放blog的DigitalOcean VPS的IP被墙了。虽然没有直接换IP的功能，但也并不算麻烦。简单的说就是创建一个当前droplet的snapshot，用snapshot新建一个droplet，然后把当前被墙掉的droplet删掉就可以了。这期间不会产生什么额外的费用。
如果不是用snapshot创建droplet的那个页面操作比较奇怪以至于我弄错好几次的话，全程应该用不了10分钟。另外snapshot默认只存放在创建的数据中心上，要换地方的话得到设置里面去distribute一下。用snapshot创建droplet的功能应该是搞成下面这样。
以下是我询问DigitalOcean客服的时候他们给的回信：
Hey there,
Thanks for reaching out to us about changing your IP address!
My name is Mike, a Platform Support Specialist at DigitalOcean :)
Unfortunately this is not a feature we currently support directly from the control panel but this is a feature we are working on and planning on implementing in the future. In the meantime I do have a workaround for your question.
In order to change the IP address of a droplet you would need to power it down and create a snapshot first. Once the snapshot is created, you then need to create a new Droplet based on that snapshot. The important part is creating this new droplet before destroying the old one so a different IP address is assigned to it. Once the new Droplet is created it will have a different IP address. Once you are satisfied with the new Droplet you can then destroy the old one if necessary.
I hope this has been helpful! Please let us know if you need anything else.
Regards,
Mike
