NSLOOKUP

NSLOOKUP (Name Server Lookup) is a program that queries a DNS server for information about the specified fully-qualified domain name or IP address. Using nslookup, you can discover a domain’s name server, look up the IP address of a specific host, look up the fully-qualified domain name for an IP address, look up the mail server for a specific domain or host, etc.

One situation in which you might use NSLOOKUP is when diagnosing a problem in which a user coming in from an Internet ISP can’t access your web server by name, but can access it by IP address.

You can use NSLOOKUP in that situation by starting the utility, looking up their nameserver, setting nslookup to temporarily use that nameserver instead of your own, and checking to see what IP address the fully-qualified domain name resolves to. If it times out or takes the user to the wrong machine, their nameserver has incorrect data.
