Now the IDC market is quite chaotic. Many unscrupulous businesses rent broken servers and start selling them as branded servers. Some even sell single-line space as multi-line space to deceive novice webmasters. Below, Lao Meng will share his personal experience with the majority of webmasters. The long exchange of knowledge will share the commonly used common sense in identifying multi-line spaces, as well as some commonly used deceptions by space dealers.
1. Dual-line dual-IP space
Many established space providers are still selling this kind of dual-line dual-IP space. This is the earliest dual-line form. Two network cards are inserted into a server, one is connected to the telecommunications line, and the other is connected to the China Netcom line. Many Webmaster friends will be 100% sure that it is a dual-line host when they see the dual-line dual IP. In fact, this is not the case. Some space providers with advanced technology can use VPN or accelerated lines to dress up the single-line single-IP server as dual-IP. Although it is better than the single-line The effect has been improved, but it is not the same concept as dual-line, and due to the complexity and poor stability of the technology, dual-IP technology has also reached the edge of elimination, so it is recommended that you do not buy dual-IP servers anymore.
2. Two-line single IP space
After several batches of shared servers in recent months, Lao Meng found that single IP has many advantages over dual IP. The speed is very stable. The speed difference between China Telecom and China Netcom is not very big. Dual IP will not be as fast as China Telecom and China Netcom. The speed is not ideal or Netcom users access telecommunications lines quickly but access Netcom lines too slowly. Therefore, these recent batches of shared server Lao Meng have abandoned dual-line dual-IP lines and replaced them with multi-line single-IP lines.
3. Multi-line single IP space
The new server installed by idc.cnzzq.com this month is a BGP multi-line single IP line. According to customer feedback, this type of line machine has obvious advantages over the above two technologies. Basically, all regions across the country are accessing it. The speed is very fast and the stability has always been good. This may be related to the fact that Jing'an is a large computer room. This reminds everyone that when buying a server, you must choose an old computer room or a large computer room, and do not choose a computer room that you have never heard of. , otherwise a few days without anyone will be enough to make you cry. Some space companies claim that they are five-, six- or even seven- or eight-tier spaces. This is pure nonsense. China’s main networks are China Telecom, China Unicom, Railcom, and China Mobile. I don’t know where the so-called eighth-tier networks came from.
When buying space, the more lines, the better. I have seen many so-called seven-line and eight-line ones. In fact, it turned out to be a telecom single-line one. The best way to buy multi-line single IP space is to first find a few friends with different networks. Ping it and see if the ping value differs greatly. If it differs a lot, it basically means it is not multi-line.
I'm short of time so I'll write this much first. In short, everyone remembers the most commonly used method. Try not to use dual-line dual-IP. The speed is not good and there is often a problem with either the network line or the telecommunications interface. If you must use it, check it out. Whether the two IPs are one for China Telecom and one for China Netcom, check the IP addresses to see if they are from the same place. It is recommended to choose multi-line single IP as much as possible, because there are not a few users using networks other than China Telecom and China Unicom (there are many Chinese people). When purchasing, find friends with different networks to test the speed, and try to choose one with a greater reputation. In the computer room, don’t listen to the so-called five- and eight-line hosts, they are all lies.
