Is it possible to find the IP addresses of web-host servers?

I don't seem to be able to make any of the above options provide me with in IP address number :(

I have not tried Sirber's "pinging" suggestion because I'm not sure how to do this!

If you are Windows user:

Hold Windows key (beside alt keys) and press "r" at same time.
A dialog will popup.
Copy following and paste it in that dialog and press enter (or accept with left mouse button):
cmd /k ping www.yourhostname.com (or any domain your host have, net, org, etc.)

Thanks guys,

Okay I've tried "pinging" but it would seem this method does not give you the IP address of the computer that hosts the website!

Take my web site (www.SeeMoreDigital.net) for example. It's listed as having the following IP address: - Pinging server40.ukservers.net [217.10.138.240] with 32 bytes of data:

When in actual fact it is: -Quite obviously you can only find out what is in the DNS. It is quite possible that your host uses a different "frontend" IP and you use another address to manage your files. How should anyone but your host know how they are connected?

I was interested to understand how it's possible for some sneaky organizations/people to find out such information... with the possibility of hacking into your web site files :eek:

Have you had any problems with this Doom9?

The IP www.seemoredigital.net resolves to is just a redirect to your IP. A telnet-session returns:

I was interested to understand how it's possible for some sneaky organizations/people to find out such informationIf it's set up as Swede pointed out, it's quite obvious. But if your hosting company uses one IP for all customers to manage their files and accounts, and you get a separate IP for your visitors, there's basically no way of knowing. But in general it's normal that management and the actual site is availabe on the same place.. even though they may be a physically different locations.
