and Analysis:

  But CND acceleration although the effect is better, but the expensive money is unable to make small and medium-sized stationmaster accept. So the network popular double or single line IP is only DNS intelligent resolution just. and telecommunications in the speed of more than other network service providers, the choice of a guaranteed bandwidth server even if the Network service provider to visit the site will not feel very slow, so in the choice of service providers do not be fooled by false eyes. In general, single-line IP server above the author compares the recognition of the server, telecom single IP and independent IP. In this little too much explanation, I am not a todo, we all know. Binary Beijing seo (www.seostudy.org) summed up the analysis that the two-line or even multi-line IP is not advocating for everyone to buy, reasonable and effective enough is our pursuit of practical efficiency.
