Domain name resolution, modify DNS and modify a record, the effect is basically the same, can be resolved to space.

But there are some obvious differences:

1, for resolution of the server is not the same. By modifying a recording method, the server responsible for resolving the work is the domain name registrar's server. By modifying the DNS method, the server responsible for resolving the work is the space merchant.

2, most of the time, modify a record mode resolution, the resolution of success faster.

3, modify DNS, when the space IP replacement, you do not have to do other operations, the system automatically parse the past. And if you modify the a record, then each time you change the IP, you need to resolve it again.

4, modify DNS, if you want to set the subdomain, point to other space, you can not achieve.

5, now most of the United States host is to support the pan-resolution, after the modification of DNS, add sub domain name, no longer operate the domain name of the resolution, and if it is by modifying a record, it is a one to resolve, very troublesome. Of course, you can also support the pan-resolution of the domain name providers there, do a pan-resolution implementation.

6, some United States host, add additional domain time, the request first DNS modified to the Space business DNS, if not modify DNS and modify a record, do not let binding domain names.
