Is there a service that will identify where a site is hosted (presumably by IP)?

Who-hosts is an online free service that can tell you which is the company that hosts the provided URL, and doesn't require registration.

tracert www.sitename.com
is probably your best bet. The last entry or two should give you your best hint. Otherwise, the whois entry may be a good indicator as well, especially if they are using a hosting provider for DNS.
EDIT:
Its traceroute not tracert on linux machines.

Just do a whois search on the IP.
http://samspade.org/whois/ is a free utility for telling you who owns an IP address or domain name. If this is a server farm hosting multiple servers, then it will likely be registered to the hosting company.

This isn't exactly what the question asked for, but you might find it useful to know that Netcraft provides some pretty neat information about the uptime, web-server software, and ISP used to host websites as well.

Domaintools can usually give you some pretty good information, under the "Server Data" and using the "Reverse IP" tool (though you have to pay to get full results from that one).

http://whois.domaintools.com/websitename.com
just put the website name in instead of websitename.com.

So in my network I have the main domain controller and a backup domain controller. The backup domain controller has exchange on it.
The exchange services have been shut down as I have moved email hosting off site. So I now have no need of that backup domain controller that was running exchange. I want to shut it down for good.
What would be the proper way to remove it from its role in active directory and a backup domain controller?
Both domain controllers are Server 2008.
Thanks much!
Firstly, just don't do it, this is a SysAdmin SIN! Your shooting yourself in the foot. Even for my smallest customers with only 10 members of staff, I often have them purchase a second server to act as a secondary domain controller, DNS server, DHCP Server etc.
It is the first and few things Microsoft recommends as best practice when setting up a domain and one of the first things that is taught to you when you do the MCSA course: When creating a domain a secondary domain controller should be set up. If you have more than 20 Users its a must IMHO. Many things can go wrong and too many times clients have incurred big bills(man hours) because they didnt spend that extra £2000 on another server. I strongly recommend you keep it. It's not just availability, it prevents a large number of corruption issues which can linger for weeks before presenting themselves which makes 7x daily backups no help. It's your sefety net.
If you must get rid of it, first check is doesn't hold the FSMO roles and run dcpromo following the steps here: http://technet.microsoft.com/en-us/library/cc771844(v=ws.10).aspx
Lastly, your getting down-voted because StackOverflow only like coding qustions and they want you to use ServerFault which is part of the same family.

Can you point DNS records for a domain name at a site on AppHarbor with the free account? [closed]

Just like the question says. I have deployed a site to AppHarbor, and then I updated the DNS A record for a domain name to point at the IP given on the 'Hostnames' page. The DNS hasn't updated properly yet so can't see if it's worked.
Has anyone else done this and had it work?
It will work with a free account until the 1st of March (although I am not sure if you can add them now). Then you will have to have payment information as it will cost $10 a month.
Another option is to somehow forward the web request to the *.apphb.com address.
I have some free (Canoe) applications there and the DNS worked fine for the hostnames. Although I am not at the point to really need them enough to pay for them, so I removed them and haven't tried re-adding a hostname to see if it will require payment information.

domain name prefix 'www' [closed]

In a domain name, mostly started with prefix 'www'.is it used like a standard? ifnot, let me know, why?
www stands for world wide web. Many web addresses begin with www, because of the long-standing practice of naming Internet hosts (servers) according to the services they provide.
WWW prefix
A FQDN starting with "www." is used, by convention, for the machine hosting the primary website for a domain.
These days, where websites are more important then they were in the early days of the Internet, it is conventional to also run a webserver on the main machine for the domain (i.e. example.com rather than www.example.com) (these are usually the same machine) and redirect from one to the other.

Well, I know absolutely nothing about the subject, so I really need help.
I currently have a website running on google app-engine (Java) and I can't get it to what I want because of app engine's limitations (no full text search mainly). The traffic is low, never reached 15% of the free quota (around 1500 daily pageviews).
I also have 3 sites in drupal hosted in a shared hosting service, and this is giving me problems, because the server speed is awful. The sites are VERY low trafic, but load times are bad, and I might need to add more sites for some clients, so this will only get worse.
So, i'm planning to move all that to VPS. The question is, can I have 2 http servers running in the same VPS? because I will need Apache-php-drupal server and a java server (tomcat?).
I have really no idea on this, so any tip will be very helpful to me.
Thanks!
Yes you can. Your httpd and tomcat will be running on different ports on the same server
Some of the choices you have are
Forward a virtual directory of your httpd to the tomcat server (if you use one domain name)
Use URL based rules to forward the requests from the java app domain to the tomcat server

I'm trying to block a website using the hosts file using this tutorial : http://hackspc.com/how-to-block-a-website/
but It doesn't work, the website I'v blocked In this case facebook still shows up, please can anyone help me out here?
link textI could not access the link (blocked in office) but i think this may help you edit your host file
"“WWW” has become the universal standard for the default host. It is just as common to define a site with no host as well. This means that as far as DNS goes www.yahoo.com & yahoo.com are two totally different sites, even though they resolve to the same place. Because of this to effectively block the site, you must also block all hosts. This would usually mean:
127.0.0.1 facebook.com
127.0.0.1 www.facebook.com"
check the link for more details.
Also i you trying to block multiple sites, its better to have a proper software like proxy server or firewalls which can block access to particular sites.
I think Kavitesh Singh made the most important point: Blocking the domain with and without www. this is the most common reason for an entry not working.
Also, not all browsers immediately react to changes in the hosts file. Have you tried re-starting your browser and / or system?
