If you want to change it, you can go to the NSLookup EnvironmentRun the "set srchlist = domain name 1/domain name 2/Domain Name 3" command. to disable the NSLookup tool from attaching a domain name, you only needSrchlist =.

For a portable computer that is moved from one environment to another, when it must use a static IP address in one location, and the IP address allocated by DHCP must be used in another location, this function is particularly useful.This method is applicable to Windows 2000, Windows XP, and Windows

little about the data structure can realize that reverse queries are performed in the forward query domain. The only way to do this is to traverse the entire data set-for DNS, that is, traverse the entire database, this will bring a huge burden, so DNS adopts another method, using another subtree to maintain the corresponding table of IP-> domain name.
