Long and wide DNS is the abbreviation of Great Wall Broadband, is a telecommunications network operation company, industry insiders generally referred to as long and wide DNS, generally used or heard of long and wide DNS people must understand some of the shortcomings of long and wide DNS.

At present, it is known that there is only one advantage of long and wide DNS, and that is cheap! However, the preferential price can not hide the shortcomings of the long and wide DNS. Let's count the shortcomings of the long and wide DNS: 1, the network speed is slow: as far as we know, there is basically no network speed for the length and width of the DNS in the afternoon and evening, with a network speed of dozens of kilogrammes, it is basically impossible to visit the web page, and it is difficult to open Baidu.

2. DNS interception: the interception of long and wide DNS is famous. This unique DNS interception usually appears on the website visited after opening the browser, jumps to the advertising page of Great Wall Broadband, and some websites also jump to the advertising page when they cannot be accessed. Moreover, this blocking cannot be blocked, so it is useless to make a phone call to complain. This is the biggest headache for most long and wide DNS users.

3. Pop-up window advertisement: this is also unique to Great Wall DNS. No network operator will pop up its own advertisement suddenly when users visit the web page, which basically challenges the bottom line of users' patience. If you encounter such a situation, please contact the Ministry of Industry and Information Technology: 12300.

Although the problems existing in the length and width DNS have been improved, they have not been well solved, so it is recommended that you choose Unicom or China Telecom around the length and width DNS.
