Hi,

How can i get these details by running a single command from centralized location.

I'm not sure I understand your question. You're looking to find the whole subnet occupied by a domain? There is not neccessarily any direct relationship between the two. Please clarify.

Hi,

Sorry for the inconvenience.
I need to find the whole subnet occupied by a domain.
Help me.

Are you talking a DNS domain or a windows domain? The only thing I can think of is to try portscanning subnets adjacent to known IP addresses based on DNS lookups.

If the network is in the U.S., then querying ARIN (www.arin.net) may be of help. But as Matir says, there is not necessarily a one to one correspondence between subnets and domains (think large Web hosting providers, for instance).

Additionally, the converse is true. A company I've done some work for owns about a half-dozen disparate netblocks from ARIN. Again, you could query ARIN to try to find that information, but you will miss any IPs that are leased from other owners of IPs.
