Several methods and ideas about Linode VPS host IP blocking and IP replacement

Last week, Lao Zuo saw a message from a netizen saying that when he opened the Linode VPS host, the IP was blocked, and this problem happened to 30 machines in a row. This netizen was also lucky. Lao Zuo had encountered 10 or so machines whose IP addresses were blocked consecutively before. according to Linode VPS The host features that we can repeatedly delete and open new machines until we find an available IP address.

In this article, Lao Zuo shared how to solve and replace the problem of IP blocking in the process of using Linode, at least not to see the netizen mention that the user needs to provide various procedures when writing a work order for customer service to replace. Generally, merchants will not change the IP address for users. We can solve the problem by ourselves.

First, repeat the opening until appropriate

Similar to Linode VPS, which can delete and activate servers at any time, we may encounter that the IP address of the activated server will not work at the beginning. Our solution is to re activate the server after deletion. The general practice of Laozuo is to directly open a few sets, then check whether there are any available ones, and then delete the unavailable ones and leave them available.

According to the feedback information received recently and the self inspection, there are relatively many IP failures in JP2 and Fremont data centers in Japan. In fact, sometimes it is lucky that there may be several or more than a dozen machine IP failures in succession.

Second, replace the data center

I also used this method in the early days, and may have mentioned it in previous articles. For example, we are currently in the Fremont machine room, and there are data and websites in it. After a period of time, the IP is blocked. If we go to backup the server and migrate data, it is really inefficient. The method we adopt is to write a work order to apply for moving the computer room to another computer room, such as Dallas. The customer service will generally give the operation, and we can cooperate with the operation.

In this way, after migrating to other computer rooms, the data is still available, but the IP address will become the IP address of the new computer room. Similarly, if we determine that Fremont machine room is needed, we can submit a work order to apply for migration after a period of time, so it is possible to apply for a new and usable IP address. However, since this method has not been used for a long time, it is recommended to back up the data if necessary.

Third, self migration of reserved IP

The above method is that we ask the customer service to migrate our computer room. Because the response speed of today's Linde customer service is not as fast as in the early years, we need to wait for them to reply to the work order and operation. It will take a long time to return. In fact, we can migrate data to other VPS through Linode cloning and IP Swap. For example, we can open a new available VPS and then clone the data.

Similarly, we can also use this method to retain the original IP address. If the IP address is blocked, we do not need to migrate the IP address. Lao Zuo will sort out the practice of this method in detail later.

In conclusion, we can see from this netizen's message that the reason for his request to change the IP address was rejected by the customer service. The customer service repeatedly stressed that he should change the IP address himself, which should also be achieved through the above method.
