Believe that the webmaster are not unfamiliar with this, and most of the webmaster have their own domain name, a small number of at least can contact the company's domain name. Domain names can only be accessed by the outside world if they are resolved successfully. Therefore, it can be said that the domain name resolution is to ensure that the site can be normal access to the basis, once the parse error or not stable, will have a profound impact on the site. Then we webmaster have used in these years what DNS domain name resolution server? Foreign is not much to say, the following Cerviño SEO team ice ze to introduce you to a few domestic DNS domain name resolution service providers.

First: The new network

Why are you talking about the new net first? Not because the new network is the largest, but my own first domain name is registered in the new network, but also with the new network of the resolution, so the new network more familiar with some, but these years of analytic process, can use four words to describe, "miserable." The resolution of the new network as a whole can be, but the stability is not good, the site is always a few minutes a day can not open, but once I found that no meeting to submit the problem, the new network technology will be very timely repair, although the service attitude and speed are OK, but I think it is impossible for me to stare at my site every day, So then decisively abandoned the use of the new network DNS resolution. The resolution of the new network has A,CNAME,MX and so on, parsing server has ns.xinnetdns.com,ns.xinnet.cn,ns2.xinnet.cn and so on.

Second: million nets

The latest data show that China's largest domain name Analysis service provider is million nets, but I did not use, the company's website has been using million nets, problems can not open the situation is very rare, relative to the new network stability better. Others have no actual experience, bad judgment. Million network of analytical methods such as A,ns,mx,url, parsing server dns1.hichina.com and dns2.hichina.com.

Third: Dnspod

Four: Baidu accelerated music

Baidu Accelerated music I was just using, because before the Web site domain name in the new network has done a pan-resolution, leading to serious down the right, so I put my own personal domain name resolution has changed to the Baidu accelerated music, of course, not only because of this reason, at that time with the Security Alliance site Vulnerability detection to detect a lot of loopholes, according to the solution given the hint, So only to change to the Baidu accelerated music, the use of a period of time is really faster to open the speed of a lot, but also defensive attacks, so very good, the only insufficient is since the use of Baidu accelerated music, the site will occasionally appear 503 errors. Baidu's explanation for this problem is that if there are 503 error reasons are as follows: 1, the engine room or server firewall intercepted node 2, due to line reasons, node temporarily inaccessible server 3, your source site can not open. Baidu speed up the analysis of the way there are four kinds, are: a,mx,txt,cname, parsing server is mainly ns1.jiasule.net and ns2.jiasule.net.
