Because security is connected and tied to a domain name, it is required to apply for domain name
Is there not knowing what domain name is, but we must know that access domain name is bound to the domain name to access the IP address
This domain name has the advantage that a domain can bind multiple IP.
For example: Baidu domain name is https://www.baidu.com/
Then we will visit the domain name server access to Baidu, but Baidu is certainly not a server, a server how enough because so many people visit, so there will be multiple servers, IP each server
They are not the same, and these are bound in the IP on a domain name (when the user of how to access the specific allocation of access which ip I do not know ha).
There is a benefit domain name is, if we later change the IP, in fact, does not affect the use of the domain name attached, because we only need to change the lower bound to the domain name IP can
Then fill out the purchase according to their own
Behind the purchase will not Screenshot
Then there waiting ....
If the audit Well
Now first with the binding domain on IP, so let's use the domain names to IP addresses
I added three, so www.mnifdv.cn or mnifdv.cn or XXXX.mnifdv.cn have access to
