In general, transfer servers, web site data and so on, as long as the modification of domain name resolution point to the new IP address. But there are also a few cases where you need to modify DNS for domain names. Wanseo.com reminds you to carefully modify the domain name DNS.
It takes about one hours to register to success (international domain name) from the beginning of the domain name. At that time DNS was default. That's when DNS took effect one hours. If a company or individual has a DNS server that needs to resolve the domain name with its own DNS server, it is a good idea to modify DNS before registering or registering successfully but not using the domain name formally. Once the domain name is formally used, and the DNS is modified halfway, the site will be interrupted for at least 24 hours. Because DNS changes take 24-48 hours. You can imagine the consequences of a 24-hour web site interruption visit.
