The DNS (Domain Name System) is a system that translates domain names, which are easy for people to remember, into IP addresses that machines can interpret. When changing domain settings or relocating a server, it is necessary to check that the DNS information is updated correctly.
nslookup is one of the commands used to perform such a check. Specifically, it is used as follows: nslookup
nslookup xxxxxxx.comThis will retrieve information on the IP address associated with the specified domain name. However, the results you see using this method depend on the DNS server you are referencing, so you are not necessarily getting the most up-to-date information.
Therefore, when checking to see if DNS changes have been properly reflected, it is recommended that you use multiple methods and tools to check information from different DNS servers as well; DNS updates can take time to propagate to DNS servers around the world, so it is also important to wait long enough It is also important to wait long enough before performing a check.
