You can whois a domain to see who the domain is registered with.

Is there anyway you can find out which company a individual is hosting with? (i.e. Rackspace, Godaddy, etc.)

The best you could do is ping / nslookup it to get the IP; and lookup who the IP belongs to. Given as an example:

PING ( 56 data bytes 64 bytes from icmp_seq=0 ttl=52 time=50.067 ms

Then doing a WHOIS on the IP Address:

VCSJONESMBP:~ kjones$ whois "n"

This approach however is flawed though. If they used a load balancing service like Elastic Load Balancing; you would probably get the IP address of the load balancer, not the actual host. The same can be said for a proxy server.

I find useful for that kind of information. Enter the domain name, click Lucky, go to the Records tab and check the AS column to see who runs the servers involved.

You can infer much by just looking at the domain's DNS records:


Non-authoritative answer:

C:\>nslookup -type=ptr

Non-authoritative answer:     name =      

First, use nslookup to find the site's IP address. Then, use the IP address to get any PTR records (reverse DNS.) Often, one (or the only) PTR record will show the hosting company's domain name (in the above example, we see that is another name for

In most cases you can do an IP lookup and this will tell you which range the IP address belongs to, often telling you which firm they're hosting with. For instance:

Shows that my company uses RackSpace.
