dig (domain information groper) gets information from DNS servers.
dig google.com Gets DNS information for the specified hostname.
You can query for specific DNS record types:
dig MX psygen.org Look for the mail exchanger records for the specified hostname.
dig NS psygen.org Look for the name server records for the specified hostname.
... and so on for any valid record type.
Short Form
You can use the short form to view just the info you need, instead of the whole record:
dig psygen.org +short 67.225.240.117
dig psygen.org ns +short ns1.nameserver ns2.nameserver
Reverse DNS Lookup
You can also use dig to do a reverse DNS lookup (find out what domain name an IP address belongs to) (you can remove the "+short" to see the entire record)
dig -x 209.132.183.81 +short www.redhat.com.
