If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
nslookup followed by the domain name will display the âA Recordâ ( IP Address ) of the domain. $ nslookup redhat.com Server: 192.168.19.2 Address: 192.168.19.2#53 Non-authoritative answer: Name: redhat.com Address: 209.132.183.181. In the above output, server refers to the IP address of the DNS server. Then the below section provides the âA Recordâ ( IP Address ) of the domain âredhat.comâ.
Now that I have shown you how to use the NSLOOKUP command to see the IP address or addresses associated with the domain, letâs do something a little bit more useful. One of the things that you can do with NSLOOKUP is to look up a specific type of DNS record. A good example of this is an MX record.ow that you have specified a DNS server for NSLOOKUP to use, you can query domains without receiving the non-existent domain error messages that you saw earlier (as long as you remain within the NSLOOKUP shell). To do so, you would simply type the domain name that you want to query.
