how do I find a company's ip address

Hi there Clint34, 

You need to do an "nslookup".  Just plug that term into any search
engine...Google for example, and type in the URL you're looking for. 
Here's an example I found at this URL:

http://www.kloth.net/services/nslookup.php

I typed in this URL:

www.azcentral.com

And recieved this in return:

 DNS server handling your query: ns1.kloth.net
 DNS server's address:	213.133.98.149#53
 
 Non-authoritative answer:
 Name:	www.azcentral.com
 Address: 204.155.175.241
 
 Authoritative answers can be found from:
 azcentral.com	nameserver = ns4.gannett.com.
 azcentral.com	nameserver = ns1.gannett.com.
 azcentral.com	nameserver = ns2.gannett.com.
 azcentral.com	nameserver = ns3.gannett.com.
 
This *may* not work on each and every URL, but you can at least get
closer to what you're looking for by using this route.

Thanks for using Google Answers, and if you need clarification, don't
hesitate to ask.

Sorry Riccetti-ga, I addressed this answer to one of the commentors. 

Apologies again, 
Kutsavi-ga

Ping xxx.com whatever the co name is.

This is probably Verisign who controls the Domain Name Service for the
internet. Sam Spade is a good freeware program for looking up host
records, but the ping is easy, too.

What you may find is actually a Nameserver which has forwarding to the
computer IP adress that hosts the website. These are listed in order
of priority so that requests from the internet can be passed onto
backup servers in the event that the primary server is off line.

There are some services that offer Hosting By Proxy service to
disguise ownership of the domain.

The IP of a web server could also be inside a NAT, so the outsider may
see the web service provider's IP and not the actual IP assigned to
the MAC address.

A usefull web site for finding such information is dnsstuff.com

Insert the domain name (eg. www.google.com) into the "Whois Lookup" or
the "domain info" boxes on the left side of the screen.  You will get
lots of useful information about the owner of that domain including,
but not limited to, the IP addresses of their DNS servers and
sometimes web servers.  There are other tools you can play with there
as well.  All of the information is public domain, this is just an
easy site through which to access it.

If this is or one of the above answers is sufficent, please advise as
to who you would like to submit their comment the answer.  If you
still require help let us know and we'll see what we can do!

Thanks!

Hi there,
    "Beej's guide to Networking" has a program in which it gets the IP
address if u give a website address.
function gethostbyname()
Check out the program " getip.c "
Bye

just go into the dos prompt and ping the web site

go to:  http://www.samspade.org/

this site has a lot of query tools.

You can also do it yourself by going to a command prompt (start, run,
command [for win95/98] cmd [for win2000/xp].  Then enter "ping
www.domainname.com" (the URL/website address), take note of the IP
address the name resolves to, then go to: 
http://www.arin.net/whois/index.html  and enter the IP address in the
box.  Arin will give you the IP block ultimately belongs to and in
most cases who the IP has been reassigned to.

Hope this helps.

well if you work at the company you can use on of their computers and
go to www.myip.jacware.com


that will show you the IP of the computer or network.

also if you want to be able to quickly find out the IP anywhere you
could just bookmark one of the dynamic images that they have (such as
http://www.myip.jacware.com/browserip.php )


or start> run > cmd > ping (web address)


or you could use the reverse of the gethostbyaddr() PHP function...

Sorry the link was actually:

<a href="http://www.myip.jacware.com">MyIP</a>

sorry again, it is

http://www.myip.jacware.com/
