The command dig allows you to query a name server for IP addresses like this:
# dig www.linuxintro.org ; <<>> DiG 9.7.3-P1 <<>> www.linuxintro.org ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 884 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.linuxintro.org. IN A ;; ANSWER SECTION: www.linuxintro.org. 14400 IN A 92.51.132.237 ;; Query time: 67 msec ;; SERVER: 192.168.0.1#53(192.168.0.1) ;; WHEN: Sat Jul 2 14:34:22 2011 ;; MSG SIZE rcvd: 52
In this example we see the IP address of www.linuxintro.org is 92.51.132.237.
The syntax of a dig call is
dig <html><acronym title="Specific DNS server">@dnsserver</acronym> <acronym title="For example linuxintro.org">domain</acronym> <acronym title="Can be ANY, A, MX, SIG, etc.. By default it is A.">type</acronym></html>
