Small series on November 25 last year wrote a "web site by malicious pan-domain name resolution," the article, although this method can effectively solve the domain name is malicious pan-resolution problem, but the small series after the test found seemingly although not displayed content, but occasionally also included. As shown in the following illustration:

Because the small series was originally purchased in the new network domain name (later learned that many new network domain names are malicious pan resolution of the situation) plus the registration date is less than 60 days, so can not transfer domain name to other service providers. Helpless only alternative, landing domain name Analysis Control list, accidentally in the parsing record above write the hint: host name (A) (up to 20), that is, as long as the domain name A record fixed write 20, also can not be resolved. Of particular note here is the need to delete the host name resolution to * (any) records. As shown in the following illustration:

Above the red mark hidden for the true resolution of IP records, in addition to the WWW and top-level domain name resolution to the real IP, the other 18 level two domain name can be arbitrarily customized and resolved to the loopback address (127.0.0.1) or invalid IP can be (such as 222.222.222.222).

Through the above methods, generally in the next Baidu big update, these are malicious pan-resolved domain name can be basically cleared.
