"THIS WEEK'S Q&A
================
Q: How can you find an IP address when you know only the domain name.
For example, from last week's newsletter I've been using the HOSTS
file to block access to my computer from various evil spammer
organizations. What if I know that EVILSPAM.ORG is a domain name I
want to block then how can I get their IP address?
A: The IP address is the secret code number -- 123.456.789.0 -- used
internally by the Internet to represent a domain name. It's like a
phone number, though thanks to various Domain Name Servers (DNS), we
can type in things like www.evilspam.org and get to a web page as
opposed to having to remember a number like http://123.456.789.0/.
Anyway!
If you have Windows XP, then you're fortunately enough to have a
command line utility borrowed straight from UNIX: The NSLOOKUP
command can be used to find the IP address(es) associated with any
given domain name.
1. From the Start panel choose Programs>Accessories>Command Prompt.
2. Type NSLOOKUP, a space, then a domain name. For example:
NSLOOKUP WAMBOOLI.COM
The NSLOOKUP program then spits out your DNS server name and its
address, followed by the domain you entered and its IP address, or
216.18.170.33 for WAMBOOLI.COM.
NSLOOKUP MICROSOFT.COM
The above command spits out several IP addresses, all of which are
used by Microsoft to host various MICROSOFT.COM services for the
Internet.
NSLOOKUP EVILSPAM.ORG
Unless someone has registered EVILSPAM.ORG, you'll find that this
domain name is not currently in use; the program tells you that it's
a "Non-existent domain."
There are other tools on the Internet you can use to discover a
domain's IP address. So if you have another version of Windows (which
lacks the NSLOOKUP command), you can use these sites to find out
which IP address goes with which domain:
